One of the big advantages with Tesla is the use of registered memory for the GPU. This significantly reduces the risk of a bad memory bit screwing up your calculations, and the hardware can let you know if such an error exists. ATI doesn't offer this feature on any of their boards, and that is pretty much the reason for them being absent from the HPC space, despite having better performance in relation to both price and power. f _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
