[Condor-devel] Per machine resource limits in 7.6/7.8

[Alan De Smet <adesmet@xxxxxxxxxxx>]

I had an interesting chat with a Condor Week attendee who has
some challenges that I'm not sure how to handle.  They have
various limited resources (software licenses) , but the limits
aren't global, they're per machine, so the concurrency limits
aren't a good fit.  Furthermore a job might claim multiple
identical resources at once, in much the same way a single job
might claim multiple cores.

Custom resource limits per eje's proposal
(https://condor-wiki.cs.wisc.edu/index.cgi/tktview?tn=2905) seem
like a good fit, and he was open to the idea.  However, that's
7.9 territory, and they'd prefer to not use a development
release.

Is there a good solution for 7.6 or 7.8?  All I've got in having
slots START expressions total up usage by other slots and testing
against the limit, which seems clumsy.
