Re: [HTCondor-users] Ranking on number of cpu cores

[Oliver Coleman <oliver.coleman@xxxxxxxxx>]

That was it, thanks. :) Though looking more closely at the long list of various kinds of lab machines in the condor installation I use (various numbers of cores, cpu types and speeds), it actually looks like kflops is being calculated per machine, not core, after all...

Hi there,

Just wondering how I can rank by the number of cpus (cores) in a submit file?ÂI suppose it's something like:

Rank=num_cpus

+RequiresWholeMachine=True

But whatever I put for "num_cpus"Âeither doesn't seem to work (the jobs seem to idle instead of running) or it selects dual-core machines instead of the available quad-core machines.

I was using "rank=kflops" until I realised that this seems to be calculated per slot/core rather than total machine (which makes sense), however my software is multi-threaded so I use the whole machine.

Cheers,

Oliver
