Process suicide upon thread death

Is there a way to get one thread to signal its parent (and preferably
other threads) that it's dying to a fault like SIGBUS or SIGSEGV? I'm
doing some software fault injections on a multi-threaded MPI program
and I'm finding that while the fault will kill a particular thread
PID, the rest of the application will continue on, even in a
compromised condition. I would much prefer that a dying thread
"broadcast" to other threads and/or parent that they need to exit too
so the entire application dies (and can be restarted). Before trying
to cobble together something, I thought I'd ask if there was a built
in mechanism.

Thanks!

There is no a built-in mechanism for this AFAIK. You will have to change your code to pass the returning signal of dying processing to the parent, or keep some temp file to signal the health status of forked processes. Coding complexity will depend on your specific needs.
