[Beowulf] itanium vs. x86-64

[Toon Knapen]

Recently it was anounced that the tukwila suffers yet another delay.

I have been working on itanium machines for a year now and I actually found
the hw pretty elegant and the dev software stack on top of it (compiler,
profiler etc) pretty handy. I might go back to x86-64 however because of
their price/performance.

IMO, the itanium mostly lacks memory-bw in comparison to Xeon's and Opterons
but now with the Tukwila switching to the QuickPath, how do you guys think
Itanium will perform in comparison to Xeon's and Opteron's ?

thanks in advance,

toon
