Superscalar technology... not the same thing... superscalar tries to extract instruction parallelism without programming assistance. But no one is building 8-way or 16-way superscalar processors because they don't pay off. But an SMP system with 16 processors can deliver really fast performance for a program that does a parallel search itself, rather than relying on the hardware to execute a few instructions in parallel each cycle. IE it is not easy to keep even two superscalar pipes fed. 4 is harder. 8 probably won't ever be built...
