Abstract:

A technique is introduced for executing independent segments of a sequentially organized program in a parallel processor environment. A simulator was written to execute a set of program graphs under two different philosophies. In the first, the centralized approach, a processor reverts to operating system control upon completion of an assigned task. In the second, the decentralized approach, a processor always attempts to initiate a ready task before releasing to system control. Within each of these configurations processors are acquired in one of two ways either the operating system polls the program to see if anything is waiting to be done, or the program signals the system when a task becomes ready.
