摘要： A resource and partition manager of the preferred embodiments includes a lock mechanism that operates on a plurality of locks that control access to individual I/O slots. The resource and partition manager uses the lock mechanism to obtain a lock on an I/O slot when transferring control of the I/O slot to a logical partition that is powering on and when removing the I/O slot from a logical partition that is powering off. The resource and partition manager uses the lock mechanism to remove control of an I/O slot from, or return control to, an operating logical partition in order to facilitate hardware service operations on that I/O slot or on the physical enclosure in which it is contained.

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： 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 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 method utilizes a multithreaded processor having at least one hardware thread among a plurality of hardware threads that is capable of being selectively activated and deactivated responsive to a control circuit.

摘要： A partition migration mechanism migrates a logical partition executing an operating system and resumes the logical partition before all resources in the logical partition have been migrated. When a partition is being migrated, a call checkpoint mechanism creates checkpoints of the state of the operating system when the partition manager is called. Before performing the call to the partition manager, a check is made to determine if all resources required by the call are available. If so, the partition manager call is executed. If all resources required by the call are not available, a resource fault is indicated, which causes the operating system state from the last checkpoint to be restored and a corresponding virtual CPU to be preempted until the resource that caused the fault becomes available. Exceptions that do not require the missing resource may be performed while the virtual CPU awaits the resource to become available.
摘要翻译：在迁移逻辑分区中的所有资源之前，分区迁移机制将迁移执行操作系统的逻辑分区并恢复逻辑分区。当分区正在迁移时，调用检查点机制会在调用分区管理器时创建操作系统状态的检查点。在执行对分区管理器的呼叫之前，进行检查以确定呼叫所需的所有资源是否可用。如果是这样，则执行分区管理器调用。如果呼叫所需的所有资源都不可用，则会指示资源故障，从而导致最后一个检查点的操作系统状态恢复，相应的虚拟CPU将被抢占，直到导致故障的资源变为可用。可以在虚拟CPU等待资源变为可用时执行不需要缺少资源的异常。

摘要： An apparatus, program product and method track concurrent uses of a computer program across a plurality of logical partitions in a logically partitioned computer, such that a decision as to whether to grant or deny a request to use the computer program in a particular logical partition may be made based upon whether the requested use, coupled with other uses in other logical partitions in the computer, would violate a concurrent use software license associated with the computer program. As such, the license restrictions of a concurrent use software license can be enforced on a logically partitioned computer regardless of the particular logical partitions within which a computer program executes.

摘要： A method of handling conflicts between threads, including an initiating thread and at least one other thread, for at least one shared resource in a multi-threaded processing system having a processor and memory includes setting a location in memory for each other thread on the processor with the initiating thread. The initiating thread signals an inter-processor interrupt (IPI) to all other threads on the processor. For each other thread, an interrupt handler is initiated where each other thread: acknowledges receipt of the interrupt, and proceeds to spin on the respective location in memory that was set, thereby guaranteeing that the respective other thread will not be using any shared resource of the processor. The initiating thread waits for other threads on processor to acknowledge the inter-processor interrupt (IPI), and when all the other threads have acknowledged the inter-processor interrupt (IPI), the initiating thread proceeds to save the state of the shared resource in memory, sets the shared resource to the state wanted, uses the shared resource, and restores the original state of the resource. The initiating thread then releases the other threads from their spin by resetting the location in memory that was set above. All the threads then proceed with their computations.
摘要翻译：一种在具有处理器和存储器的多线程处理系统中处理针对至少一个共享资源的线程之间的冲突的方法，包括发起线程和至少一个其他线程，包括为处理器中的每个其他线程设置存储器中的位置与启动线程。启动线程向处理器上的所有其他线程发出处理器间中断（IPI）信号。对于每个其他线程，启动中断处理程序，其中每个其他线程：确认中断的接收，并且继续旋转在设置的存储器中的相应位置，从而保证相应的其他线程将不使用任何共享资源处理器。启动线程等待处理器上的其他线程确认处理器间中断（IPI），并且当所有其他线程都确认了处理器间中断（IPI）时，启动线程继续保存共享资源的状态内存，将共享资源设置为所需状态，使用共享资源，并恢复资源的原始状态。然后，启动线程通过重置上面设置的内存中的位置来释放其他线程。所有线程然后继续进行计算。
