Use of large memory compute nodes on NIH Biowulf (Biowulf)Date: 13 October 2010 12:10:01
From: steven fellini (sfellini@NIH.GOV)
Compute nodes with 72 GB of memory ("g72" nodes) are a limited resource on the Biowulf Cluster as there are only 32 of these nodes. The next expansion of the cluster will increase this number, but to ensure that these nodes are most efficiently utilized, it is vital that each user allocate nodes with appropriate memory for their jobs. It is inappropriate to allocate the "g72" nodes if a node with less memory (e.g. g24, g8, g4) is sufficient for your job. Effective immediately, jobs that have inappropriately allocated large-memory nodes while underutilizing the memory on those nodes are subject to termination by the Biowulf staff to allow jobs queued for those nodes to run. Details on monitoring memory usage are at http://biowulf.nih.gov/user_guide.html#mem_usage Please review this section of the user guide if you allocate large-memory nodes for your jobs. Please contact email@example.com with any questions or concerns about the use of large-memory nodes.
