ABSTRACT:
A task control mechanism for maintaining a queue of ready or available processes linked together according to an assigned priority for a plurality of central processors where the processors may be assigned to the highest priority task when that processor is not busy executing some higher priority task. The task control mechanism also includes a mechanism for computing task priorities as new tasks are inserted into the queue or removed. The mechanism also maintains an event table which is really a table of event designations to be allocated to different processes upon request where the requesting processes assign a particular function or "meaning" to the event designation. The mechanism of the present invention maintains the state of such allocated events in the event table and signals the related (or "waiting") processes that an event has happened so that the particular system central processors assigned to execute those particular processes may then proceed with their execution.
