Abstract

The trend towards object-oriented software construction is becoming more and more prevalent, and parallel programming cannot be an exception. In the context of parallel computation, it is often natural to model the computation as message passing between autonomous, concurrently active objects. The problem was, as some previous studies had indicated, that the overhead from message reception to dynamic method dispatching consumes a significant amount of execution time (e.g., as much as 4000 machine cycles or 500 &mgr;seconds at 8 MHz block for some language/hardware combination).
