I had a user grumble about how it was not trivial to get
a basic backtrace on our clusters. his jobs tend to be 32-128p,
and run for a week, so it's not ideal to run them under the debugger.
Using Scali MPI Connect, you can easily install
signal handlers. When the signal(s) is caught,
the application continues to run, the offending
process writes out its registers and you can
conveniently attach it with your favorite debugger.
