ICOT, Japan’s Institute for Computers Of Tomorrow, has set as its next goal the design, by March 1989, of the world’s fastest parallel processing machine, to be called PSI2, containing 64 parallel processor boards, and capable of 2 MegaLIPS, Logical Inferences Per Second: to be designed to be programmed in Prolog only, the PSI2 will be the successor to ICOT participant Mitsubishi Electric’s PSI Prolog machine, which is a board-level CPU with 256Kb memory; the PSI2 will be built of custom VLSI processors with 1Mb memory taking a third the space and delivering three times the processing speed.
