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.

摘要： Management of a UNIX-style storage pools is enhanced by specially managing one or more memory management inodes associated with pinned and allocated pages of data storage by providing indirect access to the pinned and allocated pages by one or more user processes via a handle, while preventing direct access of the pinned and allocated pages by the user processes without use of the handles; scanning periodically hardware status bits in the inodes to determine which of the pinned and allocated pages have been recently accessed within a pre-determined period of time; requesting via a callback communication to each user process to determine which of the least-recently accessed pinned and allocated pages can be either deallocated or defragmented and compacted; and responsive to receiving one or more page indicators of pages unpinned by the user processes, compacting or deallocating one or more pages corresponding to the page indicators.

摘要： Automated techniques ensure that system central processing unit (“CPU”) power is not a bottleneck when migrating logical partitions from one system to another system or systems (e.g., in the event of a system evacuation). CPU resources needed to fully drive available bandwidth during the migration are computed. CPU resources of the system are then adjusted for the migration, which may comprise scaling down the CPU resources that are guaranteed for the executing partitions and/or adjusting relative partition variable weights to limit the amount of excess capacity that can be allocated to a partition.

摘要： A technique for determining placement fitness for partitions under a hypervisor in a host computing system having non-uniform memory access (NUMA) nodes. In an embodiment, a partition resource specification is received from a partition score requester. The partition resource specification identifies a set of computing resources needed for a virtual machine partition to be created by a hypervisor in the host computing system. Resource availability within the NUMA nodes of the host computing system is assessed to determine possible partition placement options. A partition fitness score of a most suitable one of the partition placement options is calculated. The partition fitness score is reported to the partition score requester.

摘要： Systems, methods and computer program products may provide managing utilization of one or more physical processors in a shared processor pool. A method of managing utilization of one or more physical processors in a shared processor pool may include determining a current amount of utilization of the one or more physical processors and generating an instruction message. The instruction message may be at least partially determined by the current amount of utilization. The method may further include sending the instruction message to a guest operating system, the guest operating system having a number of enabled virtual processors.

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： 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.

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.
