摘要
It has been found that a more reasonable estimation of combined workloads can be achieved by enabling the ability to specify the confidence level in which to estimate the workload values. A method, computer readable medium and system are provided for estimating combined system workloads. The method comprises obtaining a set of quantile-based workload data pertaining to a plurality of systems and normalizing the quantile-based workload data to compensate for relative measures between data pertaining to different ones of the plurality of systems. A confidence interval may then be determined and the confidence interval used to determine a contention probability specifying a degree of predicted workload contention between the plurality of systems according to at least one probabilistic model. The contention probability may then be used to combine workloads for the plurality of systems and a result indicative of one or more combined workloads then provided.
