Greetings,
I was hoping someone could help me with the following situation. I have a
program which has no MPI support that I'd like to run "in parallel" by
running a portion of my total task on N CPUs of a PBS/Maui/Open-MPI
cluster. (The algorithm is such that there is no real need for MPI, I

I tried this on a humble PC and it works there.
I see in the --mca mpi_show_mca_params 1 print out that there is a

There should be an mpi_paffinity_alone parameter;
Hi John
I'm afraid that the straightforward approach you're trying isn't going to
work with Open MPI in its current implementation. I had plans for supporting
this kind of operation, butnot happening. And as you discovered, you
cannot run mpiexec/mpirun in the background, and the

Because of different kernel version, or old versions, not all files
I think you actually have a few options:
1. If I'm reading the original mail right, I don't think you need
mpirun/mpiexec at all. When you submit a scripted job to PBS, the
script runs on the "mother superior" node -- the first node that was
allocated to you. In this, case it's your only
Hello,
I finally managed to run open MPI with uDAPl but all MPI programs hang
up, when they use MPI_Recv. If I use TCP or native InfiniBand instead,
it works. Maybe you have an idea where the problem could be.
Thanks

Andreas,
I am going to guess at a minimum the interfaces are up and you can ping
them. On Solaris there is an additional step required and that is
initializing the dat registry. If "/usr/sbin/datadm -v" does not show
some driver output then you would need to run "/usr/sbin/datadm -a
No problem! Glad we could help, and many thanks for tracking down
some of our bugs.

Well, I'm sorry to have caused even a smidgen of grief here.
I moved aside the *paffinity_linux* module and la and it still
