<combjelly: It is my perception that to truly take advantage of SSE2 in anything but a very samll subset of programs, there will be a need to make fundamental changes to the way programs are structured.> Well, SSE is probably more widely applicable than SSE2. Remember, SSE2 is double precision fp and some 128bit integer (a replacement for MMX, would be my interpretation). SSE can dramatically speed up single precision fp, which is very widely used and often has a relatively high degree of (IL-)parallelism. The (software) prefetch commands are also "SSE1". What we need are basically two things: - Compilers need to be a heck of a lot smarter. - The standard libraries (both public and company-specific) need to be upgraded. The latter of the two is happening... slowly, but it is happening. As for smarter compilers... well, I'm sorry to say that's in the hands of Microsoft. I do wish someone else would come along and make some really great compilers... -fyo
