Multithreaded Synchronous Data Flow Simulation

This paper introduces an efficient multithreaded synchronous dataflow (SDF) scheduler that can significantly reduce the running time of multi-rate SDF simulations on multiprocessor machines with only a slight increase of memory usage over standard cluster loop scheduler[1]. Experiments run on a dual processors machine achieves on average approximately 146% increase in performance with less than 2.4% increase in memory usage. There is an average of 2x speedup with a quad processors machine.
