Use of large memory compute nodes on NIH Biowulf (Biowulf)

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 staff@biowulf.nih.gov with any questions or concerns
about the use of large-memory nodes.
