How does a user watch the Karma ?

[bzizou]

With OAR2, users could see the karma associated to the scheduling of a job with oarstat, for example:

26199695  R jovanovn    0:20:40 R=2,W=1:0:0,J=B,P=epimed,T=heterogeneous|verysmall (Karma=-0.016,quota_ok)
26199698  R collaog     0:18:08 R=1,W=24:0:0,J=B,N=AN40LGMcBn5078,P=elmerice,T=heterogeneous|veryverysmall (Karma=0.005,quota_ok)

The Karma is a part of the string contained into the message field of the jobs table. With OAR3, it seems that the message does not contains any Karma information, and anyway, the message is not printed by oarstat.

How does the user know about the Karma with OAR3?

If fairshare scheduling is enable, Karma value is normally added in job_message function:

oar3/oar/lib/job_handling.py

Line 630 in c6c84f5

message += " " + "(Karma={})".format(job.karma)

So fixing the printing issue of oarstat should be sufficient.

Well, this leads to another question: actualy, fairsharing was not enabled into my configuration, because the JOB_PRIORITY configuration variable is missing from the default oar.conf file I think...

[augu5te]

Sure fairsharing is disabled by default ( JOB_PRIORITY="FIFO") and oar.conf needs some care and polish

Actually, oarstat, in the default mode, prints the message, but the Karma appears in the message at some times, but not once the job is running...

A few seconds later:
