【Abstract】 In exact computation, a number of problems exist, the solution to which demands an exhaustive search and hence a great deal of computing time. This paper deals with a tree-structured multiprocessor system for combi- patorial Computing. Each node of the system consists of a mini-or micro- processor with sufficient memory to run independently. Each processor can be a master or a slave or both. A master assigns tasks to the slaves and subsequently obtains results from them. The user expresses the problem being solved in a high level language called PASCAL-C. This is conventional PASCAL with a number of additional constructs. The syntax, semantics and implementation of PASCAL-C are specified, and an example program written in PASCAL-C is presented.更多还原
