병렬 파일 시스템은 일반적으로 클러스터 시스템의 병렬 애플리케이션에서 과도한 파일 요청을 지원하는 데 사용되는 반면, 프리페칭은 파일 시스템 성능을 향상시키는 데 유용합니다. 본 논문에서는 VIA 기반 병렬 파일 시스템의 병렬 과학 응용 프로그램 및 멀티미디어 웹 서비스에 특히 적합한 테이블 비교 프리페칭 정책이라는 파일 액세스 패턴을 기반으로 하는 동적 파일 프리페칭 방식을 제안합니다. VIA는 TCP/IP와 같은 기존 통신 프로토콜의 통신 오버헤드를 완화합니다. 제안된 정책은 프리페치할 데이터를 예측하기 위해 테이블 비교 방법을 도입합니다. 또한 현재 사용 가능한 I/O 대역폭을 사용하여 프리페치를 수행할지 여부와 시기를 결정하는 알고리즘이 포함되어 있습니다. 실험 결과는 VIA 기반 병렬 파일 시스템에서 제안된 프리패치 정책을 사용하면 다양한 파일 액세스 패턴에 대해 더 높은 파일 시스템 성능을 제공한다는 것을 확인했습니다.

Abstract: A parallel file system is normally used to support excessive file requests from parallel applications in a cluster system, whereas prefetching is useful for improving the file system performance. This paper proposes dynamic file prefetching scheme based on file access patterns, named table-comparison prefetching policy, that is particularly suitable for parallel scientific applications and multimedia web services in a VIA-based parallel file system. VIA relieves the communication overhead of traditional communication protocols, such as TCP/IP. The proposed policy introduces a table-comparison method to predict data for prefetching. In addition, it includes an algorithm to determine whether and when prefetching is performed using the current available I/O bandwidth. Experimental results confirmed that the use of the proposed prefetching policy in a VIA-based parallel file system produced a higher file system performance for various file access patterns.
