ABSTRACT:
A method of deciphering all communications for a given sub-environment in a partitioned parallel processing environment is suggested through the use of daemons. The parallel processing environment is a UNIX based operating environment comprising of a plurality of nodes connected through a network to one another and to a central control element used for controlling all communications. The parallel processing environment initially operates as a single computing unit, which is later partitioned into two or more isolated sub-environments. The method comprises of storing all system data in a repository provided in the central control element, each data being organized as belonging exclusively to one sub-environment, or globally to all sub-environments. The central control element is then apportioned, so that the data belonging exclusively to one sub-environment is located at a given address, each sub-environment being assigned a different address. A dedicated daemon is then started in the central control element for each sub-environment. The daemon is provided its respective sub-environment's address in the central control element. The daemon "listens" in and deciphers all communications, only returning back those communication pertaining to its sub-environments back to the nodes of its respective sub-environment.
