The fundamental objective of the National PARALLEL PROCESSING RESEARCH COUNCIL is to foster cooperation among industry, university, and government bodies in support of research and development on parallel computing systems. Such cooperation is considered essential to expand more rapidly both the understanding of hardware and software concepts and their utilization in development of actual computing systems.This proposal attempts to specifically identify the responsibilities and activities of an Executive Committee for the National PARALLEL PROCESSING RESEARCH COUNCIL.

Computer security violations have become a serious threat to both corporate and national defense activities. By extending the work done by Myers et. el. in the development of the capability based addressing system for the SWARD at IBM, a Computer architectural approach has been developed which solves all known software based internal computer security problems. The problems solved include (but are not restricted to):(1) Violations of priority and access priveleges by highly skilled users,(2) The clasic "Trojan Horse" problem,(3) Access and alteration of sensitive data-bases by unauthorized users(4) The "Lost Key" problem of advanced capability based addressing systems.This solution proposes and develops an architectural approach which manages a sophisticated capability based addressing system entirely in hardware. As a result, the architectures developed by this approach tend to be somewhat hardware intensive in that they require unusual amounts of control and memory not available to any user (it is maintained soley for security purposes).
