Panasas powers fastest supercomputer in the world
posted on 09 June 2008 07:17
The world's fastest supercomputer, Roadrunner, rated at 1.026 petaflops, uses Panasas clustered parallel access storage to keep its 116,640 processor cores busy.
A petaflop is one thousand trillion floating point operations per second and Roadrunner achieves this with 12,960 IBM/Toshiba cell-type Broadband Engine processing chips, originally designed for video games, and a substantial number of AMD Opterons. The machine, based at the Los Alamos National Laboratory (LANL), New Mexico, cost $133 million and will be used for simulations of nuclear weapons explosions and climate change modeling.
Twenty six Voltaire Grid Director 2101 switches are used in the Roadrunner supercomputer as the interconnect. Such switches feature up to 288 ports of 20Gbit/s InfiniBand connectivity.
The previous top supercomputer was IBM's BlueGene/L at the Lawrence Livermore National Laboratory in California.
