1. IBM 1350 Cluster Expansion Doug Johnson Senior Systems Developer

2. Statewide Users Group: Mar 13, 2008 2 Recommendation Summary Expand the existing IBM E1350 cluster with a BioSciences focus: The proposed expansion, while compatible with our existing system, will have features that form a good fit for Biosciences Proposed expansion would propel the system ’ s rank to 4th in U.S. academic supercomputing centers System would be ranked 21st in the overall Top 500 Will provide researchers with a total of 59TF peak performance Increased memory from 8.4TB to 17.5TB –Add 240TB of integrated storage System will be set up for dynamic changes in the operating environment to benefit innovation by the biosciences community The system will also be suited to many other applications and will fit into our current environment including staff knowledge and capacity

3. Statewide Users Group: Mar 13, 2008 3 Glenn Cluster Upgrade - Upgrade Details The cluster expansion will add approximately 500 nodes. –2 quad-core CPUs per system, 2.3 GHz likely clock speed –16/24 GB memory (24 GB in ~1/3 of the systems.) –20 Gbit/sec IB network –1 Gigabit Ethernet –5 00 GB or larger internal disk drive There will also be approximately 5 larger memory systems with a total of 16 processor cores and 64 GB of memory. Newer versions of hardware for the IB network will deliver 20 Gb/sec throughput to each cluster node, with a communication latency that is less than half compared to the existing network. The newer generation of IB network will integrate with the existing network. This will allow parallel applications to be run across the new and existing nodes.
