How to scatter jobs over vnodes?

[adarsh]

Please share your pbsnodes -aSj and chunk submission line , what job placement string do you use ?

@rcole

Is there a required time-frame between job submissions?

No, there is no time frame, thousands of jobs are submitting within a minute for some usecases.

@rcole

I looked in the PBS Scheduler Config and saw “smp_cluster_dist” which seems exactly what I am trying to do, but it didn’t change the outcome.

smp_cluster_dist is deprecated. please check the PBS Pro administrator guide.

@rcole

have made the changes and still, when i submit jobs, they are still being scheduled more like the “pack” method, where one node gets filled up to capacity before jobs spill over to the next node.

Please check:
4.7 Specifying Job Placement in the PBS Professional User Guide https://www.altair.com/pdfs/pbsworks/PBSUserGuide19.2.3.pdf

and use the below node_sort_key
node_sort_key: “ncpus LOW assigned” ALL
