Abstract

Theatre is a control-based actor system currently developed in Java, whose design specifically addresses the development of predictable, time-constrained distributed systems. Theatre, though, can also be used for un-timed concurrent applications. The control structure regulating message scheduling and dispatching can be customized by programming. This paper describes a novel implementation pTheatre (Parallel Theatre), whose control structure can exploit the potential of parallel computing offered by nowadays multi-core machines. With respect to the distributed implementation of Theatre, pTheatre is more lightweight because it avoids the use of Java seri-alization during actor migration, and when transmitting messages from a computing node (theatre/thread) to another one. In addition, no locking mechanism is used both in high-level actor programs and in the underlying runtime support. This way, common pitfalls related to classic multi-threaded programming are naturally avoided, and the possibility of enabling high-performance computing is opened. The paper demonstrates the potential of the achieved realization through a parallel matrix multiplication example.
