摘要： A method for a framework for scheduling tasks in a multi-core processor or multiprocessor system is provided in the illustrative embodiments. A thread is selected according to an order in a scheduling discipline, the thread being a thread of an application executing in the data processing system, the thread forming the leader thread in a bundle of threads. A value of a core attribute in a set of core attributes is determined according to a corresponding thread attribute in a set of thread attributes associated with the leader thread. A determination is made whether a second thread can be added to the bundle such that the bundle including the second thread will satisfy a policy. If the determining is affirmative, the second thread is added to the bundle. The bundle is scheduled for execution using a core of the multi-core processor.

摘要： A method for dynamic power and performance calibration of a data processing system is provided in the illustrative embodiments. A synthesized program loaded in the data processing system is executed responsive to detecting an event in the data processing system. The synthesized program is configured to generate a set of data that is indicative of the data processing system's power-performance characteristics under varying conditions of operation. Using the set of data, a determination is made of a performance limit on an operation of the data processing system under present operating conditions of the data processing system. A parameter of the data processing system is calibrated to operate the data processing system within the performance limit.

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 method of managing power in a data processing system includes monitoring a system parameter indicative of power consumption. Responsive to determining that the parameter differs from a specified threshold, a system guest, such as an operating system, is forced to release a portion of its allocated system memory. The portion of system memory released by the guest is then reclaimed by the system. The reclaimed system memory and the resulting decrease in allocated memory may enable the system to reduce system memory power consumption. The operating system may de-allocate a portion of system memory when a balloon code device driver executing under the operating system requests the operating system to allocate memory to it. The system memory allocated to the balloon device driver is then reclaimed by supervisory code such as a hypervisor.

摘要： A system, apparatus and method for transmitting data on a private network in blocks of data without using TCP/IP as a protocol are provided. When data is to be transmitted on a private network, the data is divided into a plurality of packets and a MAC header is added to each packet. The header contains hardware addresses of the transmitting and receiving hosts as well as parameters of the data being transmitted. The hardware addresses are used to route the packets through the private network therefore obviating the use of TCP/IP to perform the same task. The data is ordinarily stored in contiguous sectors of a storage device; thus, ensuring that almost every packet will either contain data from a block of sectors or is a receipt acknowledgement of such packet.
摘要翻译：提供了一种用于在不使用TCP / IP作为协议的情况下以数据块的方式在专用网上发送数据的系统，装置和方法。当要在专用网络上传输数据时，数据被分成多个分组，并且将MAC报头添加到每个分组。报头包含发送和接收主机的硬件地址以及要发送的数据的参数。硬件地址用于通过专用网络路由数据包，从而避免使用TCP / IP执行相同的任务。数据通常存储在存储设备的连续扇区中; 因此，确保几乎每个分组将包含来自扇区块的数据或者是这样的分组的接收确认。

摘要： A processing system and computer program provides memory power management and memory failure management in large scale systems. Upon a decision to take a memory module off-line or place the module in an increased-latency state for power management, or upon a notification that a memory module has failed or been taken off-line or has had latency increased by another power management control mechanism, a hypervisor that supports multiple virtual machines checks the use of pages by each virtual machine and its guest operating system by using a reverse mapping. The hypervisor determines which virtual machines are using a particular machine memory page and may re-map the machine memory page to another available machine page, or may notify the virtual machines that the memory page has become or is becoming unavailable via a fault or other notification mechanism. Alternatively, or in the absence of a response from a virtual machine, the hypervisor can shut down the affected partition(s).
