The error message looks like it's no where near an MPI function; I would
guess that this is not an Open MPI problem but, particularly given your
statements about Snow Leopard) a CMAQ problem. The easiest way to debug
on OS X is to launch the application code in a debugger, something like:
mpiru
Also, please be aware that we haven't done any testing of OMPI on Lion, so this
is truly new ground.

Matt,
Are you sure you are building against your macports version of openmpi and not
the one that ships w/ lion. In the trace back are items 4-9, that end w/
x86_64pg from the pgi compiler. You said you are using pgf90 and pgcc but in
the configure input it looks like gcc is being used on lion.
Hi,
I'm trying to run CMAQ - an air quality model developed by the US EPA - on a
Mac (Lion) using OpenMPI (1.5.3) installed with MacPorts.
I am able to run CMAQ in parallel, and am able to run small programs that
use OpenMPI.
I set the OpenMPI environment variables to use pgf90/pgcc (10.9) as my
Hi Ralph,
Yes, you are right. Those nodes were still pointing to an old version.
I'll check the installation on all nodes and try to run it again.
Thanks,

That error makes no sense - line 335 is just a variable declaration. Sure you
are not picking up a different version on that node?

Hi,
Currently I'm having trouble to scale an MPI job beyond a certain limit.
So I'm running an MPI hello example to test beyond 1024 but it failed with
the following error with 2048 processes.
It worked fine with 1024 processes. I have enough file descriptor limit
(65536) defined for each process
No, Open MPI doesn't use the names in the hostfile to figure out which TCP/IP
addresses to use (for example). Each process ends up publishing a list of IP
addresses at which it can be connected, and OMPI does routability computations
to figure out which is the "best" address to contact a given
I don't know if this is it, but if you use the name localhost, won't
processes on both machines try to talk to 127.0.0.1? I believe you need
to use the real hostname in you host file. I think that your two tests
work because there is no interprocess communication, just stdout.

Hi Clinton,
Just wondering if anyone can point me to the detailed information on
how to setup multiple nodes and network them together to use OpenMPI.
Also what is the proper way to specify which nodes to run on. I wish
to use OpenMPI on the Windows XP or Windows Server 2008 platform, with
