An exxution model for distributed object-oriented computation

Abstract

This paper describes an execution model being developed for distributed object-oriented computation in a message-passing multiple-instruction/multiple-data-stream (MIMD) cmimun. The objective is to execute an object-oriented pogrum S concurrently as possible. Some opportunities for cmmmenq can be identified explicitly by the programmer. Chehers can be identified at compile time. There are some opportunities for concumncy. however, that can only be discovered atnmtime because they are datadependent. The model of execution we describe attempts to discover and exploit the data-dependent concumncyrhatexistsina given program execution.
