Apparatus and a method for creating isolated sub-environments using host names and aliases

摘要

In accordance with a preferred embodiment of the present invention, a method and an apparatus is disclosed for providing a corresponding view of a partitioned distributed parallel processing environment. The parallel processing system itself is comprised of a plurality of nodes connected to one another and to a central control element via a network. The central control element is used for communication and status maintenance of the system environment. The apparatus and method provides for separate storing of system data pertaining to different sub-environments in a system data repository located in the central control element. Each data pertaining exclusively to a sub-environment is identified as such and limited access to that data is provided only to the nodes residing in that environment. A system view is constructed based on the data in this repository. Once a view is constructed, the view is identified and stored separately as belonging to a specific sub-environment. A client, or a querying node, is then provided access to its sub-environment's view through the central control element.
