Mar. 28, 2013 ? An international team of physicists has proposed a revolutionary laser system, inspired by the telecommunications technology, to produce the next generation of particle accelerators, such as the Large Hadron Collider (LHC).
The International Coherent Amplification Network (ICAN) sets out a new laser system composed of massive arrays of thousands of fibre lasers, for both fundamental research at laboratories such as CERN and more applied tasks such as proton therapy and nuclear transmutation.
The results of this study are published today in Nature Photonics.
Lasers can provide, in a very short time measured in femtoseconds, bursts of energy of great power counted in petawatts or a thousand times the power of all the power plants in the world.
Compact accelerators are also of great societal importance for applied tasks in medicine, such as a unique way to democratise proton therapy for cancer treatment, or the environment where it offers the prospect to reduce the lifetime of dangerous nuclear waste by, in some cases, from 100 thousand years to tens of years or even less.
However, there are two major hurdles that prevent the high-intensity laser from becoming a viable and widely used technology in the future. First, a high-intensity laser often only operates at a rate of one laser pulse per second, when for practical applications it would need to operate tens of thousands of times per second. The second is ultra-intense lasers are notorious for being very inefficient, producing output powers that are a fraction of a percent of the input power. As practical applications would require output powers in the range of tens of kilowatts to megawatts, it is economically not feasible to produce this power with such a poor efficiency.
To bridge this technology divide, the ICAN consortium, an EU-funded project initiated and coordinated by the ?cole polytechnique and composed of the University of Southampton's Optoelectronics Research Centre, Jena and CERN, as well as 12 other prestigious laboratories around the world, aims to harness the efficiency, controllability, and high average power capability of fibre lasers to produce high energy, high repetition rate pulse sources.
The aim is to replace the conventional single monolithic rod amplifier that typically equips lasers with a network of fibre amplifiers and telecommunication components.
G?rard Mourou of ?cole polytechnique who leads the consortium says: "One important application demonstrated today has been the possibility to accelerate particles to high energy over very short distances measured in centimetres rather than kilometres as it is the case today with conventional technology. This feature is of paramount importance when we know that today high energy physics is limited by the prohibitive size of accelerators, of the size of tens of kilometres, and cost billions of euros. Reducing the size and cost by a large amount is of critical importance for the future of high energy physics."
Dr Bill Brocklesby from the ORC adds: "A typical CAN laser for high-energy physics may use thousands of fibres, each carrying a small amount of laser energy. It offers the advantage of relying on well tested telecommunication elements, such as fibre lasers and other components. The fibre laser offers an excellent efficiency due to laser diode pumping. It also provides a much larger surface cooling area and therefore makes possible high repetition rate operation.
"The most stringent difficulty is to phase the lasers within a fraction of a wavelength. This difficulty seemed insurmountable but a major roadblock has in fact been solved: preliminary proof of concept suggests that thousands of fibres can be controlled to provide a laser output powerful enough to accelerate electrons to energies of several GeV at 10 kHz repetition rate -- an improvement of at least ten thousand times over today's state of the art lasers."
Such a combined fibre-laser system should provide the necessary power and efficiency that could make economical the production of a large flux of relativistic protons over millimetre lengths as opposed to a few hundred metres..
One important societal application of such a source is to transmute the waste products of nuclear reactors, which at present have half-lives of hundreds of thousands of years, into materials with much shorter lives, on the scale of tens of years, thus transforming dramatically the problem of nuclear waste management. CAN technology could also find important applications in areas of medicine, such as proton therapy, where reliability and robustness of fibre technology could be decisive features.

LONDON (Reuters) - British scientists have developed a new vaccine against foot-and-mouth disease that is safer and easier to manufacture, an advance they believe should greatly increase production capacity and reduce costs.
The technology behind the livestock product might also be applied to make improved human vaccines to protect against similar viruses, including polio.
The new vaccine does not require live virus in its production - an important consideration as foot-and-mouth disease (FMD) is extremely infectious and vaccine facilities handling virus samples are difficult to secure.
"It spreads like wild fire," said David Stuart, a professor of biology at the University of Oxford, who led the research.
A 2007 outbreak of FMD in southeast England, for example, was traced to a nearby vaccine site. The same facility, ironically, is home to some of the researchers behind the new vaccine.
In contrast to standard FMD livestock vaccines, the new product is made from synthetic empty protein shells containing no infectious viral genome, scientists reported in the journal PLOS Pathogens on Wednesday.
This means the vaccine can be produced without expensive biosecurity and does not need to be kept refrigerated.
"One of the big advantages is that since it is not derived from live virus, the production facility requires no special containment," Stuart said.
"One could imagine local plants being set up in large parts of the world where foot and mouth is endemic and where it still remains a huge problem."
Worldwide, between 3 billion and 4 billion doses of FMD vaccine are administered every year but there are shortages in many parts of Asia and Africa were the disease is a serious problem.
Current standard vaccines are based on 50-year-old technology, although U.S. biotech company GenVec last year won U.S. approval for a new one.
The purely synthetic British vaccine has so far been tested in small-scale cattle trials and found to be effective.
Stuart said the research team from the universities of Oxford and Reading and two state-funded bodies - Diamond Light Source and the Pirbright Institute - would now conduct larger tests while discussing the vaccine's commercial development.
"We are talking to a potential commercial partner," Stuart told Reuters, adding that it would probably take around six years to bring the new vaccine to market. He said it was too early to give an indication of how much the vaccine would cost.
He declined to name the company involved but said it was not Merial, the animal health division of Sanofi that shares Pirbright's site in southeast England.
Stuart and his colleagues were able to produce empty protein shells to imitate the protein coat that surrounds the FMD virus using Diamond's X-ray system to visualize images a billion times smaller than a pinhead.
