[HTCondor-users] cpu affinity

[stefan harjes <stefanharjes@xxxxxxxx>]

Hi,

I run lots of vanilla jobs, where I request 4 cpus. When the four cpus are claimed my process can only use them when the ENFORCE_CPU_AFFINITY flag is set to False. If it is set to True, my jobs only use one cpu even though 4 cpus are claimed.

From my understanding cpu affinity would mean that the process can not claim more cpu resources than claimed, but in my case the process is always restricted to one cpu. I have observed this on linux and windows with version 8.25 through 8.27.

Any hints?

Thanks

Stefan
