Hi,
When trying to execute an application that spawns to another node, I
obtain the following message:
# ./mpirun --hostfile /root/hostfile -np 2 greetings
Syntax error: "(" unexpected (expecting ")")

Hi,
I have a question regarding merging intracommunicators.
Using MPI_Spawn, I create on designated machines child processes,
retrieving an intercommunicator each time.
With MPI_Intercomm_Merge it is possible to get an intracommunicator
containing the master process(es) and the newly spawned child

Yes, a memory bug has been my primary focus due to the not entirely
consistent nature of this problem; I valgrind'ed the app a number of
times, to no avail though. Will post again if anything new comes up...
Thanks!

Yes, that's the normal progression. For some reason, OMPI appears to
have decided that it had not yet received the message. Perhaps a
memory bug in your application...? Have you run it through valgrind,
or some other memory-checking debugger, perchance?

Ah, I see the real problem: your C and Fortran compilers are not
generating compatible code. Here's the relevant snipit from config.log:
configure:33849: checking size of Fortran 90 LOGICAL
configure:33918: gcc -DNDEBUG -O2 -g -pipe -m32 -march=i386 -
mtune=pentium4 -fno-strict-aliasing -I. -
Attached is the requested info. There's not much here, though...it
dies pretty early in.

Unfortunately, so far I haven't even been able to reproduce it on a
different cluster. Since I had no success getting to the bottom of this
problem, I've been concentrating my efforts on changing the app so that
there's no need to send very large messages; I might be able to find
time later to
Hello,
I'm having troubles to run my software after our administrators changed

These programs are mainly for internal testing of Open MPI, and are
actually being phased out. We don't actively test them anymore, so I
can't vouch for how well they'll work or not.
A top-level "make test" used to make them.

Hi all, Could someone suggest me, how to compile programs
given in test directory of the source code? There are couple of directories
within test which contains sample programs about the usage of datastructures
being used by open-MPI. I am able to compile some of the directories at it was
