Simulation facility for development of high level control code at the SSC

Abstract An interactive simulator has been built to serve as a development platform for High Level Application Code (HLAC). It is built around a powerful parallel computer that serves as a particle tracking engine. An intermediate hardware and software layer incorporates fully the EPICS control system. Details of the control system are hidden from the HLAC by an isolation layer (AIC) which consists of C++ class libraries. A closed orbit correction module developed on the simulator is described.
