NASA's Pleiades Supercomputer Ranks Among World's Fastest
See Full NASA Release
Excerpt: WASHINGTON -- NASA's largest supercomputer is seventh on the TOP500 list of the world's most powerful, high-performance computers. The announcement was made at the 26th International Supercomputing Conference in Hamburg, Germany.
Pleiades, located at NASA's Ames Research Center in Moffett Field, Calif., supports more than 1,000 active users around the country who are advancing our knowledge about the Earth, solar system and the universe....
"We're really excited that Pleiades delivered nearly 83 percent of the theoretical peak performance," said Rupak Biswas, chief of the NASA Advanced Supercomputing (NAS) Division at Ames. "This means our science and engineering users get extremely efficient use of their computing time on the system. Reaching the sustained petaflop per second rate is a significant milestone for NASA and its industry partners."
...Pleiades now contains 23,296 Intel(R) Xeon(R) quad- and hex-core processors (111,104 cores in 182 racks) that can run at a theoretical peak of approximately 1.32 quadrillion floating point operations, or calculations, per second. It achieved an official sustained rate of 1.09 petaflop per second using the LINPACK benchmark, the industry standard for measuring a system's floating point computing power....
