Abstract: A method and apparatus of a device for performance management by terminating application programs that consume an excessive amount of system resources is described. The device receives a resource consumption threshold and a detection period. The device further monitors a resource usage of an application program. The device determines whether the resource usage of the application program exceeds the resource consumption threshold for the detection period. The device further terminates the application program when the resource usage exceeds the resource consumption threshold for the detection period.

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 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。
