I have problem when running a simple mpi program. I have 2 nodes and lamboot starts successfully:

~ lamboot -v -ssi boot rsh test/hostfile

LAM 7.1.2/MPI 2 C++/ROMIO - Indiana University

n-1<2954> ssi:boot:base:linear: booting n0 (node3)
n-1<2954> ssi:boot:base:linear: booting n1 (node2)
n-1<2954> ssi:boot:base:linear: finished

When I run the program:

~ mpirun C test/hello

Hello! I am 0 of 2

The other node doesn't answer.

I used XMPI to view the result, it said invalid node. What can be the problem?

Thanks.
