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.
