    • Architecture that facilitates the estimation of interference among workloads (e.g., virtual machines) due to sharing of a shared resource (e.g., a shared cache of a computer processor), and optimization of a desired performance objective such as power or energy use in the presence of the interference. Estimation is to the extent of interference by characterizing the nature of shared resource usage and its effect on performance. Performance optimization is accomplished using metrics based on the above estimation, or alternatively, an explicit measurement of the interference effects. Methods are employed to estimate interference on the workload's performance with changes in availability of the shared resource or with combinations of other workloads sharing the same resource and allocating workloads to one or more physical computers or resources to workloads such that a desired performance objective is optimized. The methods can include allocating workloads on demand.
    • 由于共享共享资源(例如,计算机处理器的共享缓存),有助于估计工作负载(例如,虚拟机)之间的干扰的架构,以及优化所期望的性能目标,例如存在的功率或能量使用 的干扰。 通过描述共享资源使用的性质及其对性能的影响来估计干扰程度。 使用基于上述估计的度量或者干扰效应的显式测量来实现性能优化。 使用方法来估计对共享资源的可用性的改变或者共享相同资源的其他工作负载的组合的工作负载的性能的干扰,并且将工作负载分配给一个或多个物理计算机或资源到工作负载,使得期望的性能目标被优化。 这些方法可以包括按需分配工作负载。

    • In a data center which includes a plurality of servers, a discovery computer, a power measurement system (PMS), and a plurality of power-circuits which supply power to the servers, the discovery computer performs the following actions for each server. It transmits a first command to the server causing the server to start generating a power consumption signature if the server is able to do so. Upon receiving a SUCCESS response from the server, it instructs the PMS to start measuring the power consumption from each power-circuit. After a prescribed interval of time has elapsed, it collects the measurements from the PMS and analyzes the measurements to look for the presence of the signature. Upon detecting the signature in the measurement taken from a particular power-circuit, the discovery computer concludes that the server is connected to the particular power-circuit and creates a mapping there-between.
    • 在包括多个服务器的数据中心中,发现计算机,功率测量系统(PMS)和向服务器供电的多个电源电路,发现计算机对每个服务器执行以下动作。 它向服务器发送第一个命令,使服务器能够开始生成功耗签名,如果服务器能够这样做。 当从服务器接收到SUCCESS响应时,它指示PMS开始测量每个电源电路的功耗。 在规定的时间间隔过去之后,它从PMS收集测量值并分析测量结果以查找签名的存在。 在从特定电源电路中检测到测量中的签名后,发现计算机断定服务器连接到特定的电源电路并在其间创建映射。
