Yeah, compilers today are no better. We found the limits of statically scheduled parallelism pretty fast. On code that uses static scheduling, a modern OoO processor can easily duplicate what IA64 was capable of (and a pipelined loop using AVX will utterly smoke it), while being far better at all the stuff IA64 failed at.
