[HTCondor-users] Limiting number of jobs of specific user to N per node

[Sean Crosby <scrosby@xxxxxxxxxxxxxx>]

Hi all,

We run jobs for the Belle experiment, and at the moment, their jobs are very IO intensive. If say, on a 12 core node, if all 12 cores are taken up by Belle jobs, the node suffers heavily from IO problems.

We'd like to limit the number of belle jobs on each node to be (say e.g.) 4, but keep the other 8 slots to be open for other user jobs.

What's the easiest way to do this?

[root@rccondor ~]# rpm -qa | grep condor

condor-python-8.6.5-2.el7.x86_64

condor-classads-8.6.5-2.el7.x86_64

condor-procd-8.6.5-2.el7.x86_64

condor-8.6.5-2.el7.x86_64

condor-external-libs-8.6.5-2.el7.x86_64

Cheers,

Sean
