[Condor-users] Displaying nodes allocated to MPI jobs

[Hahn Kim <hgk@xxxxxxxxxx>]

Hello,

We have successfully launched the simplempi program described in the 
documentation on our cluster using Condor.  However, if we request 4 
processors, condor_q reports only 1 processor allocated to the job.  I 
have modified the simplempi program so that each MPI rank prints out the 
hostname of the machine it is running on and each rank is running on a 
different processor.

When Condor launches an MPI job onto a set of processors, it is actually 
reserving those processors so that no other Condor job will be started 
on processors?  If so, is there a way to display which processors are 
allocated to the MPI job?  Thank you.

Hahn
