Virginia Tech today announced that its rebuilt “System X” supercomputer cluster, which consists of 1,100 Xserve G5s, is now operating at 12.25 teraflops–an increase of almost two teraflops over the original system’s 10.28 teraflops. “Virginia Tech will learn of its new ranking when the list is unveiled in November of this year at SuperComputing 2004 in Pittsburgh,” said Srinidhi Varadarajan, the lead designer of the system. “We expect to do well.” Last year, the university’s system ranked third among the world’s 500 fastest supercomputers.
