摘要： Distributing a thread for running on a physical processor and enabling the physical processor to be switched into a low power snooze state when said running thread is IDLE. However, this switching into said low power state is enabled to be delayed by a delay time from an IDLE dispatch from said running thread; such delay is determined by tracking the rate of the number of said IDLE dispatches per processor clock interval and dynamically varying said delay time wherein the delay time is decreased when said rate of IDLE dispatches increases and the delay time is increased when said rate of IDLE dispatches decreases.

摘要： A method manages memory paging operations. Responsive to a request to page out a memory page from a shared memory pool, the method identifies whether a physical space within one of a number of paging space devices has been allocated for the memory page. If physical space within the paging space device has not been allocated for the memory page, a page priority indicator for the memory page is identified. The memory page is then allocated to one of a number of memory pools within one of the number of paging space devices. The memory page is allocated one of the memory pools according to the page priority indicator of the memory page. The memory page is then written to the allocated memory pools.

摘要： Systems, methods and computer program products may provide managing utilization of one or more physical processors in a shared processor pool. A method of managing utilization of one or more physical processors in a shared processor pool may include determining a current amount of utilization of the one or more physical processors and generating an instruction message. The instruction message may be at least partially determined by the current amount of utilization. The method may further include sending the instruction message to a guest operating system, the guest operating system having a number of enabled virtual processors.

摘要： A virtual memory management unit can implement various techniques for managing paging space. The virtual memory management unit can monitor a number of unallocated large sized pages and can determine when the number of unallocated large sized pages drops below a page threshold. Unallocated contiguous smaller-sized pages can be aggregated to obtain unallocated larger-sized pages, which can then be allocated to processes as required to improve efficiency of disk I/O operations. Allocated smaller-sized pages can also be reorganized to obtain the unallocated contiguous smaller-sized pages that can then be aggregated to yield the larger-sized pages. If allocated smaller-sized pages belonging to a second process cannot be de-allocated by reorganizing, the second process can be terminated to de-allocate the pages. Furthermore, content can also be compressed before being written to the paging space to reduce the number of pages that are to be allocated to processes.

摘要： A method for graphically displaying central processing unit consumption for at least one variable capacity or uncapped partition including displaying CPU utilization or consumption of at least one variable capacity or uncapped partition in a variable-size colored pie chart. The pie chart shows time spent in at least one of user mode, operating system mode, I/O wait mode, or idle mode, with each mode being represented by a different color. An entitlement indicator is displayed for the effective minimum capacity of the at least one variable capacity or uncapped partition.

摘要： Management of a UNIX-style storage pools is enhanced by specially managing one or more memory management inodes associated with pinned and allocated pages of data storage by providing indirect access to the pinned and allocated pages by one or more user processes via a handle, while preventing direct access of the pinned and allocated pages by the user processes without use of the handles; scanning periodically hardware status bits in the inodes to determine which of the pinned and allocated pages have been recently accessed within a pre-determined period of time; requesting via a callback communication to each user process to determine which of the least-recently accessed pinned and allocated pages can be either deallocated or defragmented and compacted; and responsive to receiving one or more page indicators of pages unpinned by the user processes, compacting or deallocating one or more pages corresponding to the page indicators.

摘要： Automated techniques ensure that system central processing unit (“CPU”) power is not a bottleneck when migrating logical partitions from one system to another system or systems (e.g., in the event of a system evacuation). CPU resources needed to fully drive available bandwidth during the migration are computed. CPU resources of the system are then adjusted for the migration, which may comprise scaling down the CPU resources that are guaranteed for the executing partitions and/or adjusting relative partition variable weights to limit the amount of excess capacity that can be allocated to a partition.
