A blackboard-based framework for the development of cooperating schedulers

The authors present the design and implementation of a software framework using the blackboard model. This blackboard-based framework is an abstract interface used for the development of cooperating schedulers in a distributed system. The significance of this work is threefold: first, the interesting features of the blackboard model was applied to the area of software modeling; second, an abstract interface was built to distinguish blackboard modeling issues from scheduling issues; and third, a blackboard-based scheduler was implemented efficiently using lightweight processes.<>
