Checking the logs, it looks like that fix was in 1.4.3, too.
Do you know if your application has sends/receiv
ompi_info should tell you the current version of Open MPI your path is
pointing to.
Are you sure your path is pointing to the area that the OpenFOAM package
delivered Open MPI into?

Looking at the change log for 1.5.1 I see:
- Use memmove (instead of memcpy) when necessary (e.g., source
and destination overlap).
It seems as though this might be a likely candidate for a change that might
fix my problems if I am indeed using 1.5.3 following the installation of
OpenFOAM?

Interesting. In the same set of updates, I installed OpenFOAM from their
Ubuntu deb package and it claims to ship with openmpi. I just downloaded
their Third-party source tar and unzipped it to see what version of openmpi
they are using, and it is 1.5.3. However, when I do man openmpi, or
ompi_info
What version did you upgrade to? (we don't control the Ubuntu packaging)
I see a bullet in the soon-to-be-released 1.4.5 release notes:
- Fix obscure cases where MPI_ALLGATHER could crash. Thanks to Andrew
Senin for reporting the problem.
But that would be surprising if this is what fixed yo
As of two days ago, this problem has disappeared and the tests that I had
written and run each night are now passing. Having looked through the
update log of my machine (Ubuntu 11.10) it appears as though I got a new
version of mpi-default-dev (0.6ubuntu1). I would like to understand this

Yes, your output is what I was expecting. Actually, your output is what I
get if I compile the code I attached in my first email. However, our
application is actually doing some 'smart' stuff when you dynamically
allocate memory by putting headers around the memory block -- I am guessing
that this
I guess your output is from different ranks. YOu can add rank infor
inside print to tell like follows:
(void) printf("rank %d: gathered[%d].node = %d\n", rank, i,
gathered[i].node);

1.4.3. after I add rank, the output is
