Greetings John. I think you want to direct your mail to the Open MPI
User's mailing list -- this list is for the testing framework known as
the MPI Testing Tool (MTT). It's a sub-project of the greater Open
MPI project, but the audience over here isn't well-equipped to answer
specific questions about the Open MPI software package.

Hello OpenMPI folks,
I've got a large pool of Macs running Leopard that are all on an
xgrid. However, I can't seem to use the mpirun that comes with
Leopard with the xgrid. I've got my grid and password environment
variables set up okay on my controller, all the xgrid command line
commands work (displaying grid IDs, things like that) but mpirun
only wants to run things on the local host.
I'm extremely new to OpenMPI and only slightly less new to Macs so
there's probably something very obvious that I'm missing, but I'm
trying what's detailed on this page: http://www.macresearch.org/runing_mpi_job_through_xgrid
(the /bin/hostname example). Here's my output:
as-0003-l:~ locadmin$ mpirun -n 8 /bin/hostname
as-0003-l.lib.mcmaster.ca
as-0003-l.lib.mcmaster.ca
as-0003-l.lib.mcmaster.ca
as-0003-l.lib.mcmaster.ca
as-0003-l.lib.mcmaster.ca
as-0003-l.lib.mcmaster.ca
as-0003-l.lib.mcmaster.ca
as-0003-l.lib.mcmaster.ca
Issuing the same command with -nolocal yields the following:
as-0003-l:~ locadmin$ mpirun --nolocal -n 8 /bin/hostname
--------------------------------------------------------------------------
There are no available nodes allocated to this job. This could be
because
no nodes were found or all the available nodes were already used.
Note that since the -nolocal option was given no processes can be
launched on the local node.

Thanks very much for any help you can provide!
