METHOD FOR CONTROLLING DISTRIBUTED INFORMATION PROCESSING SYSTEM

PURPOSE:To transfer information from computer to computer without the computer software overhead, by writing information which has been received by the communication control eqipment, on the memory of the computer and using the memory units of the respective computers as a shared memory. CONSTITUTION:A communication control equipment 4 of the computer 1 periodically fetches the block contents of the virtual shared memory segment (not shown in the figure) into a frame memory (not shown in the figure), addes the transmission control header thereto and sends them to the transmission line 5. The frame which has been sent to the transmission line 5 is sent again to the transmission line 5. The frame which has been sent to the transmission line 5, is removed from the transmission route when the frame returns to the transmitting device 4, after making one round. By this arrangement, the information which has been set to the memory of the computer 1 is automatically transferred to all other memory units of the computer 1 within a certain limited time. When viewed from the program of the computer, therefore, the operation can be made as if the shared memory were present, which can be accessed in common from all computers.
