Apparently... It has some great ideas implemented, but by the time the first
version came out, IA32 CPUs were much faster anyway. I don't know how
performance compares in *current* IA64 CPUs.
It costs a lot of money.
Most of the optimizing work is left to the compiler, and writing a good
compiler to take advantage of IA64 is really hard (Knuth used the
word "impossible").
