A system for distributed task execution

摘要

A method for use in a distributed network (32) for processing a knowbot program (60) that has the ability to move from node to node in the distributed network (32). In the method, a knowbot operating environment (50) in each of the nodes provides service facilities useful to the knowbot program (60). And, in the knowbot operating environment (50), a supervisor process (42) is run that enables the knowbot program (60) to make use of the service facilities but does not permit direct access by the knowbot program (60) to facilities of the knowbot operating environment (50).
