This is the site you want (it's MPICH2, not MPICH1, but it's the same
people):

Good luck!

Brock,
Thanks much for the quick reply and information. I thought I might
have been in the wrong place. :) After a google search for that
list, I came up with several options. Do you happen to have a site
URL or other link for the list your talking about? I want to make
sure I'm on the right list
Thanks very much! :)
Brian.

This if for MPICH's mpirun not OpenMPI's mpi run. You will need to
direct questions to the MPICH team and mailing list.
Also be aware that if that is for MPICH-1.x they nolonger develop
it and should move to MPICH-2.x Or switch to another MPI stack like
OpenMPI etc.

I'm new here so forgive me if I ask any dumb questions. But the
first question I have concerns the mpirun script below.
My question is, what does the SYNCLOC=/bin/sync line for in the
script below do, and what complications could arise (if any), from
disabling this option by commenting out the line like #SYNCLOC=/bin/
sync. In some code we are running, we have found that disabling
this option allows high priority jobs to complete in only a couple
of seconds, whereas before they would take several minutes.
What does SYNCLOC do, and if its disabled, what kind of problems
might that cause?
