Hi,
I'm using the LAM/MPI 7.1.2. I have the lam daemons running.
My main (master) process seems to be failing at MPI_Init. Here is my
command and output.
I've added some debug fprintf in the source code. It's failing at
kinit() but my debug printf are
not coming out of that function. I don't know why. Any idea why kinit
is failing??????

It seems that [at least] one of the 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.
