Abstract : We have begun porting the SIMD Parka system to more generic MIMD machines. The system has been recoded in C and supported using runtime optimization packages developed in the high performance computing laboratory at Maryland. New 'scanning' algorithms have been developed for inheritance and recognition inferences. These algorithms have been tested with both random networks and on a recoding of the ontology of the CYC knowledge base. Tests show that the new version is significantly faster than the SIMD system, and that it promises to scale well to knowledge bases orders of magnitude larger than CYC.