The same approach could in future be used to make empty shell vaccines against related viruses such as polio and hand-foot-and-mouth, a human disease that mainly affects infants and children, the researchers said.
Eric McCormack in "Romeo Killer: The Christopher Porco Story."
In a development that could reverberate throughout the entertainment industry, a New York Supreme Court judge has taken the bold step of enjoining the broadcast of Lifetime Television's telefilm "Romeo Killer: The Christopher Porco Story," which was scheduled to air Saturday.
The film is based on the true story of the murder of Peter Porco and the attempted murder of his wife, Joan Porco; the resulting criminal investigation; and the prosecution and conviction of their son, Christopher Porco, for those crimes. The case drew national news attention, and Lifetime's planned film drew a lawsuit from the convicted killer, who alleges that "Romeo Killer" violates his rights.
PHOTOS: 10 TV Trials that shook the world
On Tuesday, Judge Robert Muller issued an injunction that not only prevents the airing but also prohibits Lifetime from promoting the film, which stars Matt Barr as Chris Porco, Lolita Davidovich as his mother and Eric McCormack as the case's lead detective. In reaction, Lifetime is filing an emergency application to vacate or stay the injunction on appeal. According to court documents, the cable network says it stands to lose more than $1 million if it is not given immediate appellate relief.
As of Wednesday morning, there was no mention of "Romeo Killer" on Lifetime's homepage, and its promotional links to the telefilm had been disabled.

Throughout the years, publicity rights has become a bigger and bigger issue in entertainment. The laws vary by state but generally protect an individual's likeness from being exploited. Increasingly, the boundaries between an individual's right to protect an image and First Amendment allowances on free expression aren't particularly clear, and some lawyers wonder if the confusion might chill speech.
This has the potential of being one of those cases.
Porco sued Lifetime, claiming that the film violated New York Civil Rights Section 51, the state's version of publicity rights, which allows a person to seek redress if his or her "name, portrait, picture or voice is used ? for advertising purposes or for the purposes of trade without the written consent first obtained."
The jailed killer, who hasn't seen "Romeo Killer," ?alleged that the movie was a ?substantially fictionalized account ... about plaintiff and the events that led to his incarceration."
Lifetime counters that "the essential elements of the movie are true and accurate and based on court and police records, interviews with persons involved, and historical and other documents."
STORY: Lifetime prepping Jodi Arias TV movie
The cable network also points out that Porco's story has been told on CBS' "48 Hours Mystery" and the TruTV series "Forensic Files."
Without even getting a summons, Lifetime now has been ordered to not air its telefilm. Muller has issued an injunction, finding that "Defendant appears to concede that the movie is fictionalized." The judge has said that he is "not persuaded" that monetary damages would be sufficient redress and also has waved away Lifetime's concern that the injunction represents a "prior restraint" on its free speech rights.
According to an appeal that Lifetime is filing -- obtained by The Hollywood Reporter -- "The Supreme Court?s order is unprecedented and would cause grave and irreparable damage not just to Lifetime but to the constitutional protections for speech."
Lifetime cites many landmark rulings that are supposed to restrain judges from making prior restraints on free expression and says: "This is not a case where national security concerns are in jeopardy. It is not even a case involving potential irreparable injury from the disclosure of trade secrets or other confidential information; it involves a movie based on the public facts of a murder prosecution. While plaintiff may not want the story of his crime repeated in a television movie, the constitutional protection of speech and press on matters of public concern flatly prevent the issuance of an order enjoining the broadcast of the movie."
The defendant also makes the case that its film fits the "newsworthy" exceptions to New York's publicity rights law and that claims of a story being "fictionalized" don't overcome that.
Lifetime also says that Porco hasn't made a sufficient case about the irreparable harm he'll face if the film is aired and says that the balance of hardships tips entirely in its favor.
After spending $2 million to acquire the rights to the film and nearly $1 million to promote the movie as "appointment viewing," Lifetime says an injunction would have a "devastating financial and reputational impact" on the network, that it "will lead to a reluctance among cable affiliates and advertisers to spend money on Lifetime," that TV viewers "will come to see Lifetime as unreliable and not trustworthy" when they find that the program doesn't air as scheduled, that advertisers will have to be made whole, that local cable operators will be out from their own investments in advertising and more.
Says the network, "Even now, Lifetime employees are scrambling to comply with the Supreme Court?s order at great cost in human and financial resources."
Hunting for meat impacts on rainforestPublic release date: 20-Mar-2013 [ | E-mail | Share ]

Hunting for meat in the African rainforests has halved the number of primates. However, the hunting also has other negative consequences. The decline in the number of primates causes a reduction in the dispersal of seed by the primates, and this leads to a reduction in the numbers of important fruit trees and changes to the rainforest. This has been shown in new research from Lund University in Sweden.
The destruction of the world's rainforests is generally recognised as a major problem. However, it is not only felling and clear-cutting that change the rainforest. A research project at Lund University has looked at the effects of hunting on the forest. The researchers studied rainforests in Nigeria, where the local population hunts for food. The animals that are hunted include almost all mammals, including gorillas and chimpanzees and some small species of monkey.
"Hunting has a dramatic effect on the composition and structure of the forest, just as logging does, but without felling any trees", said Ola Olsson, a researcher at the Department of Biology, Lund University.
Both apes and small monkeys play an important role in seed dispersal in the rainforest, as they feed on a variety of different fruits. As the number of primates declines as a result of hunting, their seed spreading role also declines. If fewer fruit seeds are spread, fewer fruit trees will grow in the forests. Instead, species with wind-dispersed seeds will most likely take over.
Ola Olsson stressed that the present study does not give any definite answers to how the composition of the forests could change, but in his view, there could well be an increase in bushes and lianas. This would also have negative consequences for the local population.
