構成である。The processor status collection method of the present invention is implemented in a multiprocessor system using an optical bus having a broadcast transmission function.
When one processor fails and restart processing is performed, a restart start signal is sent to another processor using the broadcast transmission function of the optical bus, and the other processor that receives the restart start signal The state is updated to an out-of-service state, and when the restart processing is completed in the failed processor, a restart end signal is sent to the other processors using the broadcast transmission function of the optical bus, and the restart end signal is received. The other processor updates the state of the faulty processor to an in-service state, the other processor notifies the state of its own processor by a restart end response signal, and the faulty processor that has received the restart end response signal updates the state of the faulty processor to an in-service state. The configuration is such that the state of the other processor that has transmitted the restart completion response signal is updated to an in-service state.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
