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. Each processor judges whether or not the program being broadcast corresponds to a function necessary for a process of the processor based on the code indicative of the content of the program. If the program is needed, the processor loads and executes the program.
