Since this system is not using SMP (right?), you still have code that could run on non-SMP-based super computers. Do you plan to update/revive Cray Blitz for those machines or change Crafty? The reason I am asking is that SMP has to share its memory space while other architectures do not suffer under the limitations of accessing the same memory blocks with multiple CPUs but can dedicate their fullest potential to their own memory sub-system. For chess this might be a great improvement. No? Gregor
