I installed OpenMPI (I have a simple dual core AMD notebook with Fedora 16) via:

# yum install openmpi
# yum install openmpi-devel
# mpirun --version
mpirun (Open MPI) 1.5.4

I added:

$ PATH=PATH=/usr/lib/openmpi/bin/:$PATH

Is this a typo - double PATH?


$ LD_LIBRARY_PATH=/usr/lib/openmpi/lib/

It needs to be exported, so that child processes can use it too.

The file (actually, a link) it claims it can't find: libmpi_f90.so.1, is clearly there. And LD_LIBRARY_PATH=/usr/lib/openmpi/lib/.

What's the problem?
