Whether or not the Cray-3 is manufacturable, there will certainly be super-
computers with many gigaflops of VECTOR performance in the near term.  We were
talking about scalar performance, and not vector performance.  Certain codes
which are heavily run on Cray machines are scalar and would score high hit
rates in a rather small cache.  I predict that a microprocessor will outrun the
scalar performance of the Cray-1S within a year.   The "supercomputers" will
only hold on for those applications which are 99% vectorized, which are darned
few, and because of this supercomputers will share the computer center floor
with micro based hardware soon, and on an equal footing.



Is the news software incompatible with your mailer too?
