Default Memory Reservation Added to Cluster

posted Apr 7, 2014, 5:42 PM by Grant Brady
We have set the default memory reservation to 1GB for the batch queue (nodes 1-34). If you do not specify otherwise, the cluster will now assume that your job only needs 1GB of RAM. You will need to make a specific reservation if your job needs more memory than 1GB or the cluster will automatically kill the job for resource violations. For information on making a reservation, please consult the cluster manual:

These changes have increase the stability of the cluster by preventing nodes from being over-allocated. This greatly reduces the chances of a node crashing. It will also help prevent cases where jobs run too slowly or not at all because they do not have the resources they need. If you can any questions about this, please contact us at
