Abstract

PURPOSE:To prevent the scale of a program increased and the program complicated by eliminating a synchronous processing by software by performing the synchronous operations of the programs with synchronizing instructions on plural central processing units. CONSTITUTION:Firstly, the program 4 is developed on the central processing unit 2, and the program 5 is developed on the central processing unit 3. And the program by which the synchronizing instruction 6 in the program is executed first is stopped, and simultaneously, the execution of the synchronizing instruction is informed from a synchronizing primitive detecting means 7 to the synchronization managing means 9 of a service processor 8. The program to be executed next stops its execution when it executes the synchronizing instruction 6, and the execution of the synchronizing instruction 6 is informed to the synchronization managing means 9 with the synchronizing instruction detecting means 7, and the synchronization managing means 9 discriminates synchronous information stacked on the plural central processing units. Then, the instruction next to each synchronizing primitive 6 can be automatically restarted with a program restart means 10 by taking the synchronization of the programs 4 and 5. In such a way, it is possible to prevent the scale of the program increased and the program complicated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program synchronization processing method for an information processing device.

[Conventional technology]

Conventionally, in a program synchronization processing method for an information processing device, a method has been adopted in which a program is executed on a plurality of central processing units and the synchronization processing is performed in the processing within the program.

[Problem to be solved by the invention]

In the conventional program synchronization processing method described above, the synchronization processing between programs is performed by software, and therefore, programs that frequently use synchronization operations become larger and more complex.

Furthermore, when a test diagnosis program requires extremely delicate synchronization operations such as in a competitive test, there is a drawback that test failures may occur.

[Means to solve the problem]

The program synchronization processing method of the present invention specifies a synchronization position on a plurality of programs developed on the information processing device in an information processing system comprising an information processing device having a plurality of central processing units and a service processor. A synchronization command for stopping the own program, a synchronization command detection means for detecting the synchronization command, a synchronization management means for managing synchronization of the synchronization commands detected by the synchronization command detection means, and synchronization by the synchronization management means. and program restart means for restarting the program again.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a program synchronization processing method according to the present invention. In FIG. 1, the program synchronization processing system includes central processing units 2 and 3, a program 4 including a synchronization command 6, an information processing device 1 having a synchronization command detection means 7, a synchronization command management means 9. and a service processor 8 having program restart means IO.

First, the program 4 is developed on the central processing unit 2, and the program 5 is developed on the central processing unit 3. Program 4
Each program is executed simultaneously with the synchronization instruction 6 pre-installed in the program 5.

Next, the program that executed the synchronization instruction 6 earlier in either the program 4 or the program 5 being executed is stopped, and at the same time, the synchronization instruction detection means 7
The synchronization management means 9 in the service processor 8 is notified that the synchronization command 6 has been executed. The synchronization management means 9, which has received the notification that the synchronization command 6 has been executed, stacks the received synchronization information and monitors the detection of the synchronization command 6 of the corresponding program.

Next, the corresponding program stops its own program when the synchronization command 6 is executed, and the synchronization command detection means 7 notifies the synchronization management means 9 that the synchronization command 6 has been executed.
Upon receiving the synchronization information, the synchronization management means 9 determines the stalled synchronization information of the plurality of central processing units, synchronizes the programs 4 and 5 with the program restart means 10, and executes the next synchronization command 6. Automatically resumes from command.

〔Effect of the invention〕

As described above, according to the present invention, synchronization of programs on a plurality of central processing units is performed using a synchronization command, thereby eliminating the need for synchronization processing by software. Therefore, it is possible to prevent an increase in the program size and the complexity of the program, and also to make it possible to perform extremely delicate synchronization operations that cannot be done with software in competitive tests in the test diagnosis program, and to efficiently utilize the resources of the information processing equipment. It is effective in making delicate test diagnoses.
