Abstract: A method and an apparatus to dynamically distribute privileges among a plurality of processes are described. Each process may have attributes including a privilege to control access to processing resources. A first process may be running with a first privilege prohibited from access to a processing resource. A second process may be running with a second privilege allowed to access the processing resource. The first process may receive a request from the second process to perform a data processing task for the second process. In response, the second privilege may be dynamically transferred to the first process to allow the first process to access the processing resource. The first process may perform operations for the data processing task with the second privilege transferred from the second process.

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。

Abstract translation: 描述了在多个处理之间动态分配特权的方法和装置。 每个进程可以具有包括控制对处理资源的访问的特权的属性。 第一进程可以以禁止访问处理资源的第一权限运行。 第二个进程可能正在运行，允许访问处理资源的第二个权限。 第一进程可以从第二进程接收对第二进程执行数据处理任务的请求。 作为响应，第二权限可以被动态地转移到第一进程以允许第一进程访问处理资源。 第一进程可以执行具有从第二进程传送的第二特权的数据处理任务的操作。

Abstract: Systems and methods are disclosed for logging encoded diagnostic information from a sequence of processing operations, the processing operations generated by an activity in a computing environment. Diagnostic information is tracked by activity, across process boundaries where the processes can be in computationally isolated, or “sandboxed”. Within each process, diagnostic information for an activity is stored in an activity-specific buffer registered with a kernel in the computing environment. For each activity in the computing system, the kernel keeps a list of all processes that have performed, or are performing, a processing task of the activity. The kernel also keeps a reference to the activity-specific log buffers for the activity for each process associated with the activity. If a processing operation for an activity fails, all activity-specific logs from all processes that are associated with the activity can be collected. A report can be generated from the collected logs for the activity.

Abstract: A method and an apparatus for priority donations among different processes are described. A first process running with a first priority may receive a request from a second process running with a second priority to perform a data processing task for the second process. A dependency relationship may be identified between the first process and a third process running with a third priority performing separate data processing task. The dependency relationship may indicate that the data processing task is to be performed via the first process subsequent to completion of the separate data processing task via the third process. The third process may be updated with the second priority to complete the separate data processing task. The first process may perform the data processing task with the second priority for the second process.
