The Way to Produce the Quasi-workload in a Cluster

摘要

Resource Management Systems (RMS) can be used to improve the utilization of a cluster of workstations or processors. In a system which has a mixture of interactive and batch work and a mixture of serial and parallel jobs there is no single measure which determines the effective utilization of the cluster. We propose a mathematically well-defined procedure for determining an ensemble of states "sufficiently close" to the measured workload of the cluster. We call these states quasi-workloads and suggest how they can provide a basis for simulations which predict the changes in cluster performance for differing RMS policies and schedules.
