Sistem fail selari biasanya digunakan untuk menyokong permintaan fail yang berlebihan daripada aplikasi selari dalam sistem kluster, manakala prefetching berguna untuk meningkatkan prestasi sistem fail. Kertas kerja ini mencadangkan skim prafetch fail dinamik berdasarkan corak capaian fail, dinamakan dasar prafetch perbandingan jadual, yang amat sesuai untuk aplikasi saintifik selari dan perkhidmatan web multimedia dalam sistem fail selari berasaskan VIA. VIA melegakan overhed komunikasi protokol komunikasi tradisional, seperti TCP/IP. Dasar yang dicadangkan memperkenalkan kaedah perbandingan jadual untuk meramalkan data untuk pra-pengambilan. Di samping itu, ia termasuk algoritma untuk menentukan sama ada dan bila prapengambilan dilakukan menggunakan lebar jalur I/O semasa yang tersedia. Keputusan eksperimen mengesahkan bahawa penggunaan dasar prafetch yang dicadangkan dalam sistem fail selari berasaskan VIA menghasilkan prestasi sistem fail yang lebih tinggi untuk pelbagai corak capaian fail.

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.
