Default open-MPI installation

Dear Members,

To run a parallelized version of a program, installed open-MPI via Add/Remove Software option on F12. Installation is complete.
Was just wondering are there any other steps required for installing/setting up MPI?


Regards,
Nermin

Fedora 12 has been obsolete for some time, please upgrade to a
supported version.

As to your question, current versions of Fedora support simultaneous
installation of multiple MPI libraries. This is why the libraries are
hidden by default. To use OpenMPI, you need to load the environment
module first, e.g. on x86_64 run
$ module load openmpi-x86_64
after which e.g. the mpirun and mpicc commands work as expected.
