Re: [HTCondor-users] Limiting total resource share granted to single users

It does not matter where you run the command,  it is a command to the central manager (the condor_negotiator actually).  so the limit applies to the entire pool.

Thanks! Just to clarify - that needs to be run on the submit node/wherever schedd is running, right?

you can use

condor_userprio -setceiling

Hi,

I would like to ask if there is a way to limit the total amount of
resources granted to a single user, e.g. set up a limit that a single
user can only obtain, say, 85% of all the available CPUs. I know that
there are priorities for resource negotiation etc, but I am looking more
towards prevention of resource hogging by a single user, which can be a
real problem on smaller compute clusters.

Thanks in advance for help!

Best,

-Jacek
