Perhaps a telecon (myself, Jeff S, and you) would be best at this
stage. I confess I'm now confused too - what you describe is precisely
what we already do.
Let me know when you are available and we'll try to work out a time -
might as well do that off list so we don't bang everyone's inbox.

Ummm....I'll let you guys work this out on PLPA. However, just to
clarify, OMPI currently binds to cores, not logical cpus. It is the
PLPA that is "dumb" and provides the plumbing to do what OMPI tells
it.

Ahh, if that's the case then this isn't something that PLPA
needs to be involved in then! I'm getting confused here,
haven't had a coffee since Monday, must be the reason. :-)
What we really want is for the usual execution of:
mpiexec /path/to/my/code $arguments
to launch via the PBS TM API, work out what cores are
available to it on the nodes assigned to it and then
bind appropriately to them. Easy, see.. ;-)
cheers!
