Hmm, I didn't know that. Is OS X's small stack something that can be alleviated with "ulimit" in bash? Right now, I have my ulimit set to unlimited. Does this still work with OpenMPI? (I might be wrong, but doesn't MPI work over TCP, such that new spawned processes on my host wouldn't be affect

I figured. I've been using Ubuntu so long that I never expect any issues with upgrades (until Unity came out..) From what I've read however, ar on Lion seems to be a bit buggy (that seems to be the consistent complaint on the MacPort support forums), but overall I have faith that it can work. On

Ack, that's a very good point. I made sure to compile all my other dependencies (NetCDF, IOAPI) with PGI, but I overlooked that one. I'll admit that even after years of working with these models, I'm still never sure when I can and can't mix binaries compiled with different compilers. I used cer

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. On Aug 9, 2011, at 3:00 PM, Doug Reeder wrote: > 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 it

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.

[OMPI users] CMAQ crashes with OpenMPI

2011-08-09 Thread Matthew Russell
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
