Experiments with the Burroughs B 3500 Computer System Using a Synthetic Workload
Abstract
An application of synthetic workloads in the evaluation of the performance of batch processing, multiprogrammed, real-memory computer systems is described. Results of controlled experiments with a Burroughs B 3500 computer system in a dedicated environment using a test workload are presented. The test workload is constructed by matching the joint probability distribution of the selected real workload characteristics. They are the core size of the program, the number of files, I/0 activity to disk and the CPU time. These characteristics are determined from the system accounting package, LOGGER. The accounting data, collected by LOGGER during the controlled experiments with the synthetic workload, are used to determine the utilization of the processor and the I/0 channel. These utilization values compare favorably with those measured by a DYNAPROBE 7900 hardware monitor.
