Re: [OMPI users] Not pointing to correct libraries

I am not sure Fedora comes with Open MPI installed on it by default (at least my FC13 did not). You may want to look at trying to install the Open MPI from yum or some other package mananger. Or you can download the source tarball from http://www.open-mpi.org/software/ompi/v1.4/, build and

Hello, Rob, and Open MPI users, Thank you for your advice. I understand that current Open MPI 1.5.3 Win-32bit binary distributed from this site don't support MPI-IO on NTFS. I try to check this problem with using other code. The code is the following code:

Re: [OMPI users] WRF run on multiple Nodes

Did you request an allocation from PCM? If not, then PCM will block you from arbitrarily launching jobs on non-allocated nodes. Print out your environment and look for any envars from PCM and/or LSF (e.g., LSB_JOBID). I don't know what you mean about "no OMPI application is yet integrated with
