    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： An apparatus, program product, and method utilize a memory access interrupt to effect a reset of a processor in a multi-processor environment. Specifically, a source processor is permitted to initiate a reset of a target processor simply by generating both a reset request and a memory access interrupt for the target processor. The target processor is then specifically configured to detect the presence of a pending reset request during handing of the memory access interrupt, such that the target processor will perform a reset operation responsive to detection of such a request.

    摘要： An apparatus, program product and method support the deallocation of a data structure in a multithreaded computer without requiring the use of computationally expensive semaphores or spin locks. Specifically, access to a data structure is governed by a shared pointer that, when a request is received to deallocate the data structure, is initially set to a value that indicates to any thread that later accesses the pointer that the data structure is not available. In addition, to address any thread that already holds a copy of the shared pointer, and thus is capable of accessing the data structure via the shared pointer after the initiation of the request, all such threads are monitored to determine whether any thread is still using the shared pointer by determining whether any thread is executing program code that is capable of using the shared pointer to access the data structure. Once this condition is met, it is ensured that no thread can potentially access the data structure via the shared pointer, and as such, the data structure may then be deallocated.

    摘要： A partition manager includes an I/O reconfiguration mechanism and a logical partition suspend/resume mechanism that work together to perform autonomic I/O reconfiguration in a logically partitioned computer system. When I/O reconfiguration is required, the affected logical partitions are suspended, the I/O is reconfigured, and the affected logical partitions are resumed. Because the logical partitions are suspended during I/O reconfiguration, any ghost packet that may occur when the I/O is reconfigured is ignored.

    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.
