System for preserving logical partitions of distributed parallel processing system after re-booting by mapping nodes to their respective sub-environments
First Claim
1. In a distributed parallel processing system environment having a plurality of nodes connected to one another via a network in a manner as to form a single system unit initially, said environment being then logically partitioned into at least two sub-environments, a method of preserving said logical partitions after re-booting, said method comprising the steps of:
- controlling and maintaining all communications and status information between nodes through a central control element connected to said nodes via said network;
storing all system data in a system data repository located in said central control element;
using said stored data, creating a special configuration object class file in said system data repository, said object class file mapping said nodes to their respective sub-environments; and
retrieving any portion of said system data relating to configuration and providing it to each node after rebooting completion.

Abstract
In accordance with a preferred embodiment of the present invention, an application and method of preserving persistent logical partitions, is suggested for use in a partitioned massively parallel processing system environment. All system data, including configuration data is stored in a central control element in a special configuration object class file. The configuration object class file maps the resources to different sub-environments. Upon a system shut-down or re-booting of any resource, the configuration information stored in the central control element is recovered to re-establish the sub-environments integrity.

12. In a distributed parallel processing environment having a plurality of nodes connected to one another via a network in such way as to form a single system unit, said environment logically partitioned into at least two sub-environments, a method of restoring a node to its respective sub-environment after a node re-boot, said method comprising the steps of:
-
controlling and maintaining all communications and status information between said nodes through a central control element connected to said nodes via said network; storing all system data in a system data repository located in said central control element; using said stored data, creating a special configuration object class file in said system repository, said configuration object class file mapping said nodes to their respective sub-environments; and retrieving any portion of said system data relating to configuration information and providing it to any node after re-booting completion. - View Dependent Claims (13, 14)

17. A distributed parallel processing system environment having a plurality of nodes connected to one another via a network in such way as to form a single system unit, said environment further partitioned into at least two logically persistent sub-environments comprising:
-
a central control element for controlling and maintaining all communications and status information between said nodes, said central control element connected to said nodes via said network; a configuration data repository for storing all configuration data located in said central control element; and a system object class file created in said repository for storing configuration data, said system object class mapping all said nodes to their respective sub-environments. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
