Abstract:
1. An operations management apparatus for an information-processing system having a plurality of information-processing equipments, comprising: a first unit that obtains and stores a history of a time series variation in processing amounts of the information-processing equipments for each workload of the information-processing equipments by monitoring a first variable provided by the information-processing equipments; a second unit that calculates a summary statistic including a central tendency and a dispersion of the processing amounts for the respective workloads of the information-processing equipments based on the history; a third unit that preferentially allocates, in order, workloads to an information-processing equipment whose power efficiency is higher with respect to equipment performance among the information-processing equipments insofar as an expected value based on the summary statistic for workloads to be allocated to each information-processing equipment is within a threshold range preset for each information-processing equipment.
