The Argent Queue Engine supervises the running of a job instance, or an external job. As with all Argent products, the Argent Queue Engine uses no kernel-mode code, and only public APIs. This disciplined engineering approach means the last barrage of service packs will not destabilize Argent, and a new release of the operating system cannot break Argent.

However it is done, when a job is submitted to the Argent Queue Engine, the Argent Queue Engine supervises the running of the job; reporting the status of the job back to the submitted – when queried by the submitter; and terminating the job if requested to do so by the submitter. In summary, all aspects of the life cycle of job are controlled and supervised by the Argent Queue Engine.
