I am presently trying to get OpenMPI up and running on a small cluster
of MacPros (dual dual-core Xeons) using TCP. Opne MPI was compiled using
the intel Fortran Compiler (9.1) and gcc. When I try to launch a job on
a remote node, orted starts on the remote node but then times out. I am
guessing that the problem is SSH related. Any thoughts?
Thanks,
Dave
Details:
I am using SSH, set up as outlined in the FAQ, using ssh-agent to allow
passwordless logins. The paths for all the libraries appear to be OK.
A simple MPI code (Hello_World_Fortran) launched on node01 will run OK
for up to four processors (all on node01). The output is shown here.
node01 1247% mpirun --debug-daemons -hostfile machinefile -np 4

Rank 0 is present in Fortran version of Hello World.

For five processors mpirun tries to start an additional process on
node03. Everything launches the same on node01 (four instances of
Hello_World_Fortran are launched). On node03, orted starts, but times
out after 10 seconds and the output below is generated.
