Virginia Tech Upgrades to 2.3GHz Xserves
According to AppleInsider and a column at USA Today, the System X supercomputer at the Virginia Tech Terascale Computing Facility has been upgraded to Apple Xserve Dual G5s running at 2.3GHz, up from 2.0GHz.
The cluster consists of 1100 Apple Xserve G5s, each with 4 GB RAM, and was previously upgraded in January from Power Mac G5s to Xserves.
Apple still describes the Xserve G5 as running only up to 2.0GHz, although specs in a leaked graphic in January showed 2.3GHz. The 2.3GHz version was reportedly made available exclusively to Virginia Tech.
