Is this a fair statement?  I've played some with the i860 and
I can write (by hand so far) code that is pretty fast.
However, the programs where it really zooms are vectorizable.
That is, I can make this micro solve certain problems well;
but these are the same problems that a vector machines handle well.

Getting good FP performance from a micro seems to require
pipelining.  Keeping the pipe(s) full seems to require a certain amount
of parallelism and regularity.  Vectorizable loops work wonderfully well.

Perhaps I've misunderstood your intent, though.  Perhaps you meant 
that an i860 (or Mips or whatever) can outrun a Cray (or Nec or whatever) 
on some programs.  I guess I'm still doubtful.  Do you have examples
you can tell us about?

Thanks,
