Abstract
During execution, API calls to the operating system in a master processor are transferred to slave processors by an event redirection mechanism, the API calls are then provided to the operating systems of the slave processors by their event redirection mechanisms, such that the same screen or window appears at both the master processor and slave processors. Messages generated at the slave processors are likewise provided to the message queue of the master processor by the event redirection mechanism, and then provided to the application running on the master processor. Therefore the slave processors share the application of the master processor.
