Computational physics pretty much demands this. > Once you've got a generalized fast approach using message passing, it's > very scalable. But the human programming doesn't scale across 10^6 to asynchronous 10^9 nodes with <GByte of memory each and where determinism is computationally more expensive than stochastical good-enough result. Of course the physical modelers won't bat an eyelash, but the common programmer who still tries to figure out this multithreading thing will be out to lunch. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
