FAULT MONITORING SYSTEM

PROBLEM TO BE SOLVED: To accurately grasp failures generated in a large scale parallel computer system in the order of generation time series. SOLUTION: The failure monitoring system is provided with a plurality of nodes 10 being respectively independent computers, cross bar data switches 20 for switching a signal route between the nodes, a cross bar controller 30 for controlling the drive of the switches 20, slave service processors 40 connected to the nodes 10, the switches 20 and the controller 30 and allowed to monitor failures and output prescribed failure information immediately after detecting a failure, and a master service processor 50 for monitoring the generation time series of the failure by receiving the failure information.
