Method and system for calculating power loss index

The invention discloses a method for calculating a power loss index during operation of an information processing system. The method comprises the steps of obtaining utilization rate values for one ormore components in the information processing system; multiplying the utilization rate values for the one or more components by load factors of the one or more components to calculate individual power loss of each of the one or more components; and summating the individual power losses of the one or more components to calculate the power loss index of the information processing system. The invention furthermore discloses an apparatus for calculating the power loss index during the operation of the information processing system. 公开了种在信息处理系统的操作期间计算功率损耗指数的方法，包括以下步骤：获得针对信息处理系统中的个或多个组件的利用率值；将针对个或多个组件的利用率值分别与个或多个组件的负载因子相乘，以计算个或多个组件中的每个的个体功率损耗；以及对个或多个组件的个体功率损耗求和，以计算信息处理系统的功率损耗指数。还公开了种用于在信息处理系统的操作期间计算功率损耗指数的装置。
