Re: [Condor-users] parallel jobs on a single machine with double core

Hi Diana,

You can use the ParallelSchedulingGroup tag to stop your job from fragmenting onto different machines, e.g. the following in an execute machine's condor_config.local file should achiueve this:

ParallelSchedulingGroup     = "$(HOSTNAME)"
DedicatedScheduler          = "DedicatedScheduler@xxxxxxxxxxxxxxxxxxxxxxxxxx"
STARTD_EXPRS = $(STARTD_EXPRS), DedicatedScheduler, ParallelSchedulingGroup RANK = Scheduler =?= $(DedicatedScheduler)

Fuller documentation and an example using MPICH2 for our Condor environment can be found at http://www.escience.cam.ac.uk/projects/camgrid/mpi.html.

I would like to know if it is possible - when running a parallel job,
using condor parallel universe - to define that you want the job to run
on a single machine (with multiple processors). To be more specific, I
have a cluster with several multiprocessors and I want my job to be
split by the processors of a single machine.

Thanks in advance
