摘要： A mechanism is provided for transparently consolidating resources of logical partitions. Responsive to the existence of the non-folded resource on an originating resource chip, the virtualization mechanism determines whether there is a destination resource chip to either exchange operations of the non-folded resource with a folded resource on the destination chip or migrate operations of the non-folded resource to a non-folded resource on the destination chip. Responsive to the existence of the folded resource on the destination resource chip, the virtualization mechanism transparently exchanges the operations of the non-folded resource from the originating resource chip to the folded resource on the destination resource chip, where the folded resource remains folded on the originating resource chip after the exchange. Responsive to the absence of another non-folded resource on the originating resource chip, the vitalization mechanism places the originating resource chip into a deeper power saving mode.

摘要： Methods, systems, and articles of manufacture for allowing an update to an executable component, such as a logical partitioning operating system, running on a computer system without requiring a reboot (or IPL) of the computer system are provided. Processors or tasks executing in a portion of code being updated may be forced to a known or “quiesced” state (e.g., designated wait points) before applying the update. If any of the processors or tasks are not in their quiesced state, the update is not applied or may be rescheduled for a later time, in an effort to allow the system to reach the quiesced state.
摘要翻译：提供了用于允许更新在计算机系统上运行的可执行组件（诸如逻辑分区操作系统）的方法，系统和制品，而不需要计算机系统的重启（或IPL）。在更新的代码的一部分中执行的处理器或任务可能在应用更新之前被强制为已知或“静态”状态（例如，指定的等待点）。如果处理器或任务中的任何一个处于静止状态，则不会更新该应用程序，或者可能会在稍后的时间内重新安排更新程序，以使系统达到静默状态。

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： Transparent hypervisor pinning of critical memory areas is provided for a shared memory partition data processing system. The transparent hypervisor pinning includes receiving at a hypervisor a hypervisor call initiated by a logical partition to register a logical memory area of the logical partition with the hypervisor. Responsive to this hypervisor call, the hypervisor transparently determines whether the logical memory is a critical memory area for access by the hypervisor. If the logical memory area is a critical memory area, then the hypervisor automatically pins the logical memory area to physical memory of the shared memory partition data processing system, thereby ensuring that the memory area will not be paged-out from physical memory to external storage, and thus ensuring availability of the logic memory area to the hypervisor.

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。

摘要： Controlled partition shut-down is provided within a shared memory partition data processing system including a shared memory partition, a paging service partition, a hypervisor and a shared memory pool within physical memory. The hypervisor manages access to logical pages within the pool and page-out of pages from the pool to external paging storage via the paging service partition. A respective paging service stream exists between the paging service partition and hypervisor for each shared memory partition, with each stream including a stream state. The control method includes: responsive to a shut-down initiating event, notifying the paging service partition to shut down, and determining whether a shared memory partition is currently active, and if so, signaling the hypervisor to complete paging activity for the active memory partition and waiting for its stream state to enter a suspended or a completed state before automatically shutting down the paging service partition.