"Many of the trees which have seeds that are dispersed by primates are also important to people, because those who live in the vicinity of the forests gather a lot of fruit and nuts", he said.
Moreover, a vicious circle arises, because primates cannot live in a forest without fruit trees. Ola Olsson would like to see better protection for nature reserves and national parks, and better information and education of local people in the villages. He remarked that the reasons for the hunting are somewhat complex. The meat forms a cheap and accessible source of protein for poor people, as well as a source of income if the carcasses can be sold in the towns, where people are prepared to pay high prices for ape meat.
"All our study sites are in protected areas, but the protection is insufficient", said Ola Olsson.
The trees also have other ecosystem functions, in the form of carbon sequestration and effects on nutrient cycling and retention. The researchers fear that when the composition of the tree species changes, there will be a knock-on effect on these processes. The study, which Ola Olsson has carried out together with Nigerian researcher Edu Effiom, has been published in the scientific journal Proceedings of the Royal Society B: http://rspb.royalsocietypublishing.org/content/280/1759/20130246.abstract?sid=90e0d3d8-8566-49b8-a129-2cc00fc2a2d3

NICOSIA, Cyprus (AP) ? Cypriot government officials sought Tuesday to alleviate the pain on small savers from a plan to raid bank deposits that has caused outrage in the country and sent jitters through European financial markets.
Just hours ahead of an expected vote in the country's 56-member Parliament on the seizure of a percentage of deposits, officials sought to limit the impact on small savers. They even hinted that the country was looking to limit the amount it is to raise from the measure's imposition ? a move that could cover any shortfall from freeing smaller deposits from the charge.
A new draft bill discussed in Parliament's finance committee proposed to spare all deposits below ?20,000 ($25,900) from a levy. Those between ?20,000 and ?100,000 ($129,290) would still have a 6.75 percent charge imposed, and those above ?100,000 would be hit for 9.9 percent, in line with the original plan put forward at the weekend.
A vote in favor of the bank account confiscation is needed if Cyprus is to get ?10 billion in rescue loans from its euro partners and the International Monetary Fund. The seizure of deposits is meant to raise ?5.8 billion, which is part of the country's rescue.
If the vote fails to get through Parliament, Cyprus faces potential bankruptcy and a possible from the euro, which could reignite concerns in financial markets over the future of the single currency.
Although Cyprus is the smallest eurozone country to be bailed out, the details of the plan sent shockwaves through the single currency area as it was the first time European authorities have targeted people's bank accounts. Other bailed out countries such as Greece, Ireland and Portugal have raised funds through imposing new taxes.
Proponents of the Cypriot account levy argue that this way gets foreigners who have taken advantage of Cyprus's low-tax regime to share the cost of the bailout of the country's banks, which have been hit hard by their over-exposure to bad Greek debt.
About a third of all deposits in Cypriot banks are believed to be held by Russians. As lawmakers wrangled, Finance Minister Michalis Sarris was to fly to Moscow Tuesday afternoon to meet with his Russian counterpart.
Opponents point out that a blanket charge on people's bank accounts will hurt ordinary Cypriots more, and could shake the confidence of all in the country's banking sector. And by going after deposits, European policymakers have set a precedent that could be repeated in the future. The worry of bank runs across Europe lies at the heart of the concerns in markets at the moment.
In a sign of the scale of disagreement over the deposit charge, the country's central bank governor, Panicos Demetriades, recommended that no accounts below ?100,000 be touched. That level represents the amount of savings that are supposed to be insured if a bank collapses.
"We believe that deposits up to ?100,000 should not be levied," said Demetriades. "The credibility of and trust in the banking sector depends on this."
Banks have been shut until Thursday to prevent a bank run. Demetriades said he expects at least 10 percent of deposits to be withdrawn when the banks re-open.
"We expect outflows, but the European Central Bank has assured us that it will provide adequate liquidity to the banks because it will consider them viable," he said.
Eurozone finance ministers held a telephone conference Monday night, and concluded that small depositors should not be hit as hard as others. They said the Cypriot authorities should stagger the deposit seizures more, but insisted that the overall take should stay the same.
The new Cypriot proposal, if approved, would raise less funds than the ?5.8 demanded. It was unclear how the shortfall might be made up.
However, Cyprus President Nicos Anastasiades told German Chancellor Angela Merkel in a telephone conversation Monday night that "the possibility of reducing the requirements from self-raised funds is being explored," government spokesman Christos Stylianides said Tuesday.
The two leaders were expected to speak again on Tuesday, Stylianides said.
Cyprus's central bank governor noted that the ECB "believes we have to try to protect guaranteed deposits."
Demetriades stressed the importance of the bill being voted on and passing in Parliament.
"It's important for the future of the banking sector and the economy that this bill is passed," he said in the committee meeting, adding that "we believe that once trust is restored, deposits will return."
Christine Lagarde, the head of the International Monetary Fund which is participating in Cyprus's bailout, said in Frankfurt that the IMF was "extremely supportive of the Cypriot authorities' intentions to introduce more progressive rates in the one-off tax."
