Linux Networx, who I wrote about last February has closed two deals with Los Alamos to build Linux supercomputer clusters for use in nuclear weapons simulations. The larger cluster will have a theoretical peak performance of 11.26 teraflops per second and use 2,816 Opteron processors. I toured their facility before they moved and thought that it looked like a hardware guru's dream. According to the article in TechNewsWorld, the cluster will be delivered in 2 months---a record delivery time compared to the typical two-year delivery time for a supercomputer. Linux Networx makes news selling these multi-thousand processor clusters, but their bread and butter is smaller clusters for more typical business needs.
