The design and implementation of the remote file browser (RFB) based on Java/CORBA is introduced in this paper, which is developed for Dawning3000 parallel machine. On traditional parallel machines, users organize and manage the file system through command line interface, which makes users feel very inconvenient. To solve this problem, a GUI-based file browser is implemented to support the access to the file system of parallel machines. The RFB employs client/server mode, and separates GUI from the implementation of the access to file system.Here,GUI is implementes with language and Java GUI Swing package,which make it platform-independent,and communiction between client and server is implementes with currently prevalent CORBA middleware.The RFB supports remote access to the file system of parallel machines within both local area network and wide area network,and hides the differnce of client platform and location of paralle machines,which highly improves the usability of parallel machines.
