Mechanism to schedule threads on os-sequestered without operating system intervention

Abstract

Method, apparatus and system embodiments to schedule OS-independent 'shreds' without intervention of an operating system. For at least one embodiment, the shred is scheduled for execution by a scheduler routine rather than the operating system. A scheduler routine may run on each enabled sequencer. The schedulers may retrieve shred descriptors from a queue system. The sequencer associated with the scheduler may then execute the shred described by the descriptor. Other embodiments are also described and claimed.

Description

[0001] This application is a divisional application of a patent application with an application date of December 22, 2005, an application number of 200580045758.6, and an invention title of "Mechanism for Scheduling Threads on an OS Isolation Sequencer Without Operating System Intervention". technical field [0002] The present disclosure relates generally to information handling systems, and more particularly, to scheduling and control of thread execution on an OS isolation sequencer without operating system intervention. Background technique [0003] To enhance the performance of information handling systems, such as those that include microprocessors, hardware and software techniques are employed. On the hardware side, microprocessor designs that improve microprocessor performance include faster clock speeds, pipelining, branch prediction, superscalar execution, out-of-order execution, and cache memory. Many of these approaches result in an increase in transistor count, a...

Problems solved by technology

In general, however, operating system control does not scale well; the ability of an operating system application to schedule threads without negatively impacting performance is usually limited to a small number of threads
