a) As Rayson mentioned: the libraries are available on the slaves? b) It might be necassary to export an LD_LIBRARY_PATH in you .bashrc or forward the variable by Open MPI to point to the location of the libraries. c) It could also work to create a static version of Open MPI by --enable-static --disable-shared and recompile the application. -- Reuti > > > On Mon, Apr 2, 2012 at 2:52 PM, Rayson Ho <raysonlo...@gmail.com> wrote: > On Sun, Apr 1, 2012 at 11:27 PM, Rohan Deshpande <rohan...@gmail.com> wrote: > > error while loading shared libraries: libmpi.so.0: cannot open shared > > object file no such object file: No such file or directory. > > Were you trying to run the MPI program on a remote machine??
