I installed intel PSM2 and then configured open mpi as follow.
./configure \
--prefix=$HOME/ompi_install \
--with-psm2=$HOME/PSM2_install/usr \
--with-psm2-libdir=$HOME/PSM2_install/usr/lib64
however, when I ran a Hello prgram, it said ....
mpirun -n 2 hi0
mca_base_component_repository_open: unable to open mca_mtl_psm2: libpsm2.so.2:
cannot open shared object file: No such file or directory (ignored)
mca_base_component_repository_open: unable to open mca_mtl_psm2: libpsm2.so.2:
cannot open shared object file: No such file or directory (ignored)
--- Hi from rank = 0
--- Hi from rank = 1
I had to manually add the following path to let the error message disappeared:
export
LD_LIBRARY_PATH=${MPIDIR}/lib:$HOME/PSM2_install/usr/lib64:$LD_LIBRARY_PATH
is it the right way to use PSM2 in openmpi?
