IBM p5 575 Cluster Node

The IBM System p5 575 cluster node is designed to excel at high performance computing (HPC) applications for organizations involved in engineering problem solving, drug design, oil reservoir modeling, weather forecasting, financial simulation and business intelligence (BI). Use it in clustered configurations of as few as 16 CPUs, or in world class supercomputer configurations of more than 2,000 processors.

The System p5 575 features a choice of two powerful nodes. An 8-core node includes dual-core 2.2 GHz POWER5+ microprocessors with only a single core active. Each processor has access to 1.9MB of L2 and 36MB of L3 dedicated cache for HPC and BI applications. Also available is a 16-core node built with dual-core 1.9 GHz chips that have both cores active. In this case, two processors share access to the same L2 and L3 cache. Although per processor cache and memory bandwidth are less, the 16-core node achieves up to 60% more floating-point performance1 for HPC applications than the 8-core node.

The p5-575 offers ultra-dense packaging; no other IBM POWER5™ processor-based system can match the extraordinary density achieved with nearly 200 CPUs in a single footprint (12 p5-575 16-core cluster nodes packaged in a single 24-inch system frame). Compared to its POWER4™ predecessor, the System p5 575 delivers substantially higher packaging density; compared to its POWER5 predecessor, it delivers substantially higher sustained performance for HPC applications.
