Abstract

See full text

A mechanism is provided for biasing placement of a software thread on a currently idle and dispatched processor. The operating system starts with the last logical processor on which the software thread ran and determines whether that processor is idle and dispatched and considers each logical processor until a currently dispatched and idle logical processor is found. If a currently dispatched and idle logical processor is not found, then the operating system biases placing the software thread on an idle logical processor.
