Hi.

I am using SGE 8.1.2 with several queues and recently, several of my 64-slots queues are not scheduling the full 64-cores.

So if I submit 64 1-core jobs, only 57 or so are schedule per node instead of 64.      If I submit 4 16-core pe jobs, only 3 of the 16-core pe jobs are scheduled on a node instead of 4 ( 16x4 = 64 ).

This was working before just fine, so I think SGE just lost track or something.    I tried restarting SGE with same symptoms.    My queues do show "slots=64".    The compute nodes do not have any special settings.

Is there a way to tell SGE to re-count cores per node, or to reset SGE without disrupting running jobs?

Joseph
