Hi,
Does anybody face problems running Openmpi on two hosts with
different networks (gateway to reach the other) ?
Let say compil02 ip adress is 172.3.9.10 and r009n001 is 10.160.4.1
There is no problem with MPI_init free executables (for example
hostname)
compil02% /tmp/HALMPI/openmpi-1.2.2/bin/mpirun --prefix /tmp/HALMPI/
openmpi-1.2.2 -np 1 -host compil02 hostname : -np 1 -host r009n001
hostname
r009n001
compil02
But as soon as I try a simple hello world , it 's crashing with the
following error message.
Please note that when I try to run hello between r009n001
(10.160.4.1) and r009n002 (10.160.4.2), it works fine
are the 172.x.y.z nodes behind a NAT (hence the communication back
isn't possible - only the stdout from the rsh/ssh is working in this
case)?

Thanks in advance for your help.

PS: same error with openmpi v1.2.5
compil02% /tmp/HALMPI/openmpi-1.2.2/bin/mpirun --prefix /tmp/HALMPI/
openmpi-1.2.2 -np 1 -host compil02 /tmp/hello : -np 1 -host
r009n001 /tmp/hello

It looks like MPI_INIT failed for some reason; your parallel
process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or
environment
problems. This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):
PML add procs failed
