Linux clusters to model HIV and weapons

Los Alamos National Laboratory has ordered two Linux clusters, one for modeling nuclear weapons and the other for unclassified research in biology, chemistry and engineering.

Linux Networx Inc. of Bluffdale, Utah, will build a 1,408-node cluster, dubbed Lightning, for the Energy Department's Advanced Simulation and Computing program and a 256-node cluster, called Orange, for the lab's Institutional Computing project.

Each node will have two 64-bit Opteron processors from Advanced Micro Devices Inc. of Sunnyvale, Calif. Linux Networx officials predicted Lightning's theoretical peak will reach 11.26 trillion operations per second.

The 256-node Orange cluster will use InfiniBand switched-fabric interconnect technology from Mellanox Technologies Ltd. of Santa Clara, Calif., Daines said.
