I'm experimenting with heterogeneous applications (x86_64 <-->
ppc64), where the systems share the file system where Open MPI is
What I would like to be able to do is something like this:
mpirun --np 1 --host host-x86_64 --prefix /opt/ompi/x86_64
a.out.x86_64 : --np 1 --host host-ppc64 --prefix /opt/ompi/ppc64
Unfortunately it looks as if the second --prefix is always ignored.
My guess is that orte_app_context_t::prefix_dir is getting set, but
only the 0th app context is never consulted (except in the dynamic
process stuff where I do see a loop over the app context array).
I can of course work around it with startup scripts, but a command
line solution would be attractive.
This is with openmpi-1.2.
