[OMPI users] "almost there" in getting MPI to run
Hi all, After trying cygwin and the windows build of Open MPI, I've now focused on using linux for my mpif90 code testing/development on my laptop. I've managed to install Open MPI, and it works, sort of. Strangely(?), in both my laptop and the cluster, the number of threads from the command call MPI_Comm_size ( MPI_COMM_WORLD, p, error ) Results on only one active thread, when my laptop is a quad-core (should be 8 threads). The same happens running in the cluster, where each "blade" has 8 cores. What am I missing here? Is there more configuration to be done? Actually, can I manually set the number of working threads? Thanks for any help. I hope I'm "almost there". Joao

[OMPI users] Open MPI 1.5.4 on windows g95 / mpif90 support
