Abstract

Process creation and disappearance is a large load among processing of operating system. The research that speeds up process creation since before, is being done and sticky bit and vfork system call in the UNIX are materialized. For example, process creation and disappearance break out a repetition, because compiler is run many times in UNIX command of "make". Because of this, it is important when it speeds up the processing of operating system, to speed up process creation and disappearance. We perceive to the processing that delete a process and create the same process newly. And we propose mechanism of restarting a process by initializing data segments. The mechanism is able to run the process that ran it once from the beginning once again. This paper describes mechanism of restarting process by initializing data segments and reports performance of the mechanism, comparison with established operating system and evaluation by a real application.
