Power 775 (supercomputing)
Encyclopedia
The Power 775 is a supercomputing component from IBM Corporation.
Formerly known as the POWER7 IH, the Power 775 is part of the PERCS
(Productive, Easy-to-use, Reliable Computing System) - IBM's answer to DARPA's High Productivity Computing Systems
(HPCS) initiative. PERCS is based on POWER7
processor, X10 (programming language)
, AIX operating system and General Parallel File System.
The Power 775 was released by IBM in 2011 as a commercial product after IBM ended its participation in the Blue Waters
petaflops project at the University of Illinois, but marketed the 775 based on the growth of its high performance computing business.
with four POWER7 CPUs each, and 16 DDR3 SDRAM
slots per MCM for a total of 256 POWER7 cores and 2 TB RAM. Each drawer also has eight optical connect controller chips, connecting neighboring MCMs, PCIe peripherals and other compute nodes. One rack can house up to a dozen Power 775 drawers for a total performance of 96 TFLOPS.
Unlike the IBM Blue Gene
series which uses low-power processors to avoid heat density issues, the Power 775 is a water-cooled
system.
The system supports up to 24 terabytes of memory and 230 terabytes of storage per rack. It is estimated to achieve over 96 teraflops per rack.
