Exemplary methods, systems, and products are described for executing an overall quantity of data processing within an overall processing period that include executing repeatedly through a series of iterations a portion of the overall quantity of data processing that can be completed in a set processing period, wherein each iteration includes the set processing period and a variable delay period and calculating the variable delay period for an iteration in dependence upon the set processing period, a portion of the overall quantity of data processing performed during the set processing period of the iteration, the overall quantity of data processing, and the overall processing period.
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:
In response to a hypervisor page fault for memory that is not resident in a shared memory pool, an I/O paging request is sent to an external storage paging space. In response to a paging service partition encountering an I/O paging error, a paging failure indication is sent to the hypervisor. A simulated machine check interrupt instruction is sent from the hypervisor to the shared memory partition and a machine check handler obtains control. The machine check handler performs data analysis utilizing an error log in an attempt to isolate the I/O paging error to a process or a set of processes in the shared memory partition. The process or set of processes associated with the I/O paging error, or the shared memory partition itself, may be terminated. Finally, the shared memory partition may clear or initialize the page associated with the I/O paging error.

Assigning a processor to a logical partition in a computer supporting multiple logical partitions that include assigning priorities to partitions, detecting a checkstop of a failing processor of a partition, retrieving the failing processor's state, replacing by a hypervisor the failing processor with a replacement processor from a partition having a priority lower than the priority of the partition of the failing processor, and assigning the retrieved state of the failing processor as the state of the replacement processor.
