【Abstract】 The Gamma formalism is a high level parallel programming tool without artificial sequentiality. P. Fradet and D.Le Metayer proposed recently a model of structured Gamma which makes it easy for the programmer to structure the data and to specify particular control strategies. It also makes the automatic analysis of programs easier. Without relying on the “address” concept used by them, a more general form of the structured Gamma is proposed and its syntax and semantics are described in this paper. Types of structured multisets have been discussed at two levels. The author also shows that the new definition keeps the theoretic results, such as static type checking of programs untouched.更多还原
