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+ processors with only a single core active.
Each processor core 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 processor cores
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 POWER5+
cluster node delivers substantially higher packaging density; compared to its
POWER5 predecessor, it delivers substantially higher sustained performance for
HPC applications.
