For the first time ever, a supercomputer using Nvidia chips has achieved a spot on the Top 500 list of the world’s fastest supercomputers. The Nvidia-containing machine is ranked No. 29 on the list that was released late Friday; it’s a cluster built by NEC and Sun Microsystems that uses chips from Nvidia, Intel and AMD. As Nvidia and AMD, which bought graphics chipmaker ATI in 2005, push graphics processors for scientific computing, this is a big milestone. The rest of the list was pretty anticlimactic, with IBM’s Roadrunner computer narrowly beating Cray’s Jaguar computer to stay on top of the twice-annual Top 500 list. Both machines are petaflop computers, meaning they can achieve a quadrillion floating point operations a second — a record that was broken by Roadrunner back in June.

The Top 500 organization has put out its twice-annual list of the fastest supercomputers, and there are few surprises. Roadrunner, IBM’s mammoth supercomputer that broke the petaflop record, holds the top spot. Big Blue is also the source of the lion’s share of the computers on the list, at 210, or 42 percent of the […]
