摘要： Managing computer memory in a computer with dynamic logical partitioning that operates transparently with respect to operating systems in logical partitions. Exemplary methods, systems, and products are described for managing computer memory in a computer with dynamic logical partitioning that include copying by a hypervisor, from page frames in one logical memory block (“LMB”) of a logical partition (“LPAR”) to page frames outside the LMB, contents of page frames having page frame numbers in a page table for an operating system in the LPAR. Embodiments typically include storing new page frame numbers in the page table, including storing by the hypervisor, for each page frame whose contents are copied, a new page frame number that identifies the page frame to which contents are copied. In typical embodiments, copying contents of page frames and storing new page frame numbers are carried out transparently with respect to the operating system.

摘要： A method, apparatus, and computer program product are disclosed in a data processing system for providing a virtualized time base in a logically partitioned data processing system. A time base is determined for each one of multiple processor cores. The time base is used to indicate a current time to one of the processor cores for which the time base is determined. The time bases are synchronized together for the processor cores such that each one of the processor cores includes its own copy of a synchronized time base. For one of the processor cores, a virtualized time base is generated that is different from the synchronized time base but that remains synchronized with at least a portion of the synchronized time base. The processor core utilizes the virtualized time base instead of the synchronized time base for indicating the current time to the processor core. The synchronized time bases and the portion of the virtualized time base remaining in synchronization together.

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： 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.
摘要翻译：分区管理器包括I / O重新配置机制和逻辑分区挂起/恢复机制，其协同工作以在逻辑分区的计算机系统中执行自主I / O重新配置。当需要I / O重新配置时，受影响的逻辑分区将被挂起，重新配置I / O，并恢复受影响的逻辑分区。因为逻辑分区在I / O重新配置期间被挂起，所以当I / O被重新配置时可能发生的任何ghost数据包被忽略。

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： 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： Replacing a failing physical processor in a computer supporting multiple logical partitions, where the logical partitions include dedicated partitions and shared processor partitions, the dedicated partitions are supported by virtual processors having assigned physical processors, and the shared processor partitions are supported by pools of virtual processors. The pools of virtual processors have assigned physical processors. Embodiments operate generally by assigning priorities to the dedicated partitions and to the pools of virtual processors; detecting a checkstop of a failing physical processor; retrieving the failing physical processor's state; replacing by a hypervisor the failing physical processor with a replacement physical processor assigned to a dedicated partition or pool, which dedicated partition or pool has the lowest priority among the priorities of the dedicated partitions and pools; and assigning the retrieved state of the failing physical processor as the state of the replacement physical processor.

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.
摘要翻译：一种装置，程序产品和方法支持多线程计算机中数据结构的释放，而不需要使用计算上昂贵的信号量或旋转锁。具体来说，访问数据结构由共享指针控制，当接收到请求以解除分配数据结构时，共享指针最初被设置为指示稍后访问指针的任何线程数据结构不可用的值。此外，为了解决已经拥有共享指针的副本的任何线程，并且因此能够在请求启动之后通过共享指针访问数据结构，所有这些线程被监视以确定是否有任何线程仍在使用该共享指针通过确定任何线程是否正在执行能够使用共享指针来访问数据结构的程序代码。一旦满足此条件，就确保没有线程可以通过共享指针潜在地访问数据结构，因此可以解除分配数据结构。
