Yes, and you have obviously failed to consider what role the hardware plays in a chess program _and_ the specifics of the hardware we're discussing (Hammer). >At least for those of us that don't just throw an algorithm onto a machine >with no regard for reasonable performance. And _performance_ is what a The highest-latency memory in a Hammer system will be no slower than all the memory in an Intel system. So if you "just throw an algorithm onto" a Hammer system, it will almost certainly run faster than an Intel system. So unless your performance is unreasonable on Intel (?), you CAN expect reasonable performance on a Hammer and you are not REQUIRED to do anything to get it. -Tom
