Subject Re: Scheduler - Partitioning
Date Thu, 30 Jul 2009 17:19:22 GMT
Hi,

The cluster is shared - any given node might be running tasks from any
number of distinct jobs. As new slots open up (regardless of node location)
they are assigned to the job that is under its fair share (at least speaking
for the fairshare scheduler)
