A digital computersystem was developed for automatic operation of the Toshiba Sodium Test Loops, intended for studying the control system of liquid metal fast breeder reactors. The test installation is controlled by a system of two TOSBAC-40C central process-ing units, which take care of plant monitoring, data logging, information display, sequence control and closed loop control. The operator console linked to the computers can handle more than 3, 000 process input/output signals. The state of the plant and measured data are displayed on two color cathode-ray tube installed on the console. Normal operation of the four loops constituting the installation can be supervised by one single operator. Safety in the case of power failure and other emergencies is assured by a safety protection system that functions independently of the computersystem.

system-level diagnosis for n - star multi-computer systems is considered. In this approach, processors test each other and the test results are collected and analyzed to determine faulty processors. Three basic diagnosis strategies based on this approach are considered for use in n - star: one - t, one - tit, and seq - t. The one - t and one - tit are one-step diagnosis strategies which involve only one testing phase and one repair phase. The goal here is to identify and replace all faulty processors through one mutual testing phase. The other method is sequential diagnosis strategy (seq - t) which involves multiple iterations of testing and repair phases. The cost and diagnostic power of these three basic strategies for n - star is considered. In this paper some new properties of the sequential diagnosis strategy are discussed. In particular, we give a lower bound for the degree of diagnosability of the seq - t strategy in n - star multi-computer system.
