Great point from David !
As a side note, you can
configure --enable-mpirun-prefix-by-default ... && make install
If you choose to do so, you will not have to set LD_LIBRARY_PATH since
it will be "built in" the Open MPI binaries/libraries (via the -rpath
linker option)

On Sat, Ja
I used to be able to (e.g. in Open MPI 3.1) put the line
rmaps_base_oversubscribe = true
in my `openmpi-mca-params.conf`, and this would enable oversubscription by
default. In 4.0.0, it appears that this option doesn't work anymore, and I
have to use `--oversubscribe`.
Am I missing something, o
The error about not finding shared libraries can be fixed by adding the proper
path to LD_LIBRARY_PATH, which Ralph has already mentioned. If Open MPI is
installed in $HOME/openmpi, LD_LIBRARY_PATH needs to be set like this:
export LD_LIBRARY_PATH=$HOME/openmpi/lib:$LD_LIBRARY_PATH
The mpi libr
Serdar,
you need to export PATH and LD_LIBRARY_PATH in your .bashrc
(e.g. export PATH=$HOME/openmpi/bin:$PATH)
Also, make sure you built your application with Open MPI installed in $
HOME/openmpi
Cheers,

Hi folks,
After installing OpenMPI, I executed these lines
