supercomputer

   <computer> A broad term for one of the fastest computers
   currently available.  Such computers are typically used for
   {number crunching} including scientific {simulations},
   (animated) {graphics}, analysis of geological data (e.g. in
   petrochemical prospecting), structural analysis, computational
   fluid dynamics, physics, chemistry, electronic design, nuclear
   energy research and meteorology.  Perhaps the best known
   supercomputer manufacturer is {Cray Research}.

   A less serious definition, reported from about 1990 at The
   {University Of New South Wales} states that a supercomputer is
   any computer that can outperform {IBM}'s current fastest, thus
   making it impossible for IBM to ever produce a supercomputer.