Fivetran, a new Y Combinator-backed startup that is launching today, wants to bring spreadsheets into the modern age and make it easier for users to work with messy data and analyze large amounts of information. Most people, for better or worse, use their spreadsheets as databases, and Fivetran acknowledges this by combining SQL-like queries with standard spreadsheet functions and statistical tools that will look familiar to users of more advanced tools like Matlab. As the co-founders George Fraser (CEO) and?Taylor Brown (head of product) told me earlier this week, the idea behind the project is that “spreadsheets have 50 percent of the power of programming and we want to bring the other 50 percent to spreadsheets.” As the founders told me, there is still a huge gulf between tools like Excel and Matlab. The earliest prototypes of Fivetran still leaned more toward the Matlab side of things and looked more like a programming environment. Today, however, the service is more like a regular spreadsheet with extensive wizards that guide you through complex data transformations (including regression models) and the SQL-like selects and joins, as well as the tools data cleaning and text-mining features. Because the calculations happen in the cloud (on Amazon’s EC2 platform), spreadsheets can be extremely large and complex. The service, which the team started working on last December, allows users to upload Excel documents, as well as CSV and JSON files and start working with them immediately (in the long run, the team plans to add direct connections to databases, too). To give people a better idea of the power of Fivetran, the founders also created a March Madness bracket simulator, as well as a set of tutorials. Once they have added their initial data, users can manipulate it using Fivetran’s “step” system, which allows them to create additional sheets based on their calculations. This is a bit of a departure from how most spreadsheets work, but you can also still use your familiar Excel formulas (think SUM(a,b) etc.) to work with your data as well. The team is currently working on adding unit testing and a revision control system for spreadsheets. Fivetran is using an interesting pricing model that is a bit similar to what you would expect from a hosting provider. There are free accounts that allow you to create up to five projects that can use up to 1GB of memory. Basic accounts start
New ultra-efficient HPC data center debutsPublic release date: 19-Mar-2013 [ | E-mail | Share ]
Contact: David Glickson david.glickson@nrel.gov 303-275-4097 DOE/National Renewable Energy Laboratory
Scientists and researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) are constantly innovating, integrating novel technologies, and "walking the talk." Since 1982, NREL has won 52 R&D 100 Awards known in the research and development community as "the Oscars of Innovation" for its groundbreaking work.
When it came time for the lab to build its own high performance computing (HPC) data center, the NREL team knew it would have to be made up of firsts: The first HPC data center dedicated solely to advancing energy systems integration, renewable energy research, and energy efficiency technologies. The HPC data center ranked first in the world when it comes to energy efficiency. The first petascale HPC to use warm-water liquid cooling and reach an annualized average power usage effectiveness (PUE) rating of 1.06 or better.
To accomplish this, NREL worked closely with industry leaders to track rapid technology advances and to develop a holistic approach to data center sustainability in the lab's new Energy Systems Integration Facility (ESIF).
"We took an integrated approach to the HPC system, the data center, and the building as part of the ESIF project," NREL's Computational Science Center Director Steve Hammond said. "First, we wanted an energy-efficient HPC system appropriate for our workload. This is being supplied by HP and Intel. A new component-level liquid cooling system, developed by HP, will be used to keep computer components within safe operating range, reducing the number of fans in the backs of the racks."
Next, the NREL team, which included the design firms SmithGroupJJR and the Integral Group, created the most energy-efficient data center it could to house and provide power and cooling to the HPC system. High-voltage (480 VAC) electricity is supplied directly to the racks rather than the typical 208 V, which saves on power electronics equipment, power conversions, and losses. Energy-efficient pumps largely replace noisy, less-efficient fans.
"Last but not least, we wanted to capture and use the heat generated by the HPC system," Hammond said. "Most data centers simply throw away the heat generated by the computers. An important part of the ESIF is that we will capture as much of the heat as possible that is generated by the HPC system in the data center and reuse that as the primary heat source for the ESIF office space and laboratories. These three things manifest themselves in an integrated 'chips-to-bricks' approach."
Like NREL's Research Support Facility, the ESIF HPC data center did not cost more to build than the average facility of its kind. It actually cost less to construct than comparable data centers and will be much cheaper to operate. NREL's approach was to minimize the energy needed, supply it as efficiently as possible, and then capture and reuse the heat generated.
"Compared to a typical data center, we may save $800,000 of operating expenses per year," Hammond said. "Because we are capturing and using waste heat, we may save another $200,000 that would otherwise be used to heat the building. So, we are looking at saving almost $1 million per year in operation costs for a data center that cost less to build than a typical data center."
Warm-Water Cooling Boosts Data Center Efficiency
The ultra-efficient HPC system in NREL's new data center has been designed in collaboration with HP and Intel. The HPC system will be deployed in two phases that will include scalable HP ProLiant SL230s and SL250s Generation 8 (Gen8) servers based on eight-core Intel Xeon E5-2670 processors as well as the next generation of servers using future 22nm Ivy Bridge architecture-based Intel Xeon processors and Intel Many Integrated Core architecture-based Intel Xeon Phi coprocessors. The first phase of the HPC installation began in November 2012, and the system will reach petascale capacity in the summer of 2013.
In the spirit of overall energy efficiency, the Intel Xeon Phi coprocessor delivers on several fronts. According to Intel, it can easily port complete applications in a short time, so software engineers won't need specialized tools or new languages to support significant software packages. "Intel coprocessors also increase the efficiency of computer resource usage," said Stephen Wheat, general manager of high performance computing at Intel. "The methods of code optimization for Xeon Phi are identical to what one does to make the most of Xeon processors. Finely tuned optimizations for Xeon Phi almost always result in a better-performing source code for Xeon processors. As the optimized and tuned application is run in production, the achieved performance per watt on both Xeon Phi and Xeon processors allows achieving the results with the lowest energy use."
While some of the NREL HPC components may be off the shelf, the team is taking a different approach in cooling this supercomputer.
"In traditional computer systems, you have a mechanical chiller outside that delivers cold water into the data center, where air-conditioning units blow cold air under a raised floor to try to keep computer components from overheating," Hammond said. "From a data center perspective, that's not very efficient; it's like putting your beverage on your kitchen table and then going outside to turn up the air conditioner to get your drink cold."
"NREL's ultimate HPC system is currently under development and will be a new, warm-water cooled high-performance system," said Ed Turkel, group manager of HPC marketing at HP. "It will be a next-generation HPC solution that's specifically designed for high power efficiency and extreme density, as well as high performance things that NREL requires."
