This seems to be the problem -- it's pointing to the "wrong" libmpi (and friends). Ensure that you're using /usr/local/bin/mpicc to compile your apps. Then you might also want to prefix the LD_LIBRARY_PATH environment variable with /usr/local/lib to ensure that you pick up your local Open MPI installation libraries (instead of the ones in /usr/lib). For example: export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH /usr/local/bin/mpicc hello_c.c -o hello_c -g /usr/local/bin/mpirun -np 4 hello_c Try that. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
