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 present invention provides a method for processing files in a grid file system, comprising: the grid file system acquires metadata used to represent the host user file mount point information NStruc according to the grid user's identity information GUInfo; The grid file system is initialized to construct a metadata table; according to the file operation command, the file and the host user file mount point where the file is located are determined through virtual path conversion; according to the information in the metadata table, the grid user is mapped to the file location The host user nU on the host user file mount point; the host searches for the corresponding host file according to the file operation command submitted by the host user nU; processes the host file according to the file operation command. The present invention shields the differences between different hosts and / or different file systems through the virtualized representation of grid files and the design for grid users, and provides a convenient and unified network without modifying the host file system. Grid file processing operations.

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...