Starting this summer, NREL's HPC data center will require just over 1 megawatt of power to operate. "That's a lot of power; the heat dissipated from that is very substantial," Hammond said. "Getting the heat directly to liquid rather than through air first and then to liquid is the most efficient way to utilize it."
Water being supplied to the servers will be approximately 75 degrees Fahrenheit; the water returning from the HPC will be in excess of 100 degrees Fahrenheit and is designed to be the primary source of heat for ESIF's office and lab spaces. Data-center waste heat is even used under the front plaza and walkway outside the building to help melt snow and ice. Thus, the heat byproduct from the data center will also improve safety around the ESIF.
Compared to a typical data center, NREL's HPC data center will be much warmer. The 75-degree-Fahrenheit design point is a higher starting temperature for computer cooling. Starting at this temperature allows NREL to eliminate compressor-based cooling systems and instead use cooling towers. In a data center, this is comparable to a homeowner using an energy-efficient swamp cooler rather than an air conditioner. In addition, the pump energy needed to move liquid in the cooling system is much less than the fan energy needed to move the air in a traditional data center. Water is about 1,000 times more effective than air in terms of the thermodynamics, or the heat exchange.
"We're quite enamored with NREL being able to reuse the heat for the building and parts of the campus," Wheat said. "While others have done this before, here we are looking at a combined total efficiency goal and not just harvesting heat. We're looking to see how this can be the best solution for the entire campus."
Using the HPC's waste heat to boost the ESIF's sustainability and finding unique solutions to cut the data center's PUE are just what NREL does. "This is in our DNA; it is part of our mission at the lab, and we want others to follow suit," Hammond said. "NREL isn't one-of-a kind in what we are doing but we've set out to be the first of a kind. For us, it just makes sense. Others can follow suit if it makes dollars and sense."
The lab's industry partners also see a long-term relationship for energy efficiency and HPC, especially when it comes to exascale computing.
"We see the area of HPC as being insatiable; people will have a need for ever-greater performance," Wheat said. "One of the things we are mindful of is that while our systems are becoming denser in terms of footprint, they are becoming more power efficient. NREL is the premiere place to demonstrate a means to continue the growth of HPC capability in an environmentally friendly way."
HP's Turkel echoes that sentiment: "As power-efficient and dense as our HPC systems are, to meet our customer's rapidly expanding requirements for performance, we would need to grow even our most powerful and efficient system to be impractically large and complex, while consuming enormous amounts of energy.
"To get to the levels of scale that our customers are demanding of us, we have to fundamentally change the dynamic around power, density, and performance," Turkel added. "We have to be able to do it in a much smaller package using less energy. This project is a step in that direction and it's apropos that NREL is a partner in the effort."
"eBay, Facebook, and others have data centers that are water capable, but there aren't any products on the market now that are providing liquid cooling," Hammond said. "NREL is getting the first product that is direct-component liquid cooled. We're going to show it's possible, efficient, safe, and reliable."
Expanding NREL's View into the Unseen
The $10 million HPC system will support the breadth of research at NREL, leading to increased efficiency and lower costs for research on clean energy technologies including solar photovoltaics, wind energy, electric vehicles, buildings technologies, and renewable fuels.
The new system is crucial to advancing NREL's mission and will enable scientists to address challenges that have been intractable to date. The new system will greatly expand NREL's modeling and simulation capabilities, including advancing materials research and developing a deeper understanding of biological and chemical processes. "Modeling and simulation capability is a key part of advancing our technologies," Hammond said. "It allows us to do research we can't do experimentally because it would be too expensive, or would take too long if actual systems were built. We can mathematically model and run numerical simulations that allow us to understand things through direct observation."
Before building an HPC data center in the ESIF, NREL had a small system on its campus, while collaborating with Sandia National Laboratories on the RedMesa supercomputer to bridge the gap until NREL had a facility to house its own HPC system. For the past two years, the NREL/Sandia solution has been oversubscribed. "We averaged 92% utilization day in and day out; we needed much more capable systems to meet growing demand for modeling and simulation," Hammond said.
According to Hammond, NREL will also reach out to the local utility to study demand-response scenarios. "There are times in summer when electricity demand is high that we could shed load with the data center to help Xcel Energy." NREL could alter workloads and schedule particular jobs to run in mornings when there's a high demand for heat and cooling is less expensive. In another scenario, NREL could schedule workloads to take advantage of lower electricity costs or be mindful of when rates are higher to help reduce operating expenses. "There is a lot of interest in looking at how to integrate the HPC system in the building automation system as part of the energy systems integration work that we're doing," Hammond said.
"The computational activities at NREL had to be part of the efficiency equation," said Wheat. "A motivation for Intel to work with NREL was the ability to work together to validate how to do an efficient data center. We needed to be able to assure that we had the right balance of processor performance for the workload with a performance-per-watt focus. Being a partner with NREL in this process is of value to us for demonstrating leadership in our community. Others are taking notice of what NREL has done; I believe we all benefit from that."

New ultra-efficient HPC data center debutsPublic release date: 19-Mar-2013 [ | E-mail | Share ]
Contact: David Glickson david.glickson@nrel.gov 303-275-4097 DOE/National Renewable Energy Laboratory
Scientists and researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) are constantly innovating, integrating novel technologies, and "walking the talk." Since 1982, NREL has won 52 R&D 100 Awards known in the research and development community as "the Oscars of Innovation" for its groundbreaking work.
When it came time for the lab to build its own high performance computing (HPC) data center, the NREL team knew it would have to be made up of firsts: The first HPC data center dedicated solely to advancing energy systems integration, renewable energy research, and energy efficiency technologies. The HPC data center ranked first in the world when it comes to energy efficiency. The first petascale HPC to use warm-water liquid cooling and reach an annualized average power usage effectiveness (PUE) rating of 1.06 or better.
