: IBM to Build DOE Supercomputers "> ASCIfor the DOEs Advanced Simulation and Computing InitiativePurple will run about eight times faster than the last supercomputer IBM built for the DOE, in 2001, and will work at a speed close to that of the human brain, IBM said. It will reach a peak speed of 100 teraflops, or trillions of calculations per second. It will be a massive cluster of IBM eServers and storage systems powered by 12,544 Power5 microprocessors. The chips will be contained in 196 individual computers, linked together via an interconnect with a bandwidth of 12,500GB. It will run IBMs AIXL operating system and hold 50TB of memory. ASCI Purple will enable the DOEs Lawrence Livermore laboratory to simulate nuclear weapons explosions without having to actually detonate any test weapons, according to IBM.Both computers will contain self-healing, autonomic features, such as the ability to reroute work around a failing chip and reassign work within the computer depending on demand, IBMs Arimilli said.
The Blue Gene/L will have a peak performance of 360 teraflops with 130,000 chips for use at the DOEs Sandia, Los Alamos and Lawrence Livermore labs. It will be used for massive calculations in areas such as life sciences and global climate change.
