Hi,
I am using 2 software, one is called Open Foam and the other called EMPIRE that
need to run together at the same time.Open Foam uses Open MPI implementation
and EMPIRE uses either MPICH or intel mpi.The version of Open MPI that comes
with Open Foam is 1.6.5.I am using Intel (R) MPI Library for linux * OS,
version 5.1.3 and MPICH 3.0.4.
My problem is when I have the environment variables of either mpich or Intel
MPI sourced to bashrc, I fail to run a case of Open Foam with parallel
processing ( You find attached a picture of the error I got ) This is an
example of a command line I use to run Open Foammpirun -np 4 interFoam -parallel
Once I keep the environment variable of OpenFoam only, the parallel processing
works without any problem, so I won't be able to run EMPIRE.
I am sourcing the environment variables in this way:
For Open Foam:source /opt/openfoam30/etc/bashrc
For MPICH 3.0.4
export PATH=/home/islem/Desktop/mpich/bin:$PATHexport
LD_LIBRARY_PATH="/home/islem/Desktop/mpich/lib/:$LD_LIBRARY_PATH"export
MPICH_F90=gfortranexport MPICH_CC=/opt/intel/bin/iccexport
MPICH_CXX=/opt/intel/bin/icpcexport
MPICH-LINK_CXX="-L/home/islem/Desktop/mpich/lib/ -Wl,-rpath
-Wl,/home/islem/Desktop/mpich/lib -lmpichcxx -lmpich -lopa -lmpl -lrt -lpthread"
For intel
export
PATH=$PATH:/opt/intel/bin/LD_LIBRARY_PATH="/opt/intel/lib/intel64:$LD_LIBRARY_PATH"export
LD_LIBRARY_PATHsource
/opt/intel/compilers_and_libraries_2016.3.210/linux/mpi/intel64/bin/mpivars.sh
intel64
If Only Open Foam is sourced, mpirun --version gives OPEN MPI (1.6.5)If Open
Foam and MPICH are sourced, mpirun --version gives mpich 3.0.1If Open Foam and
intel MPI are sourced, mpirun --version gives intel (R) MPI libarary for linux,
version 5.1.3
My question is why I can't have two MPI implementation installed and sourced
together. How can I solve the problem ?
