  A Cray XMP/48 costs ~$14 million.  We have one at school- I can
  see the supercomputer building from my apartment window, the
  illuminated dish pointed at the heavens.

  The XMP/48 is a 4 processor, 8 million 64-bit word computer.  It
  use used mainly for mathematical pipelining.  Various other
  computers are used for support- VAX 11/750,2 11/785s, IBM 4381, 3 PDP
  11's (84s,44s,24s), a Hyper Channel, and various other nets.  The
  point is, a Cray alone is not too productive, so the overall price
  for a system using a Cray is a *lot* more than $14 million. (I
  like to think of the Cray as a math coprocessor!).

  It costs appoximately $2000 a minute per processor to use, or
  $8000/min for all processors...

  I'd still rather have access to the Cray than thousands of Amigas,
  (like where would I put them all?).
