Abstract

PURPOSE:To ensure the satisfactory ability and to improve the processing efficiency in a data processing system by transmitting and receiving data via a communication circuit and performing the local processing and the system processing in parallel with each other via a data processor of the slave side. CONSTITUTION:When the jobs that can be processed in parallel with each other are prepared at a main data processor 1, these jobs are automatically sent to each data processor 103 via a communication circuit 5. Thus the jobs are processed by the processors 103 and collected. Then each processor 103 ends the job that was executed in parallel with the job executed locally by the processor 103 itself and then transmitted. In such a constitution, the satisfactory ability is ensured with each processor 103 in a data processing system where the data can be transferred between the data processors with no manual intervention.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a data processing system in which a plurality of data processing devices such as electronic computers and personal computers are connected by a LAN (Local Area Network). It is something.

(Prior art) Conventionally, when executing multiple jobs that take several hours to process, multiple personal computers are prepared, and an operator or the like inputs necessary data and sets conditions on the main personal computer. , create a processing program (including data) that can be executed on each personal computer, and load it onto an FDD (floppy disk) for each job.Next, set this FDD into each prepared personal computer and run the program. The processing results are written to the FDD again.

Next, the FDDs on which the processing results are written are sequentially set in the main personal computer to absorb the processing results, and the overall processing results are summarized in the main personal computer.

However, according to such a data processing system,
There has been a problem in that an operator must always intervene when transferring data between the main personal computer and other computers, which is cumbersome.

In addition, personal computers are usually operated as word processors according to the operator's instructions, but such use is a way of putting a load on the personal computer, and does not allow the personal computer to use its full capacity efficiently. The problem was that it wasn't fully utilized.

(Problems to be Solved by the Invention) As mentioned above, in conventional data processing systems, data is transferred between each data processing device via a storage medium such as an FDD, which requires operator intervention and is cumbersome. There was also a problem that when each data processing device operated independently, it was not able to make full use of its capabilities efficiently, and there was a need to solve these problems together.

The present invention was made to solve the problems of such conventional data processing systems, and its purpose is to fully utilize the capabilities of each data processing device, and to improve communication between data processing devices without human intervention. An object of the present invention is to provide a data processing system that enables data transmission and reception.

[Structure of the Invention] (Means for Solving the Problems) In the present invention, a data processing system in which a plurality of data processing devices perform data communication with each other via a communication line, allows other data processing devices to perform data communication with each other via a communication line. A main data processing device that sends data related to processing to the communication line and receives the processed results, and a data processing device that sends data related to processing sent from the main data processing device in the background of a job that is executed locally. A data processing system was constructed by including a child data processing device that receives the data, executes the corresponding processing in parallel, and sends the processing results to the main data processing device.

(Function) According to the above configuration, when multiple jobs capable of parallel processing are prepared in the main data processing device, each job is automatically sent to each data processing device via a communication line and collected after execution. Since each data processing device finishes the sent job by executing it in parallel with the job that it executes locally, it is also possible to make full use of its capabilities.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a system configuration diagram of an embodiment of the present invention. In the figure, 1 indicates a main personal computer, which is used, for example, for accounting purposes.

2 to 4 indicate child personal computers, for example,
Assume that it is being used as a word processor. These personal computers 1 to 4 are interconnected via a LAN 5. The LAN 5 is, for example, Ethernet, and uses the C8MA/CD system. The personal computer 1 includes an unprocessed information sending means 11 that sends the contents of processing to be executed to the necessary personal computers 2 to 4 when necessary, and processing result information sent from the personal computers 2 to 4. Processed information receiving means 12 that receives and edits the information.
and a communication interface section 13 provided with various layers for performing communication in the C8MA/CD method. On the other hand, the personal computers 2 to 4 include a communication interface unit 101 that is the same as the communication interface unit 13 (equipped with various layers for executing communication in the C8MA/'CD method), and local processing of the device (here,
a local processing execution means 102 that executes processing (processing as a word processor); a system processing execution means 103 that executes processing given from the main personal computer l; A processing switching means 104 is provided for switching the processing so that the processing is executed in parallel in the background.

Initially, personal computers 1 were used by operators for accounting purposes, inputting data such as deposits and withdrawals, and performing necessary processing.
is used as a word processor. One of these days,
Assume that a plurality of jobs are generated on the personal computer 1 to create the accounting status of each department. Then, the operator instructs the personal computer 1 to cause each of the personal computers 2 to 4 to execute the job. The subsequent operation of the system will be explained based on the flowchart in FIG.

First, when the above execution instruction is input (201).

Personal computers 2 to 3 each perform only processing A to C as a word processor using local processing execution means 1.
02 is running. Assume now that a job generated by the personal computer 5 is divided into processes X to Z, and that the programs are programmed to be divided and executed by the personal computers 2 to 4, respectively. Then, the unprocessed information sending means 11 transmits the unprocessed information (for example, the processing procedure,
The content of the program) is given to the communication interface section 13 to be sent to the personal computer 2 (202). As a result, the communication interface section 13
Pre-processing information is given to the communication interface unit 1011 of the personal computer 2 via the AN 5, and is given to the system processing execution means 103 and the processing switching means 104 to prepare for processing. Next, the processing content The means 102 is switched to operate using the gap between processing A, and processing X is performed. As a result, the personal computer 2 performs processing A and processing X in parallel, functions as a word processor, and performs processing X related to accounting. Thereafter, the pre-processing information, processing contents, and start command for process Y are similarly given to the personal computer 3 (205, 206).

207), and pre-processing information, processing contents, and start command regarding processing Z are given to the personal computer 4 (208, 209, 210). As a result, in the personal computer 3, processing B and processing Y are processed in parallel, and in the personal computer 4, processing C and processing Z are processed in parallel.

When the processes X to Z are completed on the personal computers 2 to 4, the processing results are transferred to the personal computer 2.
- 4 to the main personal computer 1 (211, 212, 213), and the processed information receiving means 12 of the personal computer 1 receives it and performs processing such as editing. On the other hand, the personal computers 2 to 4 return to performing the processes A to C of the local processing means 102 only.

In addition, in this example, we have shown that the system can be changed flexibly by sending not only the data of the processing content but also the processing method etc. (program). , each data processing device may be provided with a program for the processing method, and in this way, the transmission time is reduced accordingly, making it possible to speed up the data processing.

[Effects of the Invention] As explained above, according to the present invention, since data is sent and received via a communication line, there is no need for human intervention. Since the processing is performed in parallel with the processing, it is possible to fully utilize the capacity and use it efficiently.
