Hi,

  Crafty has not been designed to run on numa - the current version will choke
as number of processors increase.
The way search is getting split , memory and cache affinity , etc will have to
be taken into account. Also it may have to stop using threads and move towards
processes.
These maybe the basic changes - so as you can see - huge rewrite that "may"
degrade perf on non-numa machines.
