This chapter first reviews existing parallel and distributed processing models and technologies for comparison with the chosen Spatial Grasp Technology (SGT) for this book which is based on distributed and parallel processing, management, and control too. It then describes the general features of SGT and its basic Spatial Grasp Language (SGL) with its top summary, main components, and control states. It explains how SGL scenarios evolve and provides details of the networked language implementation, as well as components of the distributed SGL interpreter.
