Another Linux supercomputer cluster with Advanced Micro Devices Opteron chip is in the works, this time for Los Alamos National Laboratory's nuclear weapons testing program.

Linux Networx has been selected to build the cluster of 1,408 dual-processor Opteron servers, it announced yesterday. The system, known as ‘Lightning’, will deliver theoretical peak performance of 11.26 trillion FLOPS (floating-point operations per second), the company said.

The deal is worth US$10 million, and Linux Networx expects to complete the system in September, said Dean Hutchings, company chief operating officer.

When completed, Lightning will rank slightly ahead of the MCR system the company built for Lawrence Livermore National Laboratories using Intel’s Xeon processors and Linux, according to the Top 500 list of the world's fastest supercomputers.
