Paul, serious question for you: What do you think the Itanium will be (s) best suited for? I do a lot of double precision fp-intensive (quantum) calculations (on huge datasets) and was wondering whether the Itanium (or McKinley) would be suited for that. I would love to be able to use MP Xeon boxes, but the problem is that the P6 core just isn't very good at double precision (it runs the calculations in question roughly half as fast as a K7). I was going to build a cluster of Athlons, but I've been really bogged down with other matters and haven't gotten around to it yet. I'm also considering the P4. There's plenty of ILP (and thread-level same) in the calculations, so SSE2 might be the way to go... (I don't want to rewrite the code for only a small boost, so I won't commit to the P4 before seeing some relevant benchmarks). Depending on P4 system price, Athlon clusters might still be the way to go, though... (we're seriously feeling the squeeze around here, having suffered a 25% budget decrease over the past couple of years). TIA, -fyo
