Parallel Task Execution in a Decentralized System.

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.
