Submission + - IBM supercomputer dual boots Windows and Linux
Stony Stevenson writes: IBM has built the biggest ever dual-boot Windows/Linux HPC system for a consortium of Swedish research groups and universities. The record-chasing firm will apparently unveil its 5,376 Intel Xeon quad-core processor blade system later on today. The system is able to reach an impressive 46 sustained teraflops on a beta version of Windows HPC Server 2008, with each chip apparently running at 2.5GHz and using 50 watts. What makes the achievement particularly noteworthy is the fact that it is a relative rarity for an HPC system to be built on Windows rather than exclusively on Linux, which makes up around 85 percent of all HPC systems in the world.
