Hi I installed openmpi 1.2.2 on a quad core intel machine running fedora 6 (hostname plankton) I set PATH and LD_LIBRARY in the .zshrc file: $ echo $PATH /opt/openmpi/bin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/jody/bin $ echo $LD_LIBRARY_PATH /opt/openmpi/lib:
When i run $ mpirun -np 2 ./MPITest2 i get the message ./MPI2Test2: error while loading shared libraries: libmpi_cxx.so.0: cannot open shared object file: No such file or directory ./MPI2Test2: error while loading shared libraries: libmpi_cxx.so.0: cannot open shared object file: No such file or directory However $ mpirun -np 2 --prefix /opt/openmpi ./MPI2Test2 works. Any explanation? Second problem: I have also installed openmpi 1.2.2 on an AMD machine running gentoo linux (hostname nano_02). Here as well PATH and LD_LIBRARY_PATH are set correctly, and $ mpirun -np 2 ./MPITest2 works locally on nano_02. If, however, from plankton i call $ mpirun -np 2 --prefix /opt/openmpi --host nano_02 ./MPI2Test2 the call hangs with no output whatsoever. Any pointers on how to solve this problem? Thank You Jody
