Integrating Coordination Features in PVM

In this paper we focus on coordination for parallel systems controlled by the PVM software package. We describe several extensions which allow the use of extended coordination features in PVM. The extensions are designed to support coordination metaphors like generative communication or client server programming. They fit into the general philosophy of PVM by adopting an approach to coordination that retains the principles of coordination, while presenting a more pragmatic and traditional interface to the user. 1 Introduction In the area for parallel computing, the aspect of coordination becomes more and more important. This importance has recently been reflected with the development of coordination models and corresponding coordination languages like [Gel89, FA90, JAP93, BH94, JPB90] Although these models deserve a lot of attention from a theoretical point of view, their implementation bears to some performance problems. On the other hand, PVM is an efficient system which allows to p..
