Abstract
A parallel-processing apparatus has information-processing apparatuses coupled mutually through an optical transmission line having channels. Each of the information-processing apparatuses has processors allocated to the channels of the optical transmission line, a controller and a display. When one of the processors detects a channel failure, the processor notifies a processor in the other information-processing apparatus of the channel failure, notifies the controller of the information-processing apparatus of the channel failure and notifies the controller of the information-processing apparatus of the notification of the channel failure from the other information-processing apparatus. The controller causes the processor of the information-processing apparatus to stop use of the failing optical transmission line based on reception of the notification of the channel failure and sets the display corresponding to the failing optical transmission line to have a stop indication state indicating that communication through the optical transmission line has stopped.
