looks good. performance per dollar is quite bad with a GTX295 though. 2 GTX260 with 432 cores together cost 260Eur and a GTX295 with 480 cores costs 370Eur. the 295 only occupies 2 slots instead of 4 with 2 GTX260 though. > > Would using 2 increase (double?) performance? scales linearly. http://en.wikipedia.org/wiki/Embarrassingly_parallel > > What countigous Disk size should I look into? a single table occupies around 6gb, you can expect to fill 12gb per month with a GTX295. For the sorting you may need another 6 or 15gb of temp storage. that depends whether we dump stxxl which is slow and hungry (in the way it is used now) for our own sorter implementation. > > Jon > _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
