1. Someone who works on Cray supercomputers. More specifically, it implies a
programmer, probably of the CDC ilk, probably male, and almost certainly wearing
a tie (irrespective of gender). Systems types who have a Unix background tend
not to be described as crayons.
2. A computron that participates only in number crunching.
3. A unit of computational power equal to that of a single Cray-1. There is a
standard joke about this usage that derives from an old Crayola crayon
promotional gimmick: When you buy 64 crayons you get a free sharpener.
