> This removes the need for the hardware to do reordering, and shoves the responsibility for finding parallelism onto the human or compiler, both of which can, presumably, take a more global view of the problem than a piece of silicon can. I think this was proved wrong - the opposite is true; it is incredibly difficult for software to predict the internal state of a CPU at compile time. The silicon is truly the only thing with an accurate account of its internal state ( cache, register renaming, etc ).
