At SC13 there was a talk by Laxmikant Kale from UIUC about CHARM++ (used by NAMD for instance) at the "Practical Fault Tolerance on Today's HPC Systems" tutorial which sounded like it had the abilities to cope with faults as it is more a computational workload distribution system (going on what was said about it). Now you can build CHARM++ to use MPI as its underlying mechanisms but I don't know how well it copes with failures in that mode. cheers, 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/ iEYEARECAAYFAlMX4NMACgkQO2KABBYQAh8uyACgk2t3COaBalPC/Lt5TT+/nrxW X08An3ZPJXa7FuaXsWWua3h6sw+S9r3A =KKKM -----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
