Usually with this kind of error, more information is shown regarding the failure. Are there any other failure messages displayed? Please see http://www.open-mpi.org/community/help/. Also be aware that "test" is the name of a Unix executable (e.g., /bin/test). I'm assuming that you're trying to run your own executable named "test" (probably an MPI application). Once you get Open MPI working, you may want to run "mpirun -np 2 ./test" to ensure that you run the test executable that you intend.
