What happens is mpirun does under the hood <remote_exec> orted And your remote_exec does not propagate LD_LIBRARY_PATH one option is to configure your remote_exec to do so, but I'd rather suggest you re-configure ompi with --enable-orterun-prefix-by-default If your remote_exec is ssh (if you are not running under a supported batch manager), then ssh node188 ldd $path_to_openmpi_bin/orted should show zero unresolved libraries
