Abstract: A synchronization manager interface determines a first state of execution of an application task executing on a first controller at defined synchronization points and further determines a second state of execution of the application task executing on a second controller at the defined synchronization points. The synchronization manager interface, when executed, configures the first controller to transmit the first state from the first controller to the second controller via a communications channel established between the controllers for verifying a successful synchronization of the application task on the controllers based on a comparison of the first state with the second state.
