Description of problem: The executables such as mpicc mpirun and all the other mpi* are not in the PATH and need to be called with the full path e.g : /usr/lib64/openmpi/bin/mpirun Version-Release number of selected component (if applicable): Name : openmpi-devel Arch : x86_64 Version : 1.5.4 Release : 5.fc17.1 How reproducible: Always Steps to Reproduce: 1. Install openmp-devel 2. Try to compile a mpi program by running mpicc 3. Actual results: $ mpicc prog.c bash: mpicc: command not found... Expected results: compilation of prog.c Additional info: Binary are at the wrong place ?
Did you use the module command to set up your path and environment for the mpi system you are using? Since Fedora has multiple mpi packages available, and different users on the same machine may want to use different mpis at the same time, we can't simply install their binaries in the standard path, because then there'd be no way to tell which mpicc (etc) a user wanted.
I did not know there were multiple mpi packages... I thought that openMPI was alone to provide the MPI implementation under Linux. Sorry... I close the bug.
