I think you are wrong here Ben or at least you are missing one serious problem. As far as I know the GP fitness evaluation code is a largely branching stuff that can hardly be vectorized and the SPEs have weak or no branch predictor at all and small cache and are good precisely at the other kind of code, namely highly vectorized code with few branching points. I would not be surprised if it turned out that with the type of code you have to execute to do GP fitness evaluation the SPEs will be 10 times slower than an Athlon processor and the whole gain from having 8 such units will be lost. So it is not just the memory issue -- look at the processing speed as well. - lk ------- To unsubscribe, change your address, or temporarily deactivate your subscription, please go to http://v2.listbox.com/member/[EMAIL PROTECTED]
