IDIOM: Integrating dependent and-, independent and-, and or-parallelism

Gopal Gupta; Vítor Santos Costa; Rong Yang; Manuel V. Hermenegildo

Independent and-parallelism, dependent and-parallelism and or-parallelism are the three main forms of implicit parallelism present in logic programs. In this chapter we present a model, IDIOM, which exploits all three forms of parallelism in a single framework. IDIOM is based on a combination of the Basic Andorra Model of Warren and the Extended And-Or Tree Model of Chapter 4. Because of the addition of the Andorra Model, IDIOM supports both Prolog as well as the flat concurrent logic languages. We discuss the issues that arise in combining the three forms of parallelism, and our solutions to them. We also present an implementation scheme, based on binding and base arrays, for implementing IDIOM.
