I believe that the openmpi that comes with leopard doesn't support
xgrid. If you type ompi_info|grep xgrid you get nothing. I'm not sure
what apple was thinking.

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.
