I have one pbs cluster which has two execution nodes and each of them has 4 pcpus.
I want to submit one simple job like "echo “sleep 60” and specify the job using 5 cpus. Then PBS can help me allocate the job to two nodes automatically.
My question is that:
Is there any way to do this? I just find something like “ncpu” which specify cpu for every node.
And I have tried using “echo “sleep 60” | qsub -l nodes=2 -l procs=10” but got the error that
“qsub: Unknown resource Resource_List.procs”. How do I fix this error?
You can create a queuejob hook, that has profile of the cores against nodes of your PBS Cluster qsub -l ncpus=5 -- /bin/sleep 1000 when submitted the queuejob hook will re-create the chunk statement as -l select=1:ncpus=4+1:ncpus=1
procs is a job wide custom resource as per your qsub statement. In order to fix it you should create a custom resource as below for the server to recognise qmgr -c "create resource procs type=long" and if you want the scheduler to recognise it , add it to the resources: "......, procs" in the sched_config file and kill -HUP <PID of pbs_sched daemon>
