UIUC - CS 433 IBM Power7

The IBM Power7, released in February 2010, is a significant advancement from its predecessor, the Power6. With clock rates ranging from 2.4 GHz to 4.25 GHz and built on a 45 nm feature size, the Power7 architecture supports Power ISA v.2.06. It features up to 8 cores and multiple cache levels (L1, L2, L3), optimizing performance for a variety of applications. Funded by a DARPA contract, Power7 was initially intended for petascale supercomputing projects. Though some efforts, like the Blue Waters system, faced challenges, Power7 remains pivotal in high-performance computing.

  1. Adam Kunk Anil John Pete Bohman UIUC - CS 433 IBM Power7

  2. Quick Facts • Released by IBM in 2010 (~ February) • Successor of the Power6 • Clock Rate: 2.4 GHz - 4.25 GHz • Feature size: 45 nm • ISA: Power ISA v 2.06 • Cores: 4, 6, 8 • Cache: L1, L2, L3 References: [1]

  3. Why the Power7? • PERCS – Productive, Easy-to-use, Reliable Computer System • DARPA funded contract that IBM won in order to develop the Power7 ($244 million contract, 2006) • Contract was to develop a petascale supercomputer architecture before 2011 in the HPCS (High Performance Computing Systems) project. • IBM, Cray, and Sun Microsystems received HPCS grant for Phase II. • IBM was chosen for Phase III in 2006. References: [1], [2]

  4. Blue Waters • Side note: • The Blue Waters system was meant to be the first supercomputer using PERCS technology. • But, the contract was cancelled (cost and complexity).
