Abstract: A method and an apparatus for activity based execution scheduling are described. Activities may be tracked among a plurality of threads belonging to a plurality of processes running in one or more processors. Each thread may be associated with one of the activities. Each activity may be associated with one or more of the threads in one or more of the processes for a data processing task. The activities may be ordered by a priority order. A group of the threads may be identified to be associated with a particular one of the activities with highest priority based on the priority order. A thread may be selected from the identified threads for next scheduled execution in the processors.

Abstract translation: 描述了一种用于基于活动的执行调度的方法和装置。 可以在属于在一个或多个处理器中运行的多个进程的多个线程中跟踪活动。 每个线程可能与其中一个活动相关联。 每个活动可以与用于数据处理任务的一个或多个处理中的一个或多个线程相关联。 活动可按优先顺序排序。 一组线程可以被识别为基于优先级顺序与具有最高优先级的特定活动相关联。 可以从所识别的线程中选择线程以用于处理器中的下一个预定执行。
