It requests the execution of instructions, or outputs job execution results to the output device 3 in response to a job completion notification from the distributed device management means 213.

The distributed device management unit 213 is a unit that manages the distributed processing execution state of the sub-computers that perform distributed processing using the management table 23. The distributed equipment management unit 213 is a unit that manages the distributed processing execution status of sub-computers that perform distributed processing using the management table 23. The sub-computer that is not executing the job is found from the management table 23 and requests the communication control means 214 to send a job execution instruction. Further, when the communication control means 214 notifies the sub-computer of the completion of job execution, it stores in the management table 23 that the job running on that sub-computer has finished;
This is to notify the job management means 212.

The communication control means 214 is a means for controlling communication with a plurality of sub-computers, and transmits data to a sub-computer specified by the distributed equipment management means 213 and sends data from the sub-computers to the distributed equipment management means 21.
3.

Note that the job specified by the job execution instruction is stored in advance in the file device 41/51 on the sub computer side.
・Assume that it is stored in 61.

Next, the operation of the present invention will be explained using a specific example with reference to FIG.

FIG. 2 is a block diagram showing the configuration of an embodiment of the distributed job control mechanism of the present invention. From the input device 1, multiple job execution instructions by JCL (JCL-A 11/JC
If L-B 12/JCL-C13) is inserted,
The job instruction input means 211 receives all the job execution instructions and notifies the job management means 212 of all the job execution instructions.

The job management unit 212 stores the notified job execution instruction in the storage area 22 managed by the job management unit 212.
After that, the job execution instructions stored in the storage area 22 are notified to the distributed device management means 213 one by one. The first thing to be notified is JCL-A 11.
