[Condor-users] condor & MPI

[Rok Roskar <roskar@xxxxxxxxxxxxxxxxxxxx>]

I'm trying to test a set up of dedicated resources in our condor pool. 
I don't want the MPI jobs to follow any different scheduling 
rules/priorities/policies than other jobs, so all I added to the local 
config files for the two machines I want to test initially is:

DedicatedScheduler = ``DedicatedScheduler@xxxxxxxxxxxxxxxxxxxxxxxxxxx''
STARTD_EXPRS = $(STARTD_EXPRS), DedicatedScheduler

(the quotes around DedicatedScheduler host name look suspect - are they 
supposed to be like that? I got these lines straight from the manual)

I've restarted condor on the two machines after having changed the 
settings.

However, my jobs(submitted from the DedicatedScheduler machine) aren't 
starting. So a few diagnostics I've tried to perform:

- When I run condor_status -l for the two machines, nothing about the 
DedicatedScheduler appears in the resource ads (is it supposed to?).

- When I run condor_useprio -allusers, the DedicatedScheduler "user" 
appears. I'm not sure this is supposed to happen, I didn't see anything 
about this in the docs

- checking the job ad (running condor_q -l), everything appears in 
order, the correct dedicated scheduler is listed etc.

Thanks for your help!
