Re: [HTCondor-users] Reserve Cpus support in HTCondor

[Vikrant Aggarwal <ervikrant06@xxxxxxxxx>]

Hello Raman,

You may try to set the CPUAffinity setting in condor systemd service to exclude the cores reserved for weka filesystem and core 0 for system.Â

Thanks & Regards,

Hi all,

Is there any support in HTCondor to reserve Cpu0 and not to use it?

As then I can isolate all cpus for performance and update all interrupts and other stuff to Cpu0?

I am also experimenting with weka filesystem and it uses 1-2 cores of each machine it is mounted on, so just want to know is there way to do this?

I am using htcondor vanialla universe

Thanks and RegardsÂ

Raman
