Many services can be provided on a computer by improvement of computer performance. Also, each service requests different processing performance. Besides, one service is composed of many processes in many cases. Thus these processes need to be a unit for process scheduling. We proposed a mechanism of regulating execution performance for multi process by execution resource. In this paper, we report a result of an evaluation of our proposed mechanism by using Web server. We describe BSD/OS compatible system-call interface, and a result using the interface and Apache Web server. Also, we show that our proposed mechanism is able to regulate execution performance of multi process.

The various services, which use a computer, are provided. There are many cases the service, which is provided with a computer, is composed of multi procrsses. For example, in Web server, a child process processes a request from a client. We proposed speed control mechanism of program execution. The mechanism is able to regulate the execution speed of one process. However, execution speed of a service, which is composed of the multi processes, is unable to be regulated. Therefore, we propose the execution speed control mechanism of process group by using"execution"resource. This paper describes overview of Tender operating system, speed control mechanism of program execution and the guarantee mechanism of service processing time. Furthermore, it proposes execution speed control mechanism of process group by execution on Tender.

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.

Evaluation of Multi Processes Control Mechanism for Regulating Program Execution Speed

TABATA Toshihiro, TANIGUCHI Hideo

IPSJ SIG Notes 84 ( 43 ) 229 - 236 2000.5

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

Computer user control speed of software running by using our mechanism of regulating program execution speed. We described mechanism for regulating process execution speed based by our suggested process schedule. But the mechanism targeted controlling one process. Therefore uniformity of processing is lower when we regulate multi processes execution speed. In this paper, we suggest the mechanism for controlling multi processes. And we report relation about uniformity of processing between evaluation of simulator and experimentation.

We describe inter process communication on Tender operating system. Heterogeneous Virtual Storage(HVS) of Tender is integrated both single virtual storage and multiplc virtual storage. HVS has multiple virtual spaces. And there are over zero processes on a virtual space. And a process can migrate between virtual spaces. So that, processes can cooperat with other processes in processing. We create new resources"container","container box" and "event" to realize efficient inter process communication. This paper describes mechanism of inter process communication and shows evaluation of inter process communication.

We suggest function of Heterogeneous Virtual Storage(HVS) that is fused both single virtual storage and multiple virtual storage. HVS has multiple virtual storage spaces. And there are over zero processes on a space. And a process can migrate between virtual storage spaces. Therefore, HVS has both single virtual storage's advantages and multiple virtual storage's advantages. We implemented and evaluated HVS on Tender operating system. To use existed virtual storage space reduce the time of creating process and deleting process. And the time of process migration is not influence from the size of process, and is about 0.7 millisecond.
