Hardware Changes on the NIH Biowulf Cluster (Biowulf)Date: 11 May 2010 15:05:49

Some significant changes to the Biowulf cluster will occur in the next few weeks: -- All 32-bit nodes will be retired on Tuesday May 25, 2010. The p2800 nodes have 32-bit Xeon processors and are the oldest nodes in the cluster at over 6-years old. After the p2800 nodes are retired, all compute nodes in the cluster will have 64-bit architectures making the "x86-64" PBS property unnecessary. Note that all existing 32-bit code will continue to run on the 64-bit nodes. -- Myrinet will also be retired on Tuesday May 25, 2010. Jobs requesting the "myr2k" property will no longer be accepted by the batch system. Applications requiring high-bandwidth, low-latency networks should use Infiniband instead of Myrinet. -- June 2010. 336 nodes (2688 cores) will be added to the cluster. The new compute nodes have two quad-core Intel Nehalem processors running at 2.67 Gz and 24 GB memory. Details on how to submit jobs to these nodes will be announced when the nodes are ready to come online.
