For this application and numerous other similar ones, the x86_64
architecture would be a better choice than the IA64 architecture.

This said, please lets refrain from architecture bashing.  IA64 is well
suited for specific applications, though most tend to be outside of
informatics, as informatics codes tend to fare well on CPUs with
excellent integer performance, speculative execution, and out-of-order
capability.  As it turns out, Opterons and similar x86_64-like
architectures are quite well suited to these codes.
