Core dumps are your friends (though most linux distros turn them off by default now). That and compiling your code with symbols, and debugging enabled. I rather enjoy (ok, I really don't) pulling up crashed binaries, loading up the core, and walking the stack backwards to see the real reason for the crash. Oddly enough I am doing that now for an MPI code (sigh). > > thanks > mat > _______________________________________________ > Beowulf mailing list, Beowulf at beowulf.org > To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf -- Joseph Landman, Ph.D Founder and CEO Scalable Informatics LLC, email: landman at scalableinformatics.com web : http://www.scalableinformatics.com phone: +1 734 786 8423 fax : +1 734 786 8452 or +1 866 888 3112 cell : +1 734 612 4615
