摘要： A logically-partitioned computer, program product and method utilize a flexible and adaptable communication interface between a partition and a partition manager, which permits optimal handling of partition management operations such as state change operations and the like over a wide variety of circumstances. In particular, a partition is permitted to indicate, in connection with a request to perform a partition management operation, whether an asynchronous notification should be generated or suppressed in association with the performance of the partition management operation by a partition manager. As a result, asynchronous notifications are selectively generated in association with the performance of partition management operations based upon indications in the requests made by partitions for such operations.

摘要： A method, apparatus, and computer-usable medium for predicting capacity on a data processing system. According to a preferred embodiment of the present invention, a capacity manager estimates an incremental power value utilize for activating and maintaining an additional processor in the data processing system. The capacity manager calculates a power headroom value. In response to calculating the power headroom value, the capacity manager determines whether an adjustment power headroom value is required. The capacity manager calculates a projected capacity value added by the additional processor to the data processing system.

摘要： A method, apparatus, system, and signal-bearing medium that, in an embodiment, calculate a preemption credit for a partition if a virtual processor is preempted and the partition is unable to receive an entitled capacity of physical processor cycles during a dispatch window. The preemption credit is the portion of the entitled capacity that the partition is unable to receive. As long as the partition has a remaining preemption credit, in subsequent dispatch windows, a portion of the preemption credit is allocated to the virtual processor, and the preemption credit is reduced. In this way, in an embodiment, shared processor partitions may be ensured of receiving their entitled allocation of processor cycles.

摘要： A system, computer program product and method of logically partitioning a multiprocessor system are provided. The system is first partitioned into a plurality of partitions and each partition is assigned a percentage of the resources of the system. However, to provide the system with virtual machine capability, virtual resources, rather than physical resources, are assigned to the partitions. The virtual resources are mapped and bound to the physical resources that are available in the system. Because of the virtual machine capability of the system, logical partitions that are in need of resources that are assigned to other partitions are allowed to use those resources if the resources are idle.

摘要： An apparatus, program product and method guarantee a period of time in which a partition's use of a resource will not be preempted by a hypervisor. An inquiry communication from the partition prompts the hypervisor to determine if work is pending for the hypervisor. If not, the hypervisor sends a guarantee response ensuring the period of uninterrupted use of the resource by the partition.

摘要： An apparatus, program product and method distributes work within a logically partitioned computer system by binding a virtual processor or other resource of a hypervisor partition to a partition or physical resource. The partition or physical resource to which the virtual resource is bound is the same partition or physical resource upon whose behalf the hypervisor resource does work. The partition requesting work of the hypervisor partition is thus penalized by virtue the virtual resource using a physical resource owned by the requesting partition.

摘要： A processor allocation mechanism for a logically partitionable computer system allows an administrator to specify processing capability allocable to each partition as an equivalent number of processors, where the processing capability may be specified as a non-integer value. This processing capability value is unaffected by changes to the processing capability values of other partitions. The administrator may designate multiple sets of processors, assigning each physical processor of the system to a respective processor set. Each logical partition is constrained to execute in an assigned processor set, which may be shared by more than one partition. Preferably, the administrator may designate a logical partition as either capped, meaning that a partition can not use excess idle capacity of the processors, or uncapped, meaning that it can.

摘要： Disclosed is a computer implemented method, computer program product, and apparatus to establish at least one paging partition in a data processing system. The virtualization control point (VCP) reserves up to the subset of physical memory for use in the shared memory pool. The VCP configures at least one logical partition as a shared memory partition. The VCP assigns a paging partition to the shared memory pool. The VCP determines whether a user requests a redundant assignment of the paging partition to the shared memory pool. The VCP assigns a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment. The VCP assigns a paging device to the shared memory pool. The hypervisor may transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.
