Computers May Negate Need for Nuclear Tests

By Matthew Harwood


The government will spend $26 million on high-end computers to cut costs and standardize systems among the three U.S. labs charged with ensuring the safety and reliability of the nation's aging nuclear stockpile.

The Energy Department's National Nuclear Security Administration (NNSA) awarded the multimillion-dollar contract to Milpitas, Calif.-based Appro to supply Lawrence Livermore, Los Alamos and Sandia national laboratories with 438 teraflop high-performance computing clusters based on the Quad-Core AMD Opteron processor. To date, each of these labs had used its own combination of computer systems, which were not always compatible with the others.

The computers will be used for nuclear testing simulations which will replace underground testing and extend the life of aging nuclear weapons.
