But isn't that only for the 24-bit integer? If you want to multiply full
words you have to (internally) convert to floating point, multiply, and
convert back.

I have dozens of machines that can handle a 16MB computation; I'm not
gonig to bother with a Cray for those. The biggest advantage of the Cray
line (particularly the Cray-2) is its huge address space.

So what's the actual time for multiplying integers?
