Abstract: The invention relates to a system and a method for tracking and executing a job comprising a series of tasks. Each task is executable on a separate computing device. The method comprises: utilizing a workload manager to identify an initial schedule of implementation for the job; utilizing agents to selectively control execution of the tasks; and for each agent, utilizing a publish/subscription interface to isolate communications of the workload manager from each agent and to communicate with other publish/subscription interfaces of other agents to determine when to activate its task. The interface utilizes a broker adapted to communicate with other brokers to disseminate communications amongst the agents.
