More Information
Summary:The present invention provides a computer implemented method and apparatus to assign software threads to a common virtual processor of a data processing system having multiple virtual processors. A data processing system detects cooperation between a first thread and a second thread with respect to a lock associated with a resource of the data processing system. Responsive to detecting cooperation, the data processing system assigns the first thread to the common virtual processor. The data processing system moves the second thread to the common virtual processor, whereby a sleep time associated with the lock experienced by the first thread and the second thread is reduced below a sleep time experienced prior to the detecting cooperation step.
