First of all, pardon me if this is a stupid comment; I am learning the
nuts-and-bolts of parallel programming; but my comment is as follows:
Why can't this be done *outside* openMPI, by calling Linux's processor
affinity APIs directly? I work with a blade server kind of
There is not, right now. However, this is mainly because back when I
implemented the processor affinity stuff in OMPI (well over a year
ago), no one had any opinions on exactly what interface to expose to
the use. :-)
So right now there's only this lame control:

It looks like you ran into a bug in Libtool. Unfortunately, in order
to better support Fortran 90 when building shared libraries, we use a
beta version of Libtool 2, which means we're living a bit more on the
edge than we'd like. I have a patch for this issue that I'll be

We already have --pernode, which spawns one process per node. You can also
launch one process/slot across all available slots by simply not specifying
the number of processes.
I gather this option would say "spawn N procs/node across all nodes" - I can
understand the possible usefulness, but I'm n
I recently saw this on the mpiexec mailing list and pondered that this
would be a useful feature for Open MPI as well. :-)
I can't seem to enter a trac ticket and seem to be having issues w/ my
browser at the moment, but wanted to get this out there.

I have recently completed a number of performance tests on a Beowulf
cluster, using up to 48 dual-core P4D nodes, connected by an Extreme
Networks Gigabit edge switch. The tests consist of single and multi-node
application benchmarks, including DLPOLY, GROMACS, and VASP, as well as
specific tests o
