用于计算机系统的功率管理方法和系统
摘要：
本发明涉及一种用于计算机系统的功率管理方法和系统。各实施例包括一种用于管理计算机系统中的功率的方法，所述计算机系统包括主处理器以及包含已加电单元的有源存储器件，所述有源存储器件通过存储链路与所述主处理器通信，所述已加电单元包括处理元件。所述方法包括：所述主处理器处执行程序线程上的程序；遇到要由所述有源存储器件执行的第一代码段；基于所述主处理器遇到所述第一代码段，通过第一命令更改所述有源存储器件上的已加电单元的功率状态，所述第一命令包括存储命令。所述方法还包括：所述处理元件在第二时间执行所述第一代码段；基于所述处理元件执行所述第一代码段，将所述主处理器的功率状态从功率使用状态更改为功率节省状态。
摘要（英）：

Embodiments include a method for managing power in a computer system including a main processor and an active memory device including powered units, the active memory device in communication with the main processor by a memory link, the powered units including a processing element. The method includes the main processor executing a program on a program thread, encountering a first section of code to be executed by the active memory device, changing, by a first command, a power state of a powered unit on the active memory device based on the main processor encountering the first section of code, the first command including a store command. The method also includes the processing element executing the first section of code at a second time, changing a power state of the main processor from a power use state to a power saving state based on the processing element executing the first section.
