cluster could be added to an S-MP system. The S-MP was originally designed by FPS Computing as the FPS Model 500EA. FPS were acquired by Cray Research in 1991, becoming Cray Research Superservers Inc., and the Model 500EA was relaunched by Cray in 1992 as the S-MP. The S-MP was a short-lived model, and was superseded by the
