The BlueGene/L Supercomputer (Distinguished Seminar Series)
BlueGene/L is a massively parallel supercomputing project being carried out at IBM. Three initial installations are currently planned, the first at the Lawrence Livermore National Laboratories, the second at the IBM T.J. Watson Research Center and the third at the ASTRON research center in the Netherlands. These machines consist of tightly integrated components, combining standard POWER embedded processors with five independent networks and a custom memory subsystem. The largest of these systems will have over 130,000 processors and will have a peak performance of approximately 360 Teraflop/s. These systems run a full system software stack, featuring Linux, as well as standard compilers. We report on progress of this project, including sustaining performance in excess of 16Teraflop/s on a four rack system. We also discuss early experience in scaling real applications to these systems.
