Abstract

Concurrent and distributed computing, using portable software systems or environments on general purpose networked computing platforms, has recently gained widespread attention. Many such systems have been developed, and several are in production use. This project proposes the use of object-oriented techniques to enhance application development and ease of use, and to relieve developers of the complexities inherent in message passing environments. We are pragmatic in our objectives; we wish to support the relatively well understood shared-object concurrent computation model while providing facilities designed to aid the programmer with partitioning, scheduling, and synchronization in a straightforward, efficient, and portable manner. In this paper, we describe a shared object toolkit for the PVM distributed computing system, and present preliminary results and experiences. 1 Introduction Concurrent and distributed computing on loosely coupled systems has gained tremendous popularity i...