To accomplish this, NREL worked closely with industry leaders to track rapid technology advances and to develop a holistic approach to data center sustainability in the lab's new Energy Systems Integration Facility (ESIF).
"We took an integrated approach to the HPC system, the data center, and the building as part of the ESIF project," NREL's Computational Science Center Director Steve Hammond said. "First, we wanted an energy-efficient HPC system appropriate for our workload. This is being supplied by HP and Intel. A new component-level liquid cooling system, developed by HP, will be used to keep computer components within safe operating range, reducing the number of fans in the backs of the racks."
Next, the NREL team, which included the design firms SmithGroupJJR and the Integral Group, created the most energy-efficient data center it could to house and provide power and cooling to the HPC system. High-voltage (480 VAC) electricity is supplied directly to the racks rather than the typical 208 V, which saves on power electronics equipment, power conversions, and losses. Energy-efficient pumps largely replace noisy, less-efficient fans.
"Last but not least, we wanted to capture and use the heat generated by the HPC system," Hammond said. "Most data centers simply throw away the heat generated by the computers. An important part of the ESIF is that we will capture as much of the heat as possible that is generated by the HPC system in the data center and reuse that as the primary heat source for the ESIF office space and laboratories. These three things manifest themselves in an integrated 'chips-to-bricks' approach."
Like NREL's Research Support Facility, the ESIF HPC data center did not cost more to build than the average facility of its kind. It actually cost less to construct than comparable data centers and will be much cheaper to operate. NREL's approach was to minimize the energy needed, supply it as efficiently as possible, and then capture and reuse the heat generated.
"Compared to a typical data center, we may save $800,000 of operating expenses per year," Hammond said. "Because we are capturing and using waste heat, we may save another $200,000 that would otherwise be used to heat the building. So, we are looking at saving almost $1 million per year in operation costs for a data center that cost less to build than a typical data center."
Warm-Water Cooling Boosts Data Center Efficiency
The ultra-efficient HPC system in NREL's new data center has been designed in collaboration with HP and Intel. The HPC system will be deployed in two phases that will include scalable HP ProLiant SL230s and SL250s Generation 8 (Gen8) servers based on eight-core Intel Xeon E5-2670 processors as well as the next generation of servers using future 22nm Ivy Bridge architecture-based Intel Xeon processors and Intel Many Integrated Core architecture-based Intel Xeon Phi coprocessors. The first phase of the HPC installation began in November 2012, and the system will reach petascale capacity in the summer of 2013.
In the spirit of overall energy efficiency, the Intel Xeon Phi coprocessor delivers on several fronts. According to Intel, it can easily port complete applications in a short time, so software engineers won't need specialized tools or new languages to support significant software packages. "Intel coprocessors also increase the efficiency of computer resource usage," said Stephen Wheat, general manager of high performance computing at Intel. "The methods of code optimization for Xeon Phi are identical to what one does to make the most of Xeon processors. Finely tuned optimizations for Xeon Phi almost always result in a better-performing source code for Xeon processors. As the optimized and tuned application is run in production, the achieved performance per watt on both Xeon Phi and Xeon processors allows achieving the results with the lowest energy use."
While some of the NREL HPC components may be off the shelf, the team is taking a different approach in cooling this supercomputer.
"In traditional computer systems, you have a mechanical chiller outside that delivers cold water into the data center, where air-conditioning units blow cold air under a raised floor to try to keep computer components from overheating," Hammond said. "From a data center perspective, that's not very efficient; it's like putting your beverage on your kitchen table and then going outside to turn up the air conditioner to get your drink cold."

President Obama invited Yityish Aynaw, the first black Israeli to be named?Miss Israel,?to join him and the prime minister for a meal. Her success is a victory for long marginalized Ethiopian-Israelis.
By Ryan Lenora Brown,?Correspondent / March 14, 2013
A Palestinian woman walks past posters showing President Obama in the West Bank city of Ramallah, Tuesday. Obama's trip to Jerusalem and the West Bank, which Israeli officials say will take place next week, is the US leader's first trip to the region as president, and his first overseas trip since being reelected.

In a 48-hour trip to Israel next week, President Obama will tick off the usual diplomatic visit boxes: meeting diplomats and visiting the country?s historic sites.

And then he will have dinner with a beauty queen.
Obama?s staff personally invited the newly crowned Miss Israel, Yityish Aynaw ? who is the first black Israeli to the hold the title ? to a dinner at the home of President Shimon Peres next Thursday, a symbolic nod, perhaps, to the country?s 120,000 Ethiopian Jews, a community that has long faced?discrimination?in Israel.
Ms. Aynaw, who was crowned last month and will represent Israel at this year?s Miss Earth pageant, has already dazzled the Israeli press with the narrative of her hardscrabble childhood and rags-to-riches rise to beauty-queen stardom ? and is now making the rounds in international outlets as well.
"Ten years ago I was walking around barefoot in Ethiopia,? she?told Israeli news site Ynet News?yesterday. ?I never imagined that one day I would be in the land of Israel, meeting the Israeli president and the president of the United States. I could never have imagined such a powerful and exciting situation."
Born near the town of Gondar in northwestern Ethiopia, Aynaw was an orphan by age 10, and immigrated to Israel two years later to live with her grandparents. By the time she was 19, she?d become fluent in Hebrew, won a national student film competition, and was training to be a military police commander in the Israel Defense Forces (IDF).
Aynaw eventually led a cadre of guards, whom she trained to fire guns, man security checkpoints, and find bombs, according to?a profile in Tablet, a US-based Jewish magazine.
?I taught them to be human,? Aynaw said of her soldiers, who checked Palestinians driving through military checkpoints. ?My soldiers would ask, ?How can I be so nice when there were instances of a 9-year-old kid or a pregnant woman blowing themselves up at a checkpoint?? ? She?d tell them: ?There are many Palestinians who have a wife waiting at home, a family waiting for dad to bring bread home.?
