- POWER7
POWER7 is a
microprocessor currently under development at about a dozenIBM sites includingIBM 's Rochester, Austin and Böblingen laboratories as of April 2006.The POWER7 is the successor toPOWER6 and is slated for a 2010 release [http://www.theregister.co.uk/2008/07/11/ibm_power7_ncsa/] .History
IBM won a $244 million
DARPA contract in November 2006 to develop a multi-petaFLOPSsupercomputer architecture before the end of 2010. The contract also states that the architecture shall be available commercially. IBM's proposal, PERCS (Productive, Easy-to-use, Reliable Computer System), which won them the contract, is based on the POWER7 processor, AIX operating system and General Parallel File System.cite web |title=Cray, IBM picked for U.S. petaflop computer effort |publisher= [http://www.eetimes.com/ EETimes.com] |url=http://www.eetimes.com/news/latest/showArticle.jhtml;jsessionid=3ZYLXC1ZK5OPMQSNDLSCKHA?articleID=195800001 |accessdate=2006-11-22 ] See also HPCS.Although it has been suggested that POWER7 and future AMD Opteron processors will share
CPU socket layout, that convergence has never been confirmed by either IBM or AMD.

The Register [http://www.theregister.co.uk/2008/07/11/ibm_power7_ncsa/] reports that POWER7 will have these specifications.
*45 nm process
*2 chips per module
**8 cores per chip
***4 threads per core (32 threads per chip)
*4.0 GHz clock speed
*256GFLOPS per chipOther features include 2U servers with 4 modules per server (2
TFLOPS ) and 128 GB RAM support, and a large unit comprised of multiple 2U servers consisting of 1024 cores (32 TFLOPS) and up to 2 TB RAM.See also
