Hi --
You are getting the correct output. LAM does not provide a way of getting
exit status back after an MPI_Finalize(). The exit statuses are of
relevance only if the program terminated before MPI_Finalize(). The "-sa"
option of mpirun would list exit statuses of all processes run with
mpirun, irrespective of whether they failed or completed with success, but
the scope of success/failure is from MPI_Init() to MPI_Finalize() only.
Hope this helps...
