摘要： A mechanism is provided for determining whether to use cache affinity as a criterion for software thread dispatching in a shared processor logical partitioning data processing system. The server firmware may store data about when and/or how often logical processors are dispatched. Given these data, the operating system may collect metrics. Using the logical processor metrics, the operating system may determine whether cache affinity is likely to provide a significant performance benefit relative to the cost of dispatching a particular logical processor to the operating system.

摘要： 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.

摘要： A method, a system and a computer program product for controlling the hardware priority of hardware threads in a data processing system. A Thread Priority Control (TPC) utility assigns a primary level and one or more secondary levels of hardware priority to a hardware thread. When a hardware thread initiates execution in the absence of a system call, the TPC utility enables execution based on the primary level. When the hardware thread initiates execution within a system call, the TPC utility dynamically adjusts execution from the primary level to the secondary level associated with the system call. The TPC utility adjusts hardware priority levels in order to: (a) raise the hardware priority of one hardware thread relative to another; (b) reduce energy consumed by the hardware thread; and (c) fulfill requirements of time critical hardware sections.

摘要： Illustrated embodiments provide a computer implemented method and data processing system for redispatching a partition by tracking a set of memory pages, belonging to the dispatched partition. In one illustrative embodiment the computer implemented method comprises finding an effective page address to real page address mapping for a page address miss in response to determining the page address miss in a page addressing buffer, and saving the mapping as an entry in an array. The computer implemented method creates a preserved array from the array in response to determining the dispatched partition to be an undispatched partition. The computer implemented method further analyzes of the preserved array for a compressed page in response to determining the undispatched partition is now redispatched, and decompresses the compressed page prior to the partition being redispatched.
