Conversationally interactive computer systems display throughput which varies in accordance with fluctuations in load. Experiments have been made on a means of dynamically controlling the load for this type of system to automatically keep throughput at a high level.
A program called the "Load Leveler" has been built into the M44/44X operating system to set the instantaneous level of multiprogramming in order to improve system throughput. The factors involved are described and results of the Load Leveling operation are presented. Results are encouraging since system performance is improved with use of the Load Leveler. The improved performance is believed due to a relexation of contention for page space during squeezed core conditions,
Comparison of system performance with and without the load leveler is made.
