Ok, I can read this at the above link: "DEEP FRITZ Multiprocessor Version Deep Fritz is the multiprocessor version of Fritz and supports one to eight processors. On a dual processsor machine, it will run about 80% faster than on a single." That is a very clear statement. ChessBase says it supports a single processor, but that it was made as a multiprocessor version (the purpose of the program is to run on SMP machines). Being 80 % faster on a dual than on a single, why should it be tested on a single processor? Just to see that it really runs 80% slower? Isn't faster better when we talk about programs? (ok, that's another poll- is faster better or not?) This testing is nonsense, IMHO. That's the same thing of testing a Winboard engine using Shredder's GUI- as we know it has a bug, so the test must wait for the patch. SSDF should test dual versions on dual machines. That's my point of view. Clear and simple. Test dual versions on dual machines. If SSDF don't have dual machines, that's not my fault. Most of us don't have a dual. What about testing it against those single-processor programs using a dual or a quad or a 8-processor machine? Wouldn't that hurt the single-processor program (that can't take advantage of more processors)? So the statement could be different... "WOW! Deep (anything) just beat single (something) , e.g.: 20 - 4 !!!! on a dual!". Pure nonsense, IMHO. A. Ponti
