Abstract: This paper discusses in detail the design and implementation of Poligon, a concurrent blackboard system, documenting our progress and the problem areas we identified in the process of developing it. It also considers the factors that aid and those that limit the performance of blackboard systems in general and of concurrent blackboard systems in particular, relating these factors to the implementation of Poligon.
