This report describes a run-time system to support Program Composition Notation (PCN), a high-level concurrent programming notation. The run-time system is described in terms of an abstract machine. We specify an abstract architecture that represents the state of a PCN computation and executes abstract machine instructions that encode tests on or modifications to the computation state. Programs to be executed on the abstract machine are encoded as sequences of abstract machine instructions. The abstract machine may be implemented by an emulator written in a low-level language. Alternatively, sequences of abstract machine instructions may be further compiled to machine code. The run-time system is designed to run on uniprocessors, multiprocessors, and multicomputers. 4 refs., 2 figs., 1 tab.
