[HTCondor-users] question on scheduler max jobs running

[Hyun Woo Kim <hyunwoo@xxxxxxxx>]

Hello HTC developers,

I am one of Fermilab glideinwms(GWMS) developer team.

One behavior of GWMS is, it stops using a scheduler when the sum of 

TotalRunningJobs and TotalSchedulerJobsRunning from that scheduler

is near MaxJobsRunning from the same scheduler.

(We are aware that the definition of MaxJobsRunning has changed since HTC 8.3.2)

We are trying to modify this behavior of GWMS such that GWMS can make this decision

based only on TotalRunningJobs, 

i.e. we want to ignore TotalSchedulerJobsRunning when GWMS makes this kind of decision

because scheduler universe jobs  (e.g. dagman jobs) are not handled by GWMS.

In the current 8.2.X release where MaxJobsRunning includes all universe jobs(except grid univ.),

do you provide any other scheduler parameter or scheduler classad that applies only to Vanilla universe jobs?

One very crude idea that occurred to me was defining a new limit inside GWMS code like

MaxJobsRunning-Vanilla- * X

where X can be a portion of vanilla running jobs in the total running jobs.

Thanks,
