I'm running a 4 processor sun machine with solaris 9. It actually has
the SUN hpc library (mpi stuff) installed. I'm using a high end package
that uses lam, and I get the following message from lam. lamboot works
fine, mpcc works fine (it's a simple program that just prints out hello
world from each processor), but then there seems to be a conflict with
sun's mprun. I decided to run the test suite to duplicate the errors
there (they compile fine but all throw the same error):
It seems that [at least] one of processes that was started with mpirun
did not invoke MPI_INIT before quitting (it is possible that more than
one process did not invoke MPI_INIT -- mpirun was only notified of the
first one, which was on node n0).
mpirun can *only* be used with MPI programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
to run non-MPI programs over the lambooted nodes.
