Dear all,
I would like to know if it is possible to enable IPsec in openMPI. I would
like to enable it to do some measurements on the performance. Thanks in
advance.
Regards,
Eisa Al Shamsi
Thank you Jeff for your explaination. It is much clearer now.
Best regards.

Yes, this is a bug. Thanks for identifying the issue!
I have committed a fix to our development tree and have filed to have it moved
into the 1.4 and 1.5 series. You can download a patch for the specific fix
here:

Ouch. These are the worst kinds of bugs to find. :-(
If you attach a debugger to these processes and step through the final death
throes of the process, does it provide any additional insight? I have not
infrequently done stuff like this:
{
int i = 0;
printf("Process %d ready to

Sorry for the delay in replying.
It is probably much easier to NFS share the installation directory so that the
exact same installation directory is available on all nodes. For example, if
you installed OMPI into /opt/openmpi-1.4.2, then make /opt/openmpi-1.4.2
available on all nodes (even if
