An exercise system includes a plurality of exercise terminals, wherein a workout of an exerciser includes at least two exercises performed at one or more of the exercise terminals. The stylus communicates with the touch screen device to report stylus operating information from onboard sensors, and to receive application program instructions defining feedback and friction forces to be applied by onboard actuators. The portable memory solution also provides mobile access to the user’s applications and personal data files. The system according to the present embodiment further comprises a controller operative to receive a pipeline specification that identifies the one or more pipelets as belonging to a pipeline, generate a dependency map that identifies an order in which to execute the one or more pipelets and execute the pipelets according to the dependency map to generate a result.
