[Condor-users] Condor priority model

[Carsten Aulbert <carsten@xxxxxxxxxxxxxxxx>]

Hi,

I've just got a brief question about the priority system. This afternoon the 
situation on our local cluster the situation looked like this (I shrinked 
the output a bit, the columns are: effective priority, real priority, number 
of jobs currently running, hours used so far)

condor_userprio -all -allusers

Y@cluster      21.68  21.68   2  64348.11
B@cluster      82.24  82.24   0  80052.14
S@cluster   47254.34  47.25  53  63419.34
Me@cluster 186124.47 186.12 304 129802.05

The strange thing which hit me (Me@cluster) here was, that user Y submitted 
a cluster with 500 jobs and only 2 of them were running (although all nodes 
in the cluster should match the job requirements [1]). If I understand the 
priority model correctly, as soon as my jobs finish a job from Y should be 
started until the ratio between Y's jobs and my jobs (plus the other 
scheduled jobs represent the effective priority) - but my jobs kept on being 
 started instead of the jobs from Y queuing up.

Anyone reading this here, who can point me to a possible solution/trick?

Carsten

PS: I don't mind that my jobs are actually running, but I just thought it to 
be unfair ;)
