I believe that speedup table is what count here. And it is geniune. And there *is* way to obtain anyone's Ph.D. thesis in the USA, and Bob mentioned it several days ago. BTW, I don't see why majority of code in CopyToSMP() should be done under lock. All that should be done under lock is the assignment "c->used=1;". After that you should release the lock. I would not be surprised if it'll speed up the search with many (>= 16) CPUs. Personally, I'd replaced loops that copy data by memcpy() calls where possible. That's not Fortran, and compiler should generate the code that works for the memory-aliased case; by using memcpy() instead of loop you are telling the compiler that there are no aliases. And of course "used" should be declared "volatile". [Bob, do you read that]?
