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： A mechanism is provided for temporarily allocating dedicated processors to a shared processor pool. A virtual machine monitor determines whether a temporary allocation associated with an identified dedicated processor is long-term or short-term. Responsive to the temporary allocation being long-term, the virtual machine monitor determines whether an operating frequency of the identified dedicated processor is within a predetermined threshold of an operating frequency of one or more operating systems utilizing the shared processor pool. Responsive to the operating frequency of the identified dedicated processor failing to be within the predetermined threshold, the virtual machine monitor either increases or decreases the frequency of the identified dedicated processor to be within the predetermined threshold of the operating frequency of the one or more operating systems utilizing the shared processor pool and temporarily allocates the identified dedicated processor to the shared processor pool.

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： 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： 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： 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： An apparatus, program product and method for tracking the state of a migrating logical partition. Embodiments may use the state to determine the readiness and/or appropriateness of a page of the logical partition for transferring. The state may include a value or other data used to track changes affecting the page or the relative ease and/or appropriateness of migrating the page. A page manager table with entries corresponding to the state of each page of the logical partition may be used to track the state while the logical partition continues to run during a migration.
