US lab building Opteron-based Linux supercomputer

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

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

The deal is worth US$10 million, and Linux Networx expects to complete the system in September, Dean Hutchings, COO of the company, says.

A number of Linux supercomputers have been announced over the past few weeks. Dell is working on what will become the fastest Linux supercomputer when it is finished later this year, with 17.7 trillion FLOPS of peak theoretical performance. IBM Corp. and Fujitsu Ltd. also are developing Linux supercomputers that will be deployed next year with TFLOPS results expected to be similar to that of the Linux Networx system.
