Abstract : The StarLite Project has the goal of discovering a set of design principles and developing efficient algorithms for distributed real-time systems. The initial focus of the project is on scheduling algorithms and database systems. The project also involves the construction of a prototyping environment that support experimentation with concurrent and distributed/parallel algorithms for performance testing. One of the most important achievements in this project is the development of new scheduling algorithms based on the idea of adjusting the serialization order of active transactions dynamically. When compared with conventional transaction scheduling algorithms, our algorithms significantly improve the percentage of high priority transactions that meet the deadline. In addition, we have developed experimental database systems for performance evaluation of new technology. The RTDB server on ARTS kernel is extended to support application programmatic interface, graphic user interface, imprecise computing server, indexing mechanism, and distributed multiple server.
