In order to support the unified management of wide area and heterogeneous resources and realize a single virtual machine, a method of implementing a single image file system based on distributed object technology is proposed. A distributed object model is established. Context objects and file objects are defined. This paper discusses the organization structure and implementation technology of a single image file system and gives the performance of common operation command of a single image file system. The single image file system maps the wide area heterogeneous resources of geographically distributed, different management domains and different nodes To the virtual directory system to support the coordinated management of wide-area resources and unified scheduling, to provide users with convenient and practical tools and commands, thus simplifying the operation of the meta-computing system
