CACR-hosted Theoretical AstroPhysics Cluster expands

The MRI2 cluster, meeting the application needs of Caltech’s Theoretical AstroPhysics Including Relativity (TAPIR) group, has expanded to include an additional 40 compute nodes. The configuration, integrated by Hewlett-Packard and CACR’s Operations team, now consists of 2016 Intel X5650 compute cores, in 168 dual Westmere hex-core nodes, equipped with ~ 4 TB of memory (2 GB/core). The cluster is connected by a 2:1 fat tree QDR InfiniBand network, with high speed access to 80 TB (usable) of high performance Panasas storage and 48 TB of archival storage. For more information about the system, see the CACR Facilities & Operations page.

The MRI2 cluster, called “zwicky”, provides compute and storage resources for research codes investigating core-collapse supernovae, gamma-ray bursts, black holes and neutron stars.
