Abstract: A method and apparatus using temperature margin to balance performance with power allocation. Nominal, middle and high power levels are determined for compute elements. A set of temperature thresholds are determined that drive the power allocation of the compute elements towards a balanced temperature profile. For a given workload, temperature differentials are determined for each of the compute elements relative the other compute elements, where the temperature differentials correspond to workload utilization of the compute element. If temperature overhead is available, and a compute element is below a temperature threshold, then particular compute elements are allocated power to match or drive toward the balanced temperature profile.
Abstract translation: 使用温度裕度平衡性能与功率分配的方法和装置。 对于计算元素确定标称，中等和高功率电平。 确定一组温度阈值，其将计算元件的功率分配驱动到平衡温度分布。 对于给定的工作负载，相对于其他计算元件，每个计算元素确定温差，其中温差对应于计算元件的工作负载利用率。 如果温度开销可用，并且计算元件低于温度阈值，则特定计算元件被分配功率以匹配或驱动平衡温度曲线。
