A proof technique for parallel programs. (English) Zbl 0543.68010
Summary: In this paper we present a set of axioms and rules of inference for a parallel programming language with shared variables and synchronization statements. The important difference between our approach and that of S. Owicki and D. Gries [Commun. ACM 19, 279-285 (1976; Zbl 0322.68010)] is that our semantics does not contain anything similar to their ’inference freedom’ check, resulting in a much greater isolation of the proofs of the individual processes than is possible in their system. We illustrate our proof technique with some simple examples.
