Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] The essence of the Simple Grid File System (SGFS) of the present invention is to abstract the files and related information involved in the grid computing environment, and provide a way to access grid files in the global namespace by redefining them. Methods. Therefore, we first explain the relevant definitions of the file system. Before the definition, explain the related concepts involved.

[0040] Host user: In a multi-user multi-task time-sharing operating system, a user who is allowed to legally use host system resources by logging in.

[0041] Grid user: A user who logs into a grid system and can legally use grid resources.

[0042] Host Files: Files managed by the host file system.

[0043] Metadata service: Provides services for managing the metadata of the full grid file system.

[0044] In the above definition, a host user...

Abstract

The invention provides a method used to process files in a grid file system, which comprises the steps that: the grid file system acquires metadata used to represent information NStruc of a host user file mount point according to identity information GUInfo of a grid user; the grid file system is subject to the initialization operation, and a metadata table is constructed; a file and the host user file mount point of the file are confirmed through virtual route transformation according to a file operating command; according to information in the metadata table, the grid user is mapped to a host user nU on the host user file mount point of the file; a host searches a corresponding host file according to a file operating command submitted by the host user nU; and the host file is processed according to the file operating command. The method shields the discrepancy among different hosts and / or different file systems through the virtualized representation to the grid file and the grid user-oriented design, and provides convenient and unified grid file processing operation under the condition of not modifying a host file system.

Description

technical field [0001] The invention relates to the field of grid computing, in particular to a simple grid file system in the field of grid computing. Background technique [0002] Grid computing (Grid computing) is to use Internet technology to form a virtual supercomputer from computers scattered in different geographical locations. Each participating computer is a "node" among them, and all computers form a node network. --grid. The computer system composed of grid computing has the advantages of strong computing power and low cost. [0003] Each node in the grid computing environment adopts the file system to realize the management of the file data. The existing file system in the node is a method of storing data. It uses a hierarchical directory structure to store files, which consists of a root directory and many subdirectory files, thus forming a large tree structure. It is a file, A collection of directories and other data structures. Since a file system in an e...
