Without more information, we would just be guessing as to
what is causing the issue you are seeing. As for that guess,
I would guess you are running an out-of-date version of Open MPI.

Doesn't seem to work. This is the appfile I'm using:
# Application context files specify each sub-application in the

# Server
-np 2 server

-np 1 client 0.1.0:2001
And the output:
mpirun --app ./appfile

The problem was that the compilers do not preprocess an assembly files
with the suffix .s, and in this specific case don't expand the two
macros leaf and end. Changing the su

This scenario is known to be buggy in some versions of Open MPI. It is
now fixed in svn version and will be part of the 1.3 release.
To quick fix your application, you'll need to spawn both applications
with the same mpirun, with MPMD syntax. However this will have the
