ThinkSecret provides some confirmation on earlier rumors that Virginia Tech will be migrating from PowerMac G5s to Xserve G5s in their recently assembled Supercomputer cluster. MacRumors has also received multiple confirmations of the planned upgrade, but varying reports as to the fate of the original PowerMacs used in the cluster. According to ThinkSecret, Apple will be providing a one-to-one tradein for the PowerMacs with Xserves. As one reader (suzerain) noted, Srinidhi Varadarajan had stated in October that "We are planning on moving to ECC systems in the future", suggesting that the upgrade has been planned for some time. Apple's recently released Xserve G5s support ECC memory, while the PowerMac G5s do not.
