|I have been working with CR to get a patch in maui and moab to improve trea=
|tment of vmem. The patch is in maui-3.2.6p21-snap.1234905291 and will be i=
|n upcoming moab releases. Many thanks to Brian Christiansen at CR.
|With the patch, maui/moab correctly detects a node's available vmem as bein=
|g the total physical memory plus swap space. This can then be scheduled/al=
|located by requesting vmem and job's virtual memory allocation can be limit=
|ed on a per process basis and periodically measured (and action taken or ov=
|eruse) on a per job basis.
Can such checking and action be done on pmem
as well, or just on vmem? We have some jobs
that need one, some the other.
