Power 7 Linux Cluster (P7)

February 27, 2012 in Systems

SciNet’s Power 7 (P7) cluster consists of 5 IBM Power 755 Servers each with 4x 8core 3.3GHz Power7 CPUs and 128GB Ram. Similar to the Power 6, but running Linux, the Power 7 utilizes Simultaneous Multi Threading (SMT), but extends the design from 2 threads per core to 4. This allows the 32 physical cores to support up to 128 threads which in many cases can lead to significant speedups.

A “quickstart” guide to running on SciNet’s P7 cluster is available on our technical documentation wiki.
