problems with openmpi
 
Note that OpenFOAM-2.0 uses openmpi-1.5.3, which is a beta version that has known issues with GridEngine. See http://www.open-mpi.org/community/li...1/03/15930.php for more information.

If this affects you and you wish to continue using openmpi-1.4.3 with OpenFOAM-2.0 there are two means of doing this.

One method is to hack the etc/config/settings.sh file to reference the preferred version.
Another method is to use the hook provided in this file and define your own
config/openmpi.sh file with the contents:
Code:

# Modified openmpi settings
export FOAM_MPI=openmpi-1.4.3

(see the etc/config/example/openmpi.sh file).

This file is placed somewhere in the hierarchy searched by foamEtcFile. For example under $HOME/.OpenFOAM/2.0.x/config/openmpi.sh
