Crayon

krā-ˌän

n. 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 (sense 2) 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 that derives from an old Crayola crayon promotional gimmick: When you buy 64 crayons you get a free sharpener.
