摘要： A partition manager for managing logical partitions in a computer system includes hooks to low-level operating system code in one of the logical partitions. By using the operating system code to manage the resources of a computer system, any changes that are made to the operating system are automatically reflected in the function of the partition manager. In addition, low-level functions of operating systems, which are often well-debugged and tested, can be used when generating a new partition manager, greatly simplifying the time and reducing the cost of producing a partition manager.

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： 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。

摘要： Maintaining data integrity for a logical partition by enabling nonintrusive switching of page tables used during a migration of the logical partition from a source computer system to a target computer system. A first page table stores a plurality of page entries made within a logically partitioned environment. A second page table stores one or more page entries generated during the migration. After migration, the processor page table pointer is switched to point to the first page table. A page entry in the second page table corresponding to a page entry made to the first page table by the logical partition may be invalidated in response to a page table hypervisor call made by the logical partition. In parallel, a plurality of entries generated during the migration of the logical partition in the second page table may be read through and invalidated.

摘要： An apparatus, program product and method maintains data integrity for a logical partition by enabling nonintrusive switching of page tables used during a migration of the logical partition from a source computer system to a target computer system. A first page table may be configured to store a plurality of page entries made within a logically partitioned environment. A second page table may be used during migration to store one or more page entries generated during the migration. After migration, the processor page table pointer may be transparently switched to point to the first page table. A page entry in the second page table corresponding to a page entry made to the first page table by the logical partition may be invalidated in response to a page table hypervisor call made by the logical partition. In parallel, a plurality of entries generated during the migration of the logical partition in the second page table may be read through and invalidated. This reading through of the entries may be accomplished concurrently with the invalidation of the corresponding page entry in the second page table in response to a page table call made by the logical partition. Moreover, the reading of the entries may be accomplished in intervals and with portions of the plurality of entries.
