초록

POFS는 SPAX 컴퓨터에서 운용될 병렬 파일 시스템이다. SPAX는 ETRI에서 개발중인 클러스터 SMP 구조를 가지는 다중 프로세서 컴퓨터이며 SPAX의 운영체제는 Chorus 마이크로커널에 기반한 MISIX이다. 마이크로커널 기반의 운영체제는 마이크로커널의 IPC를 기반으로 구현된 서버의 집합이며, 운영체제의 서브시스템들 혹은 서브시스템들과 사용자 프로그램은 클라이언트/서버 구조를 가지게 된다. 그러므로, 운영체제의 서브시스템을 위한 통신 모듈의 설계 방법은 시스템의 성능에 직접적인 영향을 준다. 본 논문은 MISIX의 병렬 파일 시스템인 POFS 개발함에 있어서 제기된 통신 모듈의 구조와 성능에 관해 기술한다. POFS는 높은 병렬성 및 확장성을 가지며, 단일 시스템 이미지를 제공하는 분산 환경의 파일 시스템이다. POFS의 통신 모듈은 클라이언트/서버 구조인 POFS의 특성을 효과적으로 지원한다.

This paper is concerned with development of a communication module of POFS(Parallel Operating File System), which is the parallel file system to be operated on SPAX computer. SPAX is multiprocessor computer with clustering SMP architecture and being developed by ETRI. The operating system for SPAX is MISIX based on the Chorus microkernel. POFS has client/server architecture basically so that it is important to design a communication module. The communication module is so easily affected by network environment that bad design is the major reason that decreases the portability and performance of the parallel file system. This paper describes the structure and performance of the communication of the POFS. the theme is issued in the course of designing and developing POFS. The communication module of POFS was designed to support the portability and the architecture of parallel file system.
