Yes, and you are arguing for massive parallelism, for "active memories", in short, for something like the Connection Machine. A hyperactive RISC machine probably won't be any better at these problems than the CRAY. The complexity is too great. Besides, look at the most obvious problem: why pay megabucks for a big, fast, completely underutilized memory? Balancing computation and I/O is not enough; we must balance these with the amount of memory available.
