I would like add a PBS cluster to my Condor pool. There are at least two solutions mentioned in the documentation - gLite/GAHP and BOSCO. After quick review, it seems to me that gLite is now obsolete.
1. Would
you agree?
2. Is
there any cases in which you would recommend using gLite over BOSCO?
3. Where
would I find the gLite code to be placed in GLITE_LOCATION?
gLite/GAHP and BOSCO are two different ways of using the same underlying piece of software, called either âbatch_gahpâ or âblahpâ (depending on where youâre installing HTCondor from). Itâs still maintained (though no longer as part of gLite) and is included
in the HTCondor release. Itâs one of several ways to incorporate a PBS cluster into your HTCondor environment.
If you want user jobs in HTCondor to be directly submitted into PBS, that usually means that users need to indicate in their submit files which jobs are intended to run in PBS (instead of on HTCondor execute nodes). If you can configure a single machine
to be a submit point for both PBS and HTCondor, then thereâs little or no additional admin setup required. Otherwise, youâll need something like BOSCO or HTCondor-CE to handle the jump from HTCondor submit machine to PBS submit machine.
You should also consider options where PBS execute nodes can become temporary members of the HTCondor pool. That way, users donât need to decide where their jobs will run. One way to do this is to modify the PBS setup to start HTCondor (configured as an
execute node) when the machine is idle and stop HTCondor when it wants to start a PBS job.
Another way to do this is something called GlideIn, where you submit jobs to PBS that are HTCondor daemons (configured as an execute node).
Let me know if you want more information on any of these options.
Thanks and regards,
