摘要： A method and system for controlling the allocation of a data processing system's resources among two or more components competing for the resources. An internal system value is modified to yield a modified system value. A utilization history is created by mapping a component's utilization of the system resources. Then, the priority of the component is calculated utilizing the utilization history and the modified system value within a priority calculation.

摘要： A method, system, and computer instructions for atomically updating 64-bit fields in the 32-bit AIX kernel, wherein the underlying hardware's 64-bit capable instructions are used to construct an atomic primitive. If a data request applies to the 32-bit kernel on 64-bit hardware execution environment, a load and reserve instruction sets a reservation for a memory location. The original 64-bit data object is decomposed into two 32-bit halves. A Shift Right Double Word Immediate (SRDI) instruction captures the high-order bits of the 64-bit register. If the store conditional instruction determines that the reservation is not lost, the store conditional instruction stores the result. If the store conditional instruction fails, the process returns to the reserve instruction until the store conditional operation returns a success.

摘要： A method, system and apparatus for integrating a system task scheduler with a workload manager are provided. The scheduler is used to assign default priorities to threads and to place the threads into run queues and the workload manager is used to implement policies set by a system administrator. One of the policies may be to have different classes of threads get different percentages of a system's CPU time. This policy can be reliably achieved if threads from a plurality of classes are spread as uniformly as possible among the run queues. To do so, the threads are organized in classes. Each class is associated with a priority as per a use-policy. This priority is used to modify the scheduling priority assigned to each thread in the class as well as to determine in which band or range of priority the threads fall. Then periodically, it is determined whether the number of threads in a band in a run queue exceeds the number of threads in the band in another run queue by more than a pre-determined number. If so, the system is deemed to be load-imbalanced. If not, the system is load-balanced by moving one thread in the band from the run queue with the greater number of threads to the run queue with the lower number of threads.
摘要翻译：提供了一种用于将系统任务调度器与工作负载管理器集成的方法，系统和装置。调度程序用于为线程分配默认优先级，并将线程置于运行队列中，工作负载管理器用于实现系统管理员设置的策略。其中一个策略可能是让不同类别的线程获得不同系统CPU时间的百分比。如果来自多个类的线程在运行队列中尽可能均匀地扩展，则可以可靠地实现该策略。为了这样做，线程被组织成类。每个类都根据使用政策与优先级相关联。该优先级用于修改分配给类中每个线程的调度优先级，并确定线程落在哪个频带或优先级范围。然后周期性地确定运行队列中的频带中的线程数是否超过另一运行队列中的频带中的线程数超过预定数量。如果是这样，系统被认为是负载不平衡的。如果没有，则系统通过将具有较大线程数的运行队列中的一个线程移动到具有较少线程数的运行队列来进行负载平衡。

摘要： An improved system and method for improving complex storage locks that manage access to a shared resource. A FIFO queue is maintained for processes waiting to read or write to the shared resource. When the shared resource is available, the first item is read from the queue. If the first item is a write requestor, the requestor is woken up in order to request the lock. If the first item on the queue is a read requestor, then that read requestor is woken up along with any other read requestors read from the queue until a write requestor is encountered or the end of the queue is reached. When the write wanted flag is set, new read requestors are denied access to the read lock, however any read requestors that were woken up in order to use the read lock are granted a read lock.

摘要： An apparatus and method for performing workload management is provided. In particular, an apparatus and method for performing workload management using class shares and tiers is provided. In the apparatus and method, each process is associated with a particular class of workload. Each class has an associated number of shares representing the importance of the class relative to other classes. Each class, in turn, is associated with a particular tier of workload importance. Classes of processes compete with other classes of processes in their same tier for system resources based on the number of shares that they have. These shares are representative of the percentage of the system resource the process is provided relative to the other classes in the same tier. Classes in one tier compete with classes in other tiers for system resources based on the priority assigned to the tiers.
