Abstract: A technique of operating a data processing system, includes logging addresses for cache lines modified by a producer core in a data array of a producer cache to create a high-availability (HA) log for the producer core. The technique also includes moving the HA log directly from the producer cache to a consumer cache of a consumer core and moving HA data associated with the addresses of the HA log directly from the producer cache to the consumer cache. The HA log corresponds to a cache line that includes multiple of the addresses. Finally, the technique includes processing, by the consumer core, the HA log and the HA data for the data processing system.

Abstract: In a NUMA-topology computer system that includes multiple nodes and multiple logical partitions, some of which may be dedicated and others of which are shared, NUMA optimizations are enabled in shared logical partitions. This is done by specifying a home node parameter in each virtual processor assigned to a logical partition. When a task is created by an operating system in a shared logical partition, a home node is assigned to the task, and the operating system attempts to assign the task to a virtual processor that has a home node that matches the home node for the task. The partition manager then attempts to assign virtual processors to their corresponding home nodes. If this can be done, NUMA optimizations may be performed without the risk of reducing the performance of the shared logical partition.

Abstract translation: 在包含多个节点和多个逻辑分区的NUMA拓扑计算机系统中，其中一些可能是专用的，其他的可以是共享的，而在共享逻辑分区中启用了NUMA优化。 这是通过在分配给逻辑分区的每个虚拟处理器中指定家庭节点参数来完成的。 当由共享逻辑分区中的操作系统创建任务时，将家庭节点分配给该任务，并且操作系统尝试将该任务分配给具有与该任务的家庭节点匹配的家庭节点的虚拟处理器 。 然后，分区管理器尝试将虚拟处理器分配给其对应的家庭节点。 如果可以这样做，可以执行NUMA优化，而不会降低共享逻辑分区的性能。
