Re: [HTCondor-users] HTCondor 24 and STARTER_HIDE_GPU_DEVICES

[Carles Acosta <cacosta@xxxxxx>]

Dear all,

Nobody else is experiencing issues with the STARTER_HIDE_GPU_DEVICES variable set to True in HTCondor 24.0.X, unlike me. Is that correct? Would it be safe to set STARTER_HIDE_GPU_DEVICES = False? The GPUs machines are the only ones we still have on 23.0.XX version due to this issue.

Thank you again.

Best regards,

Carles

Hi Carles:

You are understanding correctly how STARTER_HIDE_GPU_DEVICES is supposed
to work, but it appears that something is going wrong with it. Can you
send me the StarterLog.slot_xxx from a job with STARTER_HIDE_GPU_DEVICES
is true, and I can try to see what is going on? You can email me the
file directly if you are concerned about ip address, etc. in the StarterLog.
