LLNL and weapons labs to receive computing clusters

Donald B Johnston, LLNL, (925) 423-4902, johnston19@llnl.gov




The Advanced Simulation and Computing program at the Laboratory will receive new "capacity" computing resources under a contract announced by the National Nuclear Security Administration (NNSA) Wednesday.

The new computers are part of a tri-lab procurement that also will benefit stockpile stewardship work at Sandia and Los Alamos national labs. The contract was awarded to Appro, a leading developer of high-performance Linux cluster computing systems based in Milpitas. LLNL led the tri-lab computing cluster (TLCC) procurement for NNSA.

The new clusters will support NNSA's Life Extension Program and investigations into technical issues related to aging weapons systems, efforts critical to ensuring the safety security and reliability of the nuclear weapons in the stockpile as they age well beyond their intended deployment life.

Under the terms of the contract, computing clusters built of "scalable units" (SUs) will be delivered to each of the laboratories between September 2011 and June 2012. Each scalable unit represents 50 teraFLOP/s (trillion floating operations per second) of computing power. These SUs are designed to be connected, much like Legos, to create more powerful systems. Scalable units will be divided among the three labs, with each configuring the SUs into clusters according to mission needs.

"Capacity" computing systems are designed to run a large number of jobs simultaneously on a single system.
