Thank You Jeff Squyres.
I have checked out the web page
http://www.open-mpi.org/community/lists/announce/2009/03/0029.php, then the
page https://svn.open-mpi.org/trac/ompi/ticket/1853 , but the web page
svn.open-mpi.org seems crash.
Then I tried OpenMpi V1.3.2 for many different configuratio
Remember also that the RTE API's changed between 1.2 and 1.3 - so I'm not
sure what will happen in that case. It could be that the ones touching the
MPI layer remained stable (don't honestly recall), though I believe there
are RTE calls in 1.3 that don't exist in 1.2. I would think you would have a
I still have not been able to reproduce the hang, but I'm still
looking into it.
I did commit a fix for the datatype copy error that I mentioned
(r21080 in the Open MPI trunk, and it is in the pipeline for v1.3).
Can you put in a print statement before MPI_Finalize, then try the
program a
I'd actually be surprised if it works.
The back-end sizes of Open MPI structures definitely changed between
1.2 and 1.3. We used to think that this didn't matter, but then we
found out that we were wrong. :-) Hence, I'd think that the same
exact issues you have with taking a 1.2-compiled
I think Serge is talking about compiling the application against one
version of Open MPI, linking dynamically, then running against another
version of Open MPI. Since it's dynamically linked, the ORTE/OMPI
interactions are covered (the version of mpirun, libopen-rte, and libmpi
all match). Th
It's hard for me to believe that would work as there are fundamental
differences in the MPI-to-RTE interactions between those releases. If it
does, it could be a fluke - I personally would not trust it.

As far as I can tell from reading the release notes for v1.3.2, the
binary compatibility has not been announced yet. It was rather a bug fix
Thanks for the patch. I applied a version of it to the Open MPI trunk
(r21079) and started the process of moving it to the v1.3 release
series:

Thanks for the bug report.
I am having a difficult time reproducing the error. Are you running on
a single machine using shared memory or across multiple machine using
a high speed network?
Based on your bug report, my suspicion is that an event is not being

Sorry for the long delay to respond.
It is a bit odd that the hang does not occur when running on only one
host. I suspect that is more due to timing than anything else.
I am not able to reproduce the hang at the moment, but I do get an
occasional datatype copy error which could be symptoma
