Re: [HTCondor-users] Accounting Groups

[Tom Downes <downes@xxxxxxx>]

With SUBMIT_REQUIREMENTS, you can use the python bindings to enforce complex relationships like group membership.

I've asked for the same level of power to be added to SUBMIT_ATTRS - it would eliminate LIGO's needs for shell wrappers and all the problems of $PATH, moving binaries that comes along for that ride.

One thing we did for a long time at Fermilab was to have a wrapper around condor_submit that
just appended the AccountingGroup attribute to the classad based on the GID of the user.
We also used the presence or absence of an AccountingGroup in PREEMPTION_REQUIREMENTS, i.e. anyone who did not specify an AccountingGroup could be pre-empted, and also used it in RANK statements if we wanted to give a certain group preference on nodes they bought.

Accounting Groups are the way that HTCondor can assign resources out to schedds/jobs via claims.

They work based on pie-spin and can be specified as either dynamic fractions or whole numbers.

1. The recommendation is that you add the accounting groups in a new file within /etc/condor/config.d/. As both condor_config and condor_config.local can be overridden by rpm/condor upgrade.

2. The accounting group can be specified in the job submit file using accounting_group = ââ. However thereâs no direct concept of group membership for accounting-groups. People usually solve this with SUBMIT_ATTRS on the schedd or by checking membership with a SUBMIT_REQUIREMENT.

3. You could make the START _expression_ for the machine an _expression_ of whether the accounting group.

e.g.

START = (target.AccountingGroup =?= âgroup_target.user.groupâ)

Cheers, Iain
