....and extensible than if they were just simple primitives of a programming language. Furthermore, it is relatively easy to build up on the basic standard library of concurrency classes to construct more sophisticated concurrency and synchronization abstractions [18] Examples are in the Simtalk [8] or Actalk [16, 17] frameworks. Figure 1 shows a sample of the hierarchy of activity synchronization classes provided by Actalk libraries. They implement various synchronization schemes, such as guards, abstract states, synchronization counters. see in Sect. 4.4) Within the Actalk project, ....

....virtual machine, but we want to propose a minimal extension needed to introduce and study concurrency (i.e. potential parallelism as opposed to physical parallelism) into Smalltalk 80. This approach of studying concurrency models and constructs as an extension of Smalltalk 80 is also advocated by [B ezivin 87] But in contrast, our approach is speci cally related to our concern with the actor paradigm for Object Oriented (or Object Based) Concurrent Programming [OOCP 87] Smalltalk 80 appears to be a wonderful language to explain and discuss the actor languages, with some impressive economy of tools. ....

For concurrency abstractions, an example is the Simtalk platform [B ez 87] which implements and classifies various synchronization and simulation abstractions (Hoare monitors, Kessels monitors, pessimistic or optimistic simulation objects: upon Smalltalk standard abstractions classes.

....question of their cohabitation with standard Smalltalk 80 objects, and by going further, their complete combination within the current Smalltalk 80 environment and methodology. This issue of combining passive objects with active objects is one of the fundamental issue of OOCP, as pointed out by [B ezivin 87, page 404] In order to ensure safety of combination of our actor kernel and Smalltalk 80 we will sketch some methodological rules. It is time now to summarize our goals: 1. preservation, there should be no change made to Smalltalk 80. The system consists in a small extension (a set of classes ....

Some applications are: encapsulation of objects for monitoring and atomicity [Pascoe 86] modeling various communication protocols [B ezivin 88] meta simulation (simulation of simulation models) B ezivin 87] serialization of objects [Yokote and Tokoro 87] and [B ezivin 88] and forwarding of messages to remote objects in a distributed implementation [McCullough 87] and [Bennett 87] Following this technique, we redefine the doesNotUnderstand: method in the class Actor: Actor methodsFor: message ....