Aynaw has offered other hints of her politics as well. She?told an Israeli news station?that she hoped to ask President Obama to release Jonathan Pollard, an American Jew who is currently serving out a life sentence for spying on the US for Israel.
And when a reporter told her that American beauty queens often tout their hopes for ?world peace,? she shot back, ?to say a sentence like that, in my opinion, is to sound retarded.?
?Iran is trying to develop a nuclear weapon, China is trying to become a superpower,? she continued. ?To say that I want world peace, of course I want it. It?s a dream. But I don?t think it will happen now.?
Ethiopian Jews have a checkered history in Israel. A series of dramatic airlifts in the 1980s and 1990s by the Israeli government brought thousands to the Jewish state, but they, their children, and subsequent waves of African immigrants have faced a hostile ? and at times overtly racist ? reception.
Today, the average income of an Ethiopian Israeli is?half that of Israelis at large, and more than half of employers surveyed in 2010 said they would prefer not to hire an Ethiopian. In January, the Israeli state copped to giving a number of Ethiopian women in Israel long-term birth control shots without their consent.
Aynaw has walked into that fray with diplomatic beauty-queen aplomb.
"It's important that a member of the Ethiopian community win the competition for the first time,? she told a judging panel during the Miss Israel competition. ?There are many different communities of many different colors in Israel, and it's important to show that to the world."
As the Tablet profile notes, however, Aynaw is not the first politically charged pick for Miss Israel. Israeli beauty pageants, he writes, have long been a powerful lens for understanding the image Israel wants to project to the world.
In 1952, at the height of tensions between Israel?s European veterans and Middle Eastern Jewish newcomers, Yemen-born Ora Vered became the first Miss Israel of Middle Eastern Jewish descent. In 1993, in the midst of Israel?s tidal wave of Soviet immigration, Kiev-born Jana Khodriker won, and in 1999, the peak of Israel?s optimism that Arab-Israeli peace was imminent, judges crowned Rana Raslan the first Arab Miss Israel.
Now, Israeli diplomats seem intent on building similar goodwill with Aynaw. Leo Vinovezky, Israel's deputy ambassador to Ethiopia,?told an Israeli newspaper?last week that ?this is the Ethiopian Jewry's finest hour."?
Aynaw will have her own shot at diplomacy of sorts when she competes in the Miss Earth pageant later this year: The competition will take place in Indonesia, a country with which Israel has no formal diplomatic ties.?

(AP Photo/Dave Martin)
NASHVILLE, Tenn. (AP) ? The Mississippi Rebels now have two very big items on their resume that nobody can take away.
Murphy Holloway scored 23 points and Marshall Henderson had 21 as the Rebels gave coach Andy Kennedy his first NCAA tournament berth by upsetting 13th-ranked Florida 66-63 on Sunday for the Southeastern Conference tournament championship.
"So much is made about the NCAA tournament," Kennedy said. "I was just glad to get the albatross that is the NCAA tournament off the neck of our program so people can now exhale and get a new focal point."
The Rebels (26-8) have won seven of eight grabbing their first tournament title since 1981 and their second ever. Even though they thought reaching this game for the first time since 2001 probably clinched their seventh NCAA bid in Kennedy's seventh season as coach, the Rebels wanted the SEC championship too.
"We worked so hard to get to this point, and it just feels so good to celebrate with the guys in the locker room," Rebels senior guard Nick Williams said. "I don't know man. I'm at a loss for words."
Reginald Buckner added 13 points for Ole Miss, which won two straight without point guard Jarvis Summers. The sophomore suffered a concussion in Friday night's 64-62 win over Missouri. That forced Kennedy to use Ladarius White, while Henderson and freshman Derrick Millinghaus also handled the ball.
"Can you imagine going into a game of this magnitude with a backup quarterback?" Kennedy said. "And that's what this team had to do."
Florida (26-7) hasn't won this tournament since wrapping up a three-peat in 2007, and the Gators lost to Kentucky in this game two years go. The SEC regular season champs still haven't won a game by fewer than 10 points this season. They go into the NCAA tournament 0-6 in games decided by six points or less.
"The people trying to create this drama around a situation that's not necessarily true," Florida coach Billy Donovan said. "Our guys haven't lost confidence at all. They dug themselves a hole with our lack of defense. ... The truth of the matter is we were up 12 and allowed Ole Miss to shoot 53 percent in the second half and we shot 29 percent."
The Gators had a final chance to force overtime. Scottie Wilbekin missed two free throws with 4.2 seconds left, and Kenny Boynton's last gasp 3 glanced off the rim after he took a step back to make sure he was over the line.
"I kind of rushed it because I was trying to back up and make sure it was a 3-point shot before time ran out," Boynton said.
Mike Rosario had 18 points and Boynton added 13 for the Gators.
Ole Miss outshot the regular season champs 47.4 percent (27 of 57) compared to 37.3 percent (22 of 59) and outrebounded them 37-34. That gave the Rebels an 11-5 edge on second-chance points. The Gators struggled at the free throw line, making 3 of 11 there in the second half. They missed their final five attempts over the last 4:19.
Florida came in third nationally holding opponents to 52.3 points a game, while Ole Miss is the sixth-best scoring offense in the country with 78.7 points a game.
"The frustrating part for me was just our defense because we clearly have been one of the better defensive teams all year long," Donovan said.
Florida led 38-26 at halftime after hitting 7 of 14 3-pointers, taking advantage of Henderson hitting just 1 of 6 from the floor with three points.
The Rebels opened the second half on a 10-3 run to get back into the game. The Gators missed eight of their first 10 shots in the half, and Henderson found Buckner for a dunk with 13:39 left that tied it up for the first time at 43. The teams swapped the lead with the Gators using seven straight points to go up 53-52 on a 3-pointer by Murphy.
