With the addition of ten more racks of quad-core X5570 Nehalem processors in 2009, Pleiades ranked sixth on the November 2009 TOP500 with 14,080 processors running at 544 teraflops. It originally contained 100 SGI Altix ICE 8200EX racks with 12,800 Intel Xeon quad-core E5472 Harpertown processors connected with more than 20 miles of InfiniBand double data rate (DDR) cabling. History Īnatomy of a Pleiades node, shown on display at the NASA Ames Exploration Center, in Mountain View, Californiaīuilt in 2008 and named for the Pleiades open star cluster, the supercomputer debuted as the third most powerful supercomputer in the world at 487 teraflops. The system serves as NASA's largest supercomputing resource, supporting missions in aeronautics, human spaceflight, astrophysics, and Earth science. It is maintained by NASA and partners Hewlett Packard Enterprise (formerly Silicon Graphics International) and Intel.Īs of November 2019 it is ranked the 32nd most powerful computer on the TOP500 list with a LINPACK rating of 5.95 petaflops (5.95 quadrillion floating point operations per second) and a peak performance of 7.09 petaflops from its most recent hardware upgrade.
