I used to design micros, and I used to design workstations, too.
What they're capable of now, and where they're going in the 
performance space, isn't the constant source of surprise you imply.

I have yet to brag about anything here.  This is comp.arch, not 
comp.marketing.  Marketing and market success are peripheral issues
which I have no interest in pursuing in this forum.  Or do you think
that you have to make a lot of money off something before it can be
considered technically important?  

What interests me is building fast computers.  To that end, Multiflow
has contributed something original and innovative, and as far as I can
tell, multiple-instruction issue is a path that seems to be gaining
adherents, especially among the very micros I'm supposed to be terrified
of.  From a comp.arch point of view I think that's neat.

We've been through this before.  When micros want to supplant the high-end
supers, they'll have to come up with answers to the age-old (well, ok, 
maybe 15 years old) problem of how to build a memory that will keep a fast
CPU fed.  Such a memory costs a Whole Lot Of Money.  When you've sunk a lot
of money into that memory, you can afford more CPU than you can buy off the
shelf.  There *is* some question about how fast one can turn out specialized
processors vs. how fast the micro guys can crank them out.  (It's clear who's
winning that race for certain data points such as Cray vs. Moto/Intel, 
though.)

But you do have a point (whether it's the one you intended, I don't know).
If LLNL personnel are getting their work done on workstations, maybe the
market for true supercomputer performance (for which you need the
kind of memory and I/O bandwidth I referred to above) isn't as big as 
people have always thought it was.  Or their workloads have migrated away
from the canonical vector codes to codes that no longer show off the big
supers to their best advantage?  If either of these is true, then you're
right, this presages a major shift in what hardware people buy.
