Yeah well i remember negotiating about writing CUDA code for simulation software of something similar. Don't think that this example applies. You want it in RAM for a proper simulation :) _______________________________________________ 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
