Oops, forgot this in my previous email - I stumbled across the Uni of Tenessee's ULFM (User Level Failure Mitigation) project which has a Wordpress blog here: http://fault-tolerance.org/ There is the PDF for a two page flyer from SC13 on the site which gives an overview and describes it thus: http://fault-tolerance.org/wp-content/uploads/2013/12/SC13-ULFM.pdf # User Level Failure Mitigation is a set of MPI interface extensions # enabling Message Passing programs to restore MPI communication # capabilities affected by process failures. It supports rebuilding # communicators, RMA windows and I/O Files All the best, Chris - -- Christopher Samuel Senior Systems Administrator VLSCI - Victorian Life Sciences Computation Initiative Email: [email protected] Phone: +61 (0)3 903 55545 http://www.vlsci.org.au/ http://twitter.com/vlsci -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlMX4kMACgkQO2KABBYQAh9iXgCffxwP07z91by2FCHxVRwtTl4Q yTUAni3Xn0C+Nla0rS4HwW2dfF4Czb0Q =yWTJ -----END PGP SIGNATURE----- _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
