We consider single-pass, lossless, queueing systems at steady-state subject to Poisson job arrivals at an unknown rate. Service rates are allowed to depend on the number of jobs in the system, up to a fixed maximum, and power consumption is an increasing function of speed. The goal is to control the state dependent service rates such that both energy(More)
—Efficient management of supercomputing facilities requires estimates of future workload based on past user behaviour. For supercomputers with large numbers of users, aggregate user behaviour is commonly assumed to be best in prediction of future workloads, however for systems with smaller numbers of users the question arises as to whether it is still(More)
