Abstract

Driving task dispatching by an operating system in a multiprocessor computer system is accomplished with a virtual switching queue which accepts highest priority tasks from multiple switching queues which in turn are accessed by instruction processors seeking tasks. Overload, plucking and stealing of tasks may be used to effectively balance load within the computer system. Dynamic reconfiguration used where regular queues lose underlying instruction processors.
