TI SMACK: The Smalltalk Actor Kernel AU Trevor P. Hopkins LT UMCS-88-12-2 OR UMCS AV http http://www.cs.man.ac.uk/cstechrep/Abstracts/UMCS-88-12-2.html AV email techreports@cs.man.ac.uk MN December YR 1988 AB There has been increasing interest in recent years in concurrent object-oriented systems: systems in which at least some of the objects can be `active' concurrently, and (typically) can continue processing after a message send. The aim is to be able to express algorithms and applications in a concurrent manner which can be exploited by aparallel computer system. _ This report considers `actors' systems, and describes an implementation of an actor computational model. It further discusses various implementation techniques for actor programming languages on realistic large-scale parallel computers.
