This paper presents a contribution to this area, as far as logic programming on a distributed execution environment is concerned. We discuss the main issues on the design and implementation of the logic programming language Delta Prolog [2] [3] [6] [7] [11], extending Prolog with constructs for concurrency and communication. The work described is one of the research components of a project on the development of mechanisms for parallel logic programming support on parallel architectures, currently running in this University [8]." }
