Abstract

. This paper investigates the addition of operations for explicit parallelism to the lazy functional language, Gofer. For this purpose, we choose to use a co-ordination language, derived from Linda, based on logically shared associative memories, called spaces. We describe the use of Gofer type classes in building an interface to spaces, which highlights and extends the traditional associative access mechanism. We then show how processes can be added to Gofer, and how we can combine spaces and processes to produce a parallel functional language, which we have called Astro-Gofer. 1 Introduction In this paper, we describe a parallel lazy functional programming language based on the notion of co-ordination[4]. The functional language used is Gofer[8], a dialect of Haskell in which type classes may have multiple type parameters. The co-ordination language is based on shared associative memories called spaces, derived from Linda[4]. 2 Simple Spaces in Gofer We begin with a preliminary e...
