Implementation of a hierarchical control system on a BBN butterfly multiprocessor: initial studies and results

This report discusses the introductory work with implementing a parallel version of a hierarchical control system named CAOS (Control using Action Oriented Schemata) on the BBN Butterfly Multiprocessor. First, an overview of the BBN Butterfly and how the control system can utilize the parallel processor is given, followed by a discussion of a partial implementation and future work. Finally, a more extensive overview of the Butterfly hardware and comments on the operating system Chrysalis and the Uniform System functions are included.
