Implementation and evaluation of multiple processes control mechanism for regulating program execution speed

Abstract

If it is possible to regulate program execution speed, we can control the execution speed arbitrarily, regardless of hardware performance, in order to improve the convenience of service. H. Taniguchi (2000) has previously proposed a mechanism to regulate the program execution speed. The proposed mechanism can control only one process, but it can't control multiple processes. However, since in most cases one service consists of multiple processes, it is necessary to establish a multi-process control mechanism for regulating the program execution speed. There are numerous combinations of processes when multiple processes are controlled. Therefore the execution speeds of all the processes need to be regulated smoothly in all combinations. We show a basic mechanism for regulating the program execution speed and describe the problem and treatment for a multi-process control mechanism. This paper reports the result of our evaluation.
