Hi OpenMPI
I am trying to create a Java GUI to control and run an MPI application. I
can run an MPI process from my command line, but am unable to run via the
Java Process Builder.
I get the following error immediately after the process starts:
[SCI053_VM003:02928] ..\..\openmpi-1.6.4\opal\event

It appears to be this one.

I was using the OMPI trunk version 1.9a1r28764...
I tried building openmpi both with and without GC_DOES_PINNING defined,
because I noticed that the MPI calls are handled differently with that
defined (although I may not have defined it in the correct place
ompi/mpi/java/c/mpiJava.h). With
That's understandable - if you don't disable xml2, then hwloc uses the xml2
library to do the topology encoding. We rely on their internal "quasi-xml"
encoding method, which I believe provides some different data (and definitely
different format). I suspect this is causing the confusion, though

What I find very interesting is that the hwloc configure options
--disable-cairo --disable-libxml2 turn the bug off.
I'll keep walking through the execution in gdb maybe I'll
I suspect it has fallen stale as the Java bindings are being reworked as we
speak. I hope to see them committed back to the trunk shortly.

There shouldn't be an inter-language issue here as all the Java code does is
use a JNI module to access the C bindings. Were you using the Java bindings in
the OMPI trunk? Or were you using a 3rd party library?

Yeah, it's failing when trying to unpack the topology obtained from hwloc. My
guess is that one of the following calls changed in hwloc-1.4.3:
if (0 != hwloc_topology_set_xmlbuffer(t, xmlbuffer, strlen(xmlbuffer)))
{
rc = OPAL_ERROR;
free(xmlbuffer);

I don't know if Fedora RPMs include -g in their builds, or if Fedora includes a
debuginfo RPM that you could install such that you can attach a debugger and be
able to dig into OMPI's internals yourself.
If that doesn't work, you might need to build from source yourself, link

The fedora package comes with a debuginfo package that has everything
gdb needs to let me step through the openmpi functions.

I see - I didn't look at the redhat bug list. Sadly, I have no idea how to
debug it. The Fedora package is built optimized, so no OMPI debugging output is
available and a debugger won't tell us a lot.
Best guess is that there is something in the build that doesn't match the
user's system. The n
