Kamal,
that *could* work (and i am not sure anybody did much testing about that)
as of now, it is required OpenMPI is installed at the same location on
all the nodes.
i suspect it is installed in /.../ompi-x86 on machine A and
/.../ompi-x86_64 on machine B
if i am wrong, a simple workaround (so you can find orted) is to invoke
mpirun with the full path (e.g. /.../ompi/bin/mpirun) instead of just mpirun
you might also need to configure ompi with --enable-heterogeneous
Cheers,
Gilles

Hello,
Iam trying to couple two programs running on two different machines
using openMPI. Machine A is a 32-bit machine and machine B is a 64-bit
machine. So, the configuration is like:
*IA32 Machine A with 32-bit binary **+****x64 Machine B with 64-bit
binary.*
**
*Does openMPI allow such a communication?*I was able to create 32-bit
and 64-bit binaries on both machines using openMPI. I can also run the
executables on both machines separately. But, if I want to communicate
between two machines, it simply does not work. I receive the below
messages:
/bash: orted: command not found/
/--------------------------------------------------------------------------/
/ORTE was unable to reliably start one or more daemons./
/This usually is caused by:/

Thanks a lot in advance.

Kamal
