Re: [HTCondor-users] how to limit number of cores for condor to use per machine

["Glowka, Mark T (CTO Technology)" <mark.glowka@xxxxxxxxxxxxxxx>]

Use the following in your condor_config file:

 

NUM_CPUS = N

where N = the number of cpus or cores that you want HTcondor to use.

Subject: [HTCondor-users] how to limit number of cores for condor to use per machine

 

Hello! Is there a way to tell condor to not use more than N cores per machine (with more than N cores available) to execute a particular set of jobs? The actual problem is that each of my jobs requires a lot of memory, so to get a better throughout it probably makes sense to prevent condor from executing more than so and so many jobs on different cores of the same machine because then all of the machine's memory will be exhausted, causing the jobs to use the harddrive which is much much slower.

Thanks much,

Alex
