In 2003, Virginia Tech's Terascale Computing Facility made national news for building the third-fastest supercomputer in the world. What made the news was not that that it was fast, but the way in which it was built. It was assembled from 1,100 ordinary off-the-shelf desktop computers (Apple Power Mac G5), networked via Infiniband technology. The result was an extraordinarily cost-effective system: Virginia Tech's 10-teraflop "Big Mac" cost $5.2 million; by comparison, the then-record-holding 35-teraflop Earth Simulator cost an estimated $350 million.<ref>[http://www.wired.com/science/discoveries/news/2003/11/61252 Mac Supercomputer Joins Elite], Wired, November 15, 2003</ref> | In 2003, Virginia Tech's Terascale Computing Facility made national news for building the third-fastest supercomputer in the world.
