Dell sells simulation supercomputer

Dell has sold a 128-server Linux cluster to the University of Utah's Center for the Simulation of Accidental Fires and Explosions for research into explosive scenarios such as jet crashes, the company plans to announce Wednesday. The deal involves 128 Dell PoweEdge 2650 servers with Intel Xeon processors and Red Hat's version of Linux, but the company declined to list terms of the deal.
