SBIR-STTR Award

This proposal describes the investigation of techniques to achieve efficient and reliable distributed processing using the ada programming language and specifying parallelism by utilizing the ada task model. The intent is to support transparent distribution which will allow software functionality to migrate among processors within a local area network to achieve performance and fault tolerance requirements. Areas of particular concern which will be addressed are: the way in which tasks and data re associated with processors; a configurable network interface which can support the requirements of the ada runtime; nd access to shared data among distributed tasks. Also addressed are tools to support debugging distributed systems as well as to monitor the performance and assist in prediction of overload conditions.

This project will conduct research and devleopment on a Distribute Target Ada Program Support Environment (DT/APSE) product. The DT/APSE is a set of software tools and runtime routines which support the life cycle software engineerinhg for distributed systems programmed in Ada. The end objhective of this project is to advance the state of the practice in the developmetn of software for distributed systems. Unlike many other approaches toward paral;lel computing, this advancement will be made in an upward compatible way by utilizing the Ada programming language. We believe this compatibility is absolutely necessary to preserve the substantial investment by the U.S. Government and the benefits of international standardization achieved by Ada.
