Go up one level in this thread
There are a few chess engines that work by message passing. A few by distributed memory. Some mix both. But a SMP eight processor system won't be eight times as fast as an uniprocessor anyways. The current chipsets are horrible and the Intel SMP protocol is atrocious. And the amount of duplicate work will increase by a large factor. As to answer the question of running an unmodified parallel program. The OS will have a SMP driver, that translates a logical SMP system to the actual NUMA. Thats not an ideal way to do it, better to go physical. But the Hammer has such a fast memory system that first order NUMA optimizations will be unnecessary. And there is no reason not to believe that it will in any way impact performance. The many memory banks will increase memory bandwidth and most probably help speed up HT access. MvH Dan Andersson
