This is all in shared memory on a MacBook Pro; no networking involved.
The seg fault with the code example above looks like this:

Try upgrading to the v3.0, or at least to the latest in the v2.x series. The
v1.10 series is legacy and no longer maintained.

Hi,
I am finding that on Ctrl-C, mpirun immediately stops and does not sends
SIGTERM to the child processes.
I am using openmpi 1.10.6.
The child processes are able to handle SIGINT. I verified that by a printf in
my signal handler and then issuing SIGINT to my process directly. However, when
Hi Howard/OpenMPI Users,
I have had a similar seg-fault this week using OpenMPI 2.1.1 with GCC 4.9.3 so
I tried to compile the example code in the email below. I see similar behavior
to a small benchmark we have in house (but using inc not finc).
When I run on a single node (both PE’s on the sa
I believe that map-by core with a PE > 1 may have worked at some point in the
past, but the docs should probably be looked at. I took a (very brief) look at
the code and re-enabling that particular option would be difficult and not
really necessary since one can reproduce the desired pattern wit
