| 摘要 |
The present invention provides a computer implemented method, data processing system, and computer program product for mapping and dispatching virtual processors in a data processing system having at least a first partition and a second partition. The data processing system runs a first partition on a virtual processor during a first timeslice. The data processing system identifies an at least one physical page used by the first partition and the second partition. The data processing system maps the at least one physical page to the first partition and the second partition. The data processing system determines a fitness value based on the mapping. The data processing system dispatches the Virtual processor to the second partition on a second timeslice based on the fitness value, wherein the second timeslice immediately succeeds after the first timeslice, whereby the at least one physical page remains in cache during at least the first timeslice and the second timeslice.
