Have been struggling with this for some time. If anyone has any thoughts would be appreciated.
I've been running 3.0.1 on Centos 5.11 successfully on a number of nodes here. Today I encountered one issue with a node that has Intel composer xe installed on it and is defaulting to intels MPI. All my other nodes run on OpenMPI with success and I would like to execute of301 on this node using the same config. mpi-selector --list returns: lam-i386 lam-x86_64 openmpi-1.4-gcc-x86_64 mpi-selector --query returns: default: openmpi-1.4-gcc-x86_64 level:system but mpirun -which returns /opt/intel/composer_xe_2013_sp1.1.106/mpirt/bin/intel64/mpirun and throws an error saying /opt/intel/composer_xe_2013_sp1.1.106/mpirt/bin/intel64/mpivars.sh: No such file or directory. Foam is configured OpenFOAM-3.0.1/etc/bashrc configures WM_MPLIB to SYSTEMOPENMPI. I have tried setting it to OPENMPI but with no luck. but after initializing with of301 typing $WM_MPLIB at the terminal returns bash: SYSTEMOPENMPI: command not found. I note in the path statement that the intel path statements appear before the/usr/lib64/openmpi/1.4-gcc/bin directory. I'd rather not uninstall the intel compiler but am unsure how to force the system to see openMPI as the default. Any suggestions appreciated. Britt |

Quick answer: Looks like Intel's path is loaded automatically into the PATH variable automatically.
The trick I usually suggest on the wiki for OpenFOAM on Ubuntu, is to use the following symbolic linking commands: Code:
ln -s /usr/bin/mpicc.openmpi OpenFOAM-3.0.1/bin/mpicc ln -s /usr/bin/mpirun.openmpi OpenFOAM-3.0.1/bin/mpirun Code:
which mpirun which mpicc edit: I deleted you're previous thread that had this same exact question.

Thank you for the quick response. Apologies for asking again!
I followed your suggestion. ln -s /usr/bin/mpirun.openmpi /usr/lib64/openmpi/1.4-gcc/bin/mpirun ln -s /usr/bin/mpicc.openmpi /usr/lib64/openmpi/1.4-gcc/bin/mpicc links established correctly but: which mpirun still returns: /opt/intel/composer_xe_2013_sp1.1.106/mpirt/bin/intel64/mpirun but: which mpicc is correct. /usr/lib64/openmpi/1.4-gcc/bin/mpicc clearly still something happening with the path statements. I'll keep at it but let me know if anything else jumps out at you. Thanks for the assistance. |

Quick answer: I don't know if you've solved this issue or not, but another possible solution is to run the following:
Code:
echo PATH= /usr/lib64/openmpi/1.4-gcc/bin/:$PATH The other possible solutions that I can think of are regarding the environment variables. The following command should give us a few ideas: Code:
export | grep MPI Code:
I_MPI_ROOT MPI_ROOT OPAL_PREFIX To unset them, run for example: Code:
unset I_MPI_ROOT

@WYLDCKAT thanks for the follow up:/
After a bit of trial and error and some support from Intel I got around this by adding the following lines at the end of my .bashrc export PATH=/usr/lib64/openmpi/1.4-gcc/bin:$PATH export LD_LIBRARY_PATH=/usr/lib64/openmpi/1.4-gcc/lib:$LD_LIBRARY_PATH Hope this helps anyone who encounters similar issues. |
