Hi All,

In our SGE cluster, we have 2 nodes each of 4 CPU's and we are using "fill up host" scheduler configuration for job submission.

In this scheduler configuration, assume one parallel job (Job1) with 2 CPU's is running on nodeA and user submits another parallel job (Job2) of 2 CPU then SGE submit this job2 on nodeA.

Consider if the Job1 is utilizing higher memory on nodeA then job2 fails due to memory unavailability.

Is there a way to avoid this using SGE configuration?

Any help for this issue will be appreciated.

Already we used "use least used host first" scheduler configuration in this case when user submits two jobs say JobA(2 CPU) and JobB(2 CPU) it occupies nodeA(2 CPU) and nodeB(2 CPU). If user submits another parallel job of 4 CPU then it will be in waiting queue. So we moved to "fill up host" algorithm.
