Abstract

A system for loading a program in a distributed processing system including a plurality of information processing units interconnected by a transmission system. An information processing unit prepares a program and sends the program to the transmission system. Another information processing unit receives the program from the transmission system and stores the program in a memory in accordance with a content code of the program. A program based on program may be retrieved from the memory structural information, and sent to the transmission system. Each information processing unit includes a device for sending program structural information to the transmission system, selecting a corresponding program from the transmission system and loading the selected program in the unit.

Dependent claims

A method for loading a program in a distributed processing system including a plurality of information processing units interconnected by a transmission system, comprising the steps of:

storing at least one program and its identifier in a memory of at least one of said information processing units;
transmitting a message from an information processing unit, said message including a request for a program to be loaded into at least one of said information processing units;
receiving said message and retrieving at least one stored program and its identifier based on said message from a memory of at least one information processing unit other than said information processing unit sending said message;
transmitting said at least one stored program and its identifier retrieved from said memory;
and
selecting a program on the basis of said identifier from said at least one stored program being transmitted and loading the selected program in a memory of at least one information processing unit other than said information processing unit transmitting said stored program and identifier.
