Writing Concurrent Object-Oriented Programs using Smalltalk-80

Writing Concurrent Object-Oriented Programs Using Smalltalk-80

This paper considers a number of ways in which concurrent programs may be expressed within an object-oriented framework. It goes on to describe work investigating the expression of highly parallel programs in a conventional object-oriented language (Smalltalk-80). The relevance of this work to a new parallel object-oriented system is discussed. An implementation of an ‘eager’ evaluator is descr...

On Concurrent Execution of Object{oriented Programs

In this paper, we introduce object{oriented programs as sets of communicating objects. We investigate possibilities for their concurrent execution, starting with a review of existing concurrent, object{oriented systems. Most of these systems introduce new programming{language features, forcing a programmer to control concurrency by hand. In contrast, we prefer automatic parallelization of progr...

Static Slicing of Concurrent Object-Oriented Programs

Program slicing has many applications such as program debugging, testing, maintenance, and complexity measurement. This paper concerns the problem of slicing concurrent object-oriented programs that has not been addressed in the literatures until now. To solve this problem, we propose a new program dependence representation named the system dependence net (SDN), which extends previous program d...

Systematic Development of Concurrent Object-Oriented Programs

Using Re ection for Checkpointing Concurrent Object Oriented Programs

This paper presents a re ective approach to checkpointing concurrent object oriented programs. We describe a checkpointing and rollback library for multithreaded programs written in C++. We demonstrate some of the unique features o ered by this library, such as selective checkpointing and selective rollbacks of threads of a process that are achievable only through the use of re ection.
