ABSTRACT:
In order to process a program by parallel processing using a plurality of processors, the program is divided into a plurality of partial programs. Then one or more expressions are derived, the or each expression expressing a relationship between the partial programs, such as which can be executed independently and which require the execution of another partial program. The expression or expressions can then be investigated to determine which has a desired characteristic, such as a characteristic corresponding to uniform loading of the processors. The expression can also be varied, to give more options for the selection of the expression with the desired characteristic. Then the partial programs can be distributed to the processors on the basis of the relationship corresponding to the expression which has the desired characteristic. Furthermore, when the partial programs are being executed by the processors, any processor which has completed its processing broadcasts a signal to the other processors, which may then re-assign one or more of their partial programs. In this way, parallel processing can be carried out quickly, with substantially uniform loading of the processors.