Then Williams hit a jumper, Henderson scored on a driving layup, and Henderson knocked down another 3 off a miss by Williams when Buckner poked the ball out to the feisty guard, putting Ole Miss up 59-53 with 7:15 left. Henderson celebrated by doing the gator chomp at Florida fans before heading to the bench for a timeout.
Henderson was named the tournament MVP after being snubbed by league coaches for the All-SEC first team earlier in the week.
"They didn't win this tournament. We did," Henderson said. "We went in with a chip on our shoulder. Maybe they'll be smarter next year."
The Gators got within two points twice down the stretch, the last at 65-63 when Rosario drove to the basket for a layup with 35.4 seconds left. Casey Prather stole the ball from Henderson with 22.3 seconds left, and Donovan called a timeout.
Erik Murphy missed an 8-foot jump hook over Buckner with less than 10 seconds left, and Holloway grabbed his 10th rebound and was fouled immediately. He hit a free throw with 8.6 seconds remaining for the final margin setting up the Gators' last chance.
"I was just like, 'Man, just make one. Just make one just in case they hit a 3 we can go into overtime,'" Holloway recalled. "Me and my boy Reg been struggling, ever since we got here, we've been struggling. I knew I had to step up. So I stepped up. I made one."

It may be harder nowadays to dazzle audiences with fancy visual effects, but Monsters, Inc. 3D proves that smart, imaginative storytelling still does the trick every time.
Most of the charm of "Monsters Inc." comes from its vocal cast.
If history is any guide, you and your family - whether young or old - will probably want to see "Monsters University" over and over.
The movie itself stands up well, even from an adult, two-dimensional perspective.
Its reassuring message is more relevant than ever.
The good guys are those who realize that laughter is stronger than fear. That's a message worth taking to heart these jittery days.
Pixar's overlooked gem arrives in a worthwhile collector's edition bursting with features and exceptional A/V presentation.
While nippers will love the colourful creatures and their slapstick antics, grown-ups will find less humour and layers than in the likes of Toy Story, meaning less overall appeal as a result.
[I] really don't see the point of paying extra for children under eight. Their eyes are still developing, their noses are still small for slippery glasses, and... isn't a trip to the pictures enough for them in any case?
If anything, it improves with age.
Monsters displays wonderful imagination which makes it worth reliving in an extra dimension - particularly the energetic chase scene along a conveyor belt of doors.
Pixar's soaringly lovely fourth feature ...
[An] exciting, imaginative and very likable adventure.
Despite its eternal message about physical differences and the importance of love over fear of the unknown, Monsters, Inc primarily remains an ambitious concept film.
It's in the visuals that 'Monsters Inc' comes to life, from the jazzy, Norman McLaren influenced opening to the hilarious, shakycam amateur-dramatic recap over the closing credits.
Another chance to see Pixar's most dazzling premise, now spruced up with a third dimension.
Now in 3D, the filmmakers have created a wonderful reality - the reality of Monstropolis, which like the worlds of Oz and Pleasantville, whisk us far, far away on a magic carpet of fantasy
A shrewdly timed reminder of Pixar's early, heady days, when the animation powerhouse could do no wrong.
This didn't need 3D to work. It long ago passed the kids-wear-out-the-DVD-rewatching-it test.
There's really little reason to check out Monsters, Inc. 3D in... well, 3D, rather than going for a good old-fashioned 2D screening instead.
It does well, but not brilliantly: an amusing trifle from a studio whose best work still lay ahead of it.
Not quite a Pixar classic, but funny, witty and visually spectacular enough to be enjoyed again on the big screen.
Monsters, Inc. continues a positive 3D trend for the company, who appear to be selecting their upgraded titles wisely, choosing features that benefit from the additional depth.
Not even the opportunistic 3D-ification can squander the pure delight of the film's meticulously detailed world of ragtag creatures.

Fivetran, a new Y Combinator-backed startup that is launching today, wants to bring spreadsheets into the modern age and make it easier for users to work with messy data and analyze large amounts of information. Most people, for better or worse, use their spreadsheets as databases, and Fivetran acknowledges this by combining SQL-like queries with standard spreadsheet functions and statistical tools that will look familiar to users of more advanced tools like Matlab. As the co-founders George Fraser (CEO) and?Taylor Brown (head of product) told me earlier this week, the idea behind the project is that “spreadsheets have 50 percent of the power of programming and we want to bring the other 50 percent to spreadsheets.” As the founders told me, there is still a huge gulf between tools like Excel and Matlab. The earliest prototypes of Fivetran still leaned more toward the Matlab side of things and looked more like a programming environment. Today, however, the service is more like a regular spreadsheet with extensive wizards that guide you through complex data transformations (including regression models) and the SQL-like selects and joins, as well as the tools data cleaning and text-mining features. Because the calculations happen in the cloud (on Amazon’s EC2 platform), spreadsheets can be extremely large and complex. The service, which the team started working on last December, allows users to upload Excel documents, as well as CSV and JSON files and start working with them immediately (in the long run, the team plans to add direct connections to databases, too). To give people a better idea of the power of Fivetran, the founders also created a March Madness bracket simulator, as well as a set of tutorials. Once they have added their initial data, users can manipulate it using Fivetran’s “step” system, which allows them to create additional sheets based on their calculations. This is a bit of a departure from how most spreadsheets work, but you can also still use your familiar Excel formulas (think SUM(a,b) etc.) to work with your data as well. The team is currently working on adding unit testing and a revision control system for spreadsheets. Fivetran is using an interesting pricing model that is a bit similar to what you would expect from a hosting provider. There are free accounts that allow you to create up to five projects that can use up to 1GB of memory. Basic accounts start
