Additional Compute Nodes Added to NIH Biowulf Cluster (Biowulf)Date: 22 June 2010 12:06:23

The Biowulf Staff is pleased to announce the expansion of the NIH Biowulf cluster by 336 compute nodes (2688 processing cores). The nodes are configured with two Intel quad-core "Nehalem" processors running at 2.67 GHz (8 cores/node), 24 GB memory, gigabit ethernet and 200 GB local disk available as /scratch. Additionally, 16 nodes have been configured with 72 GB memory for a cluster-wide total of 32 nodes with 72 GB. The addition of these nodes brings the total number of processing cores in the Biowulf cluster to 9000. For users wishing to use these nodes to run 8-process parallel jobs, use the "c8" PBS property to allocate nodes with 8-cores. Running single node jobs on "ib" nodes is no longer permitted. For users wishing to use these nodes for their memory size, use the "g24" property. Since all nodes in the cluster are now 64-bit, the x86-64 property will be deprecated. Beginning JULY 21, specifying the x86-64 property to qsub will return an error.
