Using massive parallelism, ICOT appears about to achieve its stated goal of 100 million logical instructions per second (LIPS) of theoretical peak performance. The Fifth Generation Project achieved its goal of training a new generation of computer technologists.
ICOT's experiments in parallelism have made an important contribution to parallel computing. ICOT is one of only a few sites in the world that is studying massively parallel symbolic computing.
ICOT created the funding and motivation to spur significant interest worldwide in AI, KBS and advanced computing paradigms.
The logic-based language, KL1, has been shown to work well as a programming language for parallel computing; together with the operating system PIMOS, KL1 does a good job of automatic load distribution. However, KL1 and PIMOS are unlikely to gain adherents outside the logic programming community. ICOT's logic programming research is world class, probably the best in the world.
On the negative side, ICOT has made little progress in the applications dimension. ICOT has had little impact on knowledge-based systems technology. The choice of PROLOG and logic programming has isolated ICOT from industry. The ICOT machines are research-only designs. Their high cost has prevented distribution outside of ICOT, and consequently has isolated ICOT from the industrial and commercial communities.
A successor project, called the Real World Computing (RWC) Project, was initiated in April 1992. It does not include knowledge-based systems within its scope.
