Sandia winners include:
"I congratulate the researchers who have won these awards, which highlight the power and promise of DOE's investments in science and technology," Secretary of Energy Samuel W. Bodman said. "Through the efforts of dedicated and innovative scientists and engineers at our national laboratories, DOE is helping to enhance our nation's energy, economic and national security."
Sandia is a National Nuclear Security Administration laboratory.
Compute Process Allocator (CPA)
The CPA's principal application is to maximize throughput on massively parallel supercomputers by managing how processors are assigned to particular computing jobs, given a stream of computing jobs submitted to a job queue. The CPA assigns each job to a set of processors, which are exclusively dedicated to the job until completion. The CPA obtains maximum throughput by choosing processors for a job that are physically near each other, minimizing communication and bandwidth inefficiencies.
In experiments at Sandia, the optimized node allocation strategy employed by CPA increased throughput by 23 percent, in effect, processing five jobs in the time it normally took to process four.
The CPA is scalable to tens of thousands of processors and is currently being used on supercomputers at Sandia (Red Storm), Oak Ridge National Laboratory, Engineer Research and Development Center Major Shared Resource Center, Pittsburgh Supercomputing Center, and the Swiss Scientific Computing Center.
Solid-state fluoride ion batteries have nearly the same energy density of lithium sulfuryl batteries while being inherently safe. The battery consists of nontoxic fluoride, and all three battery components of the HTSS10V - anode, cathode, and ionic conductor - are solid, making it the best and safest choice for high-temperature activities such as oil and gas drilling, currently its primary application. Traditional lithium batteries are at risk of exploding or leaking chemicals under high-temperature uses. Solid-state battery technology offers the largest temperature range - room temperature to 500 degrees Celsius - of any battery technology.
Other advantages of solid-state batteries include:
Researchers are currently working on a rechargeable version for laptop computers.
Limited production of the batteries began in 2005 at Russia's VNIIEF Institute. Under a joint program with Sandia and General Atomics, the batteries will be produced in Sarov, Russia, and in San Diego, Calif., for high-end oil and gas drilling uses.
Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin company, for the U.S. Department of Energy's National Nuclear Security Administration. With main facilities in Albuquerque, N.M., and Livermore, Calif., Sandia has major R&D responsibilities in national security, energy and environmental technologies, and economic competitiveness.
