abaqus

[Joshua Bernstein]

Kevin,

	In my experience, Abaqus doesn't require the use of mpiexec and 
correctly handles TORQUE jobs correctly. In fact Abaqus as explicity 
support for submitting jobs directly to TORQUE. You can don something 
like this in your Abaqus site files:

queue_name["abaqus_8cpus"]
queue_cmd="qsub -q abaqus -S /bin/bash -V -l nodes=1:ppn=8 %S"

You'll then need to create a TORQUE queue called "abaqus" (the argument 
to -q above).

Then a user can submit a job to TORQUE using the abaqus command:

abaqus job=myjob queue=abaqus_8cpus cpus=8

I'm currently working on seeing if its REALLY required to use mpiexec 
with Abaqus, but again, I haven't seen a use for it. Modern Abaqus 
versions, say like 6.6-3 use HP-MPI, which used mpd, and does a 
wonderful job managing processes and cleaning up after itself.
