[OMPI users] signal handling with mpirun

[Kulshrestha, Vipul]

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 I send the same signal to mpirun process (or press Ctrl-C), it stops right away and my processes do not receive any signal.

I suspect that I may be doing something wrong, but need some help to troubleshoot this.

Thanks,
Vipul

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 The v1.10 series is legacy and no longer maintained.
