    摘要： A method, system, and computer usable program product for power distribution considering cooling nodes in a data processing environment. A power demand of a data processing environment is determined for a period. The data processing environment includes a set of computing nodes and cooling nodes. A determination is made that the power demand will exceed a limit on electrical power available to the data processing environment for the period if the computing nodes and the cooling nodes in the data processing environment are operated in a first configuration. A first amount of power is redistributed from a cooling node in the data processing environment to a computing node in the data processing environment such that a temperature related performance threshold of a subset of computing nodes is at least met.

    摘要： A partition that is executed by multiple processing nodes. Each node includes multiple cores and each of the cores has a frequency that can be set. A first frequency range is provided to the cores. Each core, when executing the identified partition, sets its frequency within the first frequency range. Frequency metrics are gathered from the cores running the partition by the nodes. The gathered frequency metrics are received and analyzed by a hypervisor that determines a second frequency range to use for the partition, with the second frequency range being different from the first frequency range. The second frequency range is provided to the cores at the nodes executing the identified partition. When the cores execute the identified partition, they use a frequencies within the second frequency range.

    摘要： A power-aware, logically partitioned data processing system and corresponding method of use include a set of physical resources and a hypervisor. The hypervisor creates partitions and allocates at least some of the physical resources to the partitions. The system further includes means for reducing the power consumption of any physical resources not allocated to a partition. The hypervisor may allocate physical resources to the partitions to maximize the number of unallocated physical resources. The physical resources may include processors and the hypervisor may allocate a fractional portion of at least one processor to a partition. In this embodiment, the system may reduce power consumption by scaling the supply voltage or clocking frequency to the fractionally allocated processor. The resources may include memory modules and the hypervisor may dynamically reduce the allocated memory and power consumption by minimizing the number of memory modules needed to support the memory allocated to the partitions. The resources may also include disks provided through a storage-area network (SAN). This SAN may be partitioned in the same manner as the main data processing system, and the SAN partitioning may turn off power to unallocated or unused disk drives to reduce power consumption.

    摘要： A data processing network, server device, and method in which an application program memory usage parameter is monitored where the parameter is indicative of the server device's performance and loading. If the memory usage parameter exceeds a specified criteria, the amount of the system memory available to the application program is reduced and a physical section of memory is deactivated to save power. The parameter may represent the server application's file cache hit rate and reducing the amount of memory available to the application program may include reducing the file cache size. Reducing the file cache size may include invalidating file cache data based upon a purge criteria that indicates when the data was most recently accessed. If the memory usage parameter falls below the specified criteria, additional system memory made be activated and made available to the application program to maintain performance at a desired level.

    摘要： A system and method for synchronizing a set of nodes connected to a central switch in a multi-node data processing system, such as a NUMA data processing system, are disclosed. Initially, time base register values are retrieved from each of the set of nodes. A common time base register value is then determined based upon the time base register values received from the nodes. The common time base register value that is determined is then broadcast to each of the nodes. Prior to reading the time base register values, packet traffic among the set of nodes may be halted by broadcasting a halt traffic packet to each of the nodes. In this embodiment, normal packet traffic may be resumed after synchronization by broadcasting a resume traffic packet to each of the nodes. The time base register values may be read by issuing a special purpose interrupt from a node adapter to one of the node processors in response to the adapter receiving a read time base packet from the switch. The common time base register value may be determined by selecting the maximum of the time base register values read from each of the set of nodes and adjusting the maximum time base register value by an adjustment factor, such as the time required for a packet to travel from the central switch to a node processor plus the time required for a packet to travel from a node processor to the central switch. The synchronization process may be repeated periodically such as by initiating a synchronization each time a decrementing register of the central switch reaches zero.
