another way of looking at itanium is that it's like a multicore processor that is programed with a single instruction stream. given a general-purpose workload, it stands to reason that independent threads are going to be scheduled more efficiently and independent threads can be added at will without changing the architechtural model. so it's also easier to scale. - erik
