Abstract: In a distributed processing system wherein a plurality of processors are connected through a network and wherein programs are transmitted among the processors; each of the processors monitors the status of a program in the processor or the load status of any other of the processors as indicated by a message on the network. Upon performance of a judgement operator, the processor broadcasts a message indicative of the status of the processor or a program with a content indicating code affixed thereto, to another network, and the processor having received the message broadcasts a program existent in the other processor to the network along with the code indicative of the content of the program. The broadcast is performed in the other processor in accordance with the load statuses of the processors, and upon judging the content of the received message.

Abstract: A resource management method and system for version-up in a multiprocessor system having functions that a processor to be made version-up investigates resources under control by the own processor itself before deciding if any of the resources are to be moved and/or duplicated, that the processor can decide the processors to which the movement and/or duplication of any of the resources is destined, that the resource is moved or duplicated to the destined processor. After that, version-up of the processor to be made version up is executed, thereby effectively using the resources and making version-up while the multiprocessor system is under operation.

Abstract: Several processors and several communication control units are connected to a transmission medium. Each communication control unit has one or more terminal devices connected to it, and so any terminal device can be coupled to any processor. Each processor includes a central processing unit, a memory, and a control manager. The memory stores first information regarding processing being done with a terminal device coupled to the processor and second information regarding the communication control units connected to each of the processors and regarding the terminal devices being serviced by the processor. The control manager manages the communication control units based on the stored information. Information about the connections between the processors and the communication control units is broadcast to all processors. If any processor is faulty, another processor can take over the processing being done by the faulty processor.
