摘要： A method of executing a loop over an integer index range of indices in a parallel manner includes assigning a plurality of index subsets of the integer index range to a corresponding plurality of threads, and defining for each index subset a start point of the index subset, an end point of the index subset, and a boundary point of the index subset positioned between the start point and the end point of the index subset. A portion of the index subset between the start point and the boundary point represents a private range and the portion of the index subset between the boundary point and the end point represents a public range. Loop code is executed by each thread based on the index subset of the integer index range assigned to the thread.
摘要翻译：以并行方式在索引的整数索引范围上执行循环的方法包括将整数索引范围的多个索引子集分配给相应的多个线程，并为每个索引子集定义索引子集的起始点，索引子集的终点，以及位于索引子集起始点和终点之间的索引子集的边界点。起始点和边界点之间的索引子集的一部分表示专用范围，边界点和终点之间的索引子集的一部分表示公共范围。循环代码由每个线程基于分配给线程的整数索引范围的索引子集执行。

摘要： A runtime environment allows a scheduler in a process of a computer system to be finalized prior to the process completing. The runtime environment causes execution contexts that are inducted into the scheduler and execution contexts created by the scheduler to be tracked. The runtime environment finalizes the scheduler subsequent to each inducted execution context exiting the scheduler and each created execution context being retired by the scheduler.

摘要： A scheduler in a process of a computer system allows an external execution context to execute on a processing resource allocated to the scheduler. The scheduler provides control of the processing resource to the external execution context. The scheduler registers for a notification of an exit event associated with the external execution context. In response to receiving the notification that the exit event has occurred, the scheduler regains control of the processing resource and causes a task associated with an execution context controlled by the scheduler to be executed by the processing resource.
摘要翻译：计算机系统进程中的调度器允许外部执行上下文在分配给调度器的处理资源上执行。调度器提供对外部执行上下文的处理资源的控制。调度器注册与外部执行上下文相关联的退出事件的通知。响应于接收到退出事件已经发生的通知，调度器重新获得对处理资源的控制，并且导致由调度器控制的执行上下文相关联的任务由处理资源执行。

摘要： A resource manager manages processing and other resources of schedulers of one or more processes executing on one or more computer systems. For each scheduler, the resource manager determines an initial allocation of resources based on the policy of the scheduler, the availability of resources, and the policies of other schedulers. The resource manager receives feedback from the schedulers and dynamically changes the allocation of resources of schedulers based on the feedback. The resource manager determines if changes improved the performance of schedulers and commits or rolls back the changes based on the determination.

摘要： A memory allocator is provided for each processor resource in a process of a computer system. Each memory allocator includes a set of pages, a locally freed list of objects, and a remotely freed list of objects. Each memory allocator requests the pages from an operating system and allocates objects to all execution contexts executing on a corresponding processing resource. Each memory allocator attempts to allocate an object from the locally freed list before allocating an object from the remotely freed list or an allocated page.

摘要： Computer systems attempt to manage resource pools of a dynamic number of similar resources and work tasks in order to optimize system performance. Work requests are received into the resource pool having a dynamic number of resources instances. An instance-throughput curve is determined that relates a number of resource instances in the resource pool to throughput of the work requests. A slope of a point on the instance-throughput curve is estimated with stochastic gradient approximation. The number of resource instances for the resource pool is selected when the estimated slope of the instance-throughput curve is zero.
