    • An exemplary method implements load management for large granularity processes on application processors, APs. First data associated with the primary processes running on each AP is periodically collected, where the first data is proportional to processor occupancy, PO, for the primary processes running on each AP. Second data associated with auxiliary processes running on each AP is periodically collected where the auxiliary processes directly support the primary processes running on the respective AP. The second data is proportional to PO for the auxiliary processes running on each AP. A processor scaling factor and an overhead scaling factor are calculated for each AP based on the first and second data, respectively. The total amount of additional PO a second AP would incur to run a first large granularity process is determined by two aspects. The amount of additional PO due to the primary process is determined by applying at least the second processor scaling factor to a value related to an amount of primary process PO of the first process running on the first AP. The amount of additional PO due to overhead processes is determined by applying the overhead scaling factor of the second AP to the previously determined amount of additional PO due to the primary processes determined for the second AP.
    • 一种示例性方法对应用处理器,AP上的大粒度进程实施负载管理。 定期收集与每个AP上运行的主进程相关联的第一数据,其中第一数据与每个AP上运行的主进程的处理器占用率(PO)成比例。 定期收集与每个AP上运行的辅助进程相关联的第二数据,其中辅助进程直接支持在相应AP上运行的主进程。 第二个数据与每个AP上运行的辅助进程的PO成比例。 基于第一和第二数据分别为每个AP计算处理器缩放因子和开销缩放因子。 第二AP的额外PO的总量将用于运行第一大粒度过程由两个方面确定。 通过将至少第二处理器缩放因子应用于与在第一AP上运行的第一处理的主处理PO的量相关的值来确定由于主处理而引起的附加PO的量。 由于对于第二AP确定的主要处理,由开销处理引起的额外PO的量由第二AP的开销比例因子应用于先前确定的附加PO的量来确定。
