cray /kray/ n.  1. (properly, capitalized) One of the line
   of supercomputers designed by Cray Research.  2. Any supercomputer
   at all.  3. The {canonical} {number-crunching} machine.

   The term is actually the lowercased last name of Seymour Cray, a

   by Cray Research brass to shape their corporate culture and image.
