Description/Abstract The military has a demonstrated need for knowledge-based systems with significantly higher quantitative performance.^The current hardware and software architectures for knowledge-based systems cannot support such requirements.^Based on near-term projections for integrated-circuit technologies, it is clear that highly parallel multiprocessor computers consisting of 100s to 1000s of processors and realizing a variety of concurrent architectures can be built.^The most-promising approach for achieving orders of magnitude improvement in the quantitative performance of knowledge-based systems is by exploiting concurrency on multiprocessor systems.^The major issue is whether such computer systems can be effectively used to enhance the performance of knowledge-based systems.^Expert systems on Multiprocessor Architectures project is addressing the following questions: (1) Can multiprocessor computers be used to achieve significant execution speedup (two to three orders of magnitude) over serial machines for knowledge-based system applications.^(2) What are the limiting factors in achieving speedup for such systems.^(3) What are appropriate software models and methodologies for programming such systems.^(4) What are appropriate hardware architectures for supporting such systems.^Given the lack of any formal foundations for studying concurrent knowledge-based systems, the approach taken to answering these questions is empirical rather than theoretical.
