Jeff,
In short:
Which of the 3 options is the one known to be unstable in the following:
--enable-mpi-threads Enable threads for MPI applications (default:
disabled)
--enable-progress-threads
Enable threads asynchronous communication progress
(default: disabled)
--with-threads Set thread type (solaris / posix)
?
In long (rationale):
Just to make sure we don't contradict each other, you're suggesting
the use of 'listen_thread' but, at the same time I'm telling Prasanna to
_disable_ threads the threads USE flag which translates into the
following logic (in the package):
if use threads; then
myconf="${myconf}
--enable-mpi-threads
--with-progress-threads
--with-threads=posix"
fi
The decision was made based on the configure --help information (most
probably from the 1.1 series), which lead to arbitrarily
enabling/disabling all that has to do with threads using a single
keyword. Now, based on :
https://svn.open-mpi.org/trac/ompi/wiki/ThreadSafetySupport
So, is it only --enable-mpi-threads that is unstable in the "*thread*"
options?
Thanks,
Eric

FWIW, we didn't change anything with regards to OOB and TCP from 1.2.6
-> 1.2.7, but it's still good to be at the latest version.
Try running with this MCA parameter:
mpirun --mca oob_tcp_listen_mode listen_thread ...
Sorry; I forgot that we did not enable that option by default in the
v1.2 series.
