This paper presents a distributed implementation of the Structured Gamma programming language, a language based on the Gamma multiset rewriting paradigm. Structured Gamma offers, in addition to the advantages introduced by Gamma, implicit concurrent behavior and a type qstem where not onlv types themselves are defined but also the automatic venfication of user defined types at compilation time. Problems and mechanisms involved in a MPI-based implementation of Structured Gamma using a type checking engine based on MGU -Most General Unifier are investigated.
