MARQUISE was a 1997 technology demonstration conducted by Silicon Graphics/Cray, the Department of Defense, and the University of Maryland, College Park. The achieved goal was to shrink a refrigerator-sized Cray J90 supercomputer to fit in a standard 19-inch rack for use in embedded defense applications aboard an aircraft. The project included research in packaging multiple integrated circuits onto a diamond-substrate multi-chip module (MCM) and spray-evaporative cooling, both of which found use in a later Cray product, the Cray X1.
