Abstract

PURPOSE:To perform failure detection, by assuming a computer out of a composite computer as a master computer, transmitting a check signal periodically from this computer to the other computers, and discriminating the presence/ absence of the abnormity of a response time from a statistics assuming the response time of each computer as a function of an elapsed time. CONSTITUTION:One computer out of a plurality of computers constituting a composite computer system is taken as a master computer and a check signal is transmitted to each computer from this master computer at each prescribed period. The computer receiving this check signal transmits a response signal to the master computer. It is determined that the operation to detect the check signal and to transmit the response signal is not performed to other processing operations with priority. T(t,i) at various points of time is measured as to all the computers, the statistics at the normal operation as to each computer is made in advance, and whether or not the response time newly measured is discriminated from the said statistics.
