You're still intermingling your Open MPI and MPICH installations. You need to ensure to use the wrapper compilers and mpirun/mpiexec from the same MPI implementation.
For example, if you use mpicc/mpifort from Open MPI to build your program, then you must use Open MPI's mpirun/mpiexec. If you absolutely need to have both MPI implementations in your PATH / LD_LIBRARY_PATH, you might want to use absolute path names to for mpicc/mpifort/mpirun/mpiexec. > On May 26, 2016, at 3:46 PM, Megdich Islem <megdich_is...@yahoo.fr> wrote: > > Thank you all for your suggestions !! > > I found an answer to a similar case in Open MPI FAQ (Question 15) > FAQ: Running MPI jobs > > > > > > > > > FAQ: Running MPI jobs > Table of contents: What pre-requisites are necessary for running an Open MPI > job?
