I installed Open MPI 1.0.1 on two Mac G5s (one with two cpus and the other
with 4 cpus.). I set up ssh on both machines according to the FAQ. My mpi
jobs work fine if I run the jobs on only one computer. But when I ran a job
across the two Macs from the first Mac mac1, I got:

mac1: mpirun -np 6 --hostfiles /Users/me/my_hosts hello_world
tcsh: orted: Command not found.
[mac1:01019] ERROR: A daemon on node mac2 failed to start as expected.
[mac1:01019] ERROR: There may be more information available from
[mac1:01019] ERROR: the remote shell (see above).
[mac1:01019] ERROR: The daemon exited unexpectedly with status 1.
2 processes killed (possibly by Open MPI)

File my_hosts looks like

mac1 slots=2
mac2 slots=4

The orted is definitely on my path on both machines. Any idea? Help is
greatly appreciated!

David
