I'm using Open MPI 1.6.5 to run OpenFOAM in parallel on several VMs on a cloud.
mpirun hangs without any error messages. I think this is a firewall issue.
Because when I open all the TCP ports(1-65535) in the security group of VMs,
mpirun works well. However I was suggested to open as less ports
which network are your VMs using for communications ?
if this is tcp, then you also have to specify a restricted set of allowed
ports for the tcp btl
that would be something like
mpirun --mca btl_tcp_dynamic_ports 49990-50010 ...
please double check the Open MPI 1.6.5 parameter and syntax with
om
Hi!
Thank you Jeff for you suggestion. But, I am still not able to understand what
do you mean by using absolute path names to for mpicc/mpifort-mpirun/mpiexec ?
This is how my .bashrc looks like
source /opt/openfoam30/etc/bashrc
export PATH=/home/Desktop/mpich/bin:$PATHexport
LD_LIBRARY_PATH="/h
In addition, you might want to consider upgrading to Open MPI v1.10.x (v1.6.x
is fairly ancient).

The example you list below has all MPICH paths -- I don't see any Open MPI
setups in there.
What I was suggesting was that if you absolutely need to have both Open MPI and
MPICH installed and in your PATH / LD_LIBRARY_PATH / MANPATH, then you can use
the full, absolute path name to each of the
Hi!
Thank you Jeff. I was able to run a case of OF by setting the absolute path
name for mpiexec. But, when I wanted to run a coupled case in which OF is
coupled with dummyCSM through EMPIRE using these three command lines:
mpiexec -np 1 Emperor emperorInput.xml
mpiexec -np 1 dummyCSM dummyCSM
I'm afraid I don't know much about OpenFoam. You'll likely need to ask
assistance from the OpenFoam community.
