<IA-64 explained> - yes, a good read. The thing that surprised me most was the specINT and specFP scores which, even if Itanium could run at 1.1 GHz, would only equal an Alpha. Itanium is designed to do up to three instructions per clock, but it appears that its not happening yet, whether due to poor compilers or dependencies in the code is unknown at this point. My guess is code dependencies have more to do with it than poor compilers. If computer programs were defined by dataflow diagrams rather than linear code, exploiting the possibilities for parallelization would be much more successful. That applies to both multiprocessor systems (like the multi-CPU Sledgehammers coming up) and to EPIC (explicitly parallel instruction computing). Petz
