Abstract

PURPOSE:To reduce the burden of an operator and to shorten an executing time by transferring and activating a control program and a testing program, which are loaded under the control of a first CPU, under the control of a second CPU. CONSTITUTION:A multiprocessor testing flag which indicates the multiprocessor testing program is hoisted, and the control program and the multiprocessor program, which are loaded under the control of a first CPU 100, are transferred under the control of a second CPU 200, and the second CPU is activated. Thus, the burden of the operator is reduced, and the title loosely coupled multiprocessor testing system whose executing time is shortened can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a test method for a loosely coupled multi-ten setter in which a plurality of CPUs perform processing under a plurality of management programs.

[Conventional technology]

Conventionally, as a test method for this type of loosely coupled multiprocessor, a management program is started from each of a plurality of processors, and a loosely coupled multiprocessor test is loaded and started under each management program.

[Problem to be solved by the invention]

In the conventional loosely coupled multiprocessor testing method described above,
The disadvantage is that the operator has to move between consoles connected to multiple CPUs to start up the management program and load the program, and it takes time to prepare for the test because there are many operations. be.

In view of the above-mentioned drawbacks, the second technical object of the present invention is to provide a loosely coupled multi-gauge processor test method that reduces the burden on the operator and shortens the test execution time.

[Means to solve the problem]

According to the present invention, in a test method for a loosely coupled multiprocessor in which a plurality of CPUs perform processing under a plurality of management programs, a multiprocessor test flag indicating that the program is a multiprocessor test program is set, and a first CPU
A loosely coupled multiprocessor test method is provided in which a management program and a multiprocessor test program loaded under the control of a second CPU are transferred to the control of a second CPU, and the second CPU is activated. It will be done.

〔Example〕

Next, two embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1, the embodiment includes a first CPU Zoo,

First console 112. First main storage device 120. Management program load area 121. Loading means 122. Checking means 123. Program transfer means 124. Register setting means 125. Starting means 126, register group storage area 127. Test program load area 128. Multiprocessor test flag 1291 diagnostic control unit 130. 1st
diagnostic bus 131, first bus adapter 140. first processor path 150m second CPU 200. Second peripheral control device 210, second DISK 211, second
console 212. Second main storage device 22o, second diagnostic bus 23L, second bus adapter 240. It consists of a second processor bus 250.

Next, an outline of the operation of the embodiment will be explained with reference to the drawings.

In the loosely coupled multiprocessor test method of the present invention, when the system is started up, the second CPU 200 is in a stopped state, and under the control of the first CPU 100, the first DI
A management program is loaded from the SKIII to the management program load area 121 on the first main storage device 120 through the first peripheral control device 110 and the first processor bus 150, and the following processing is performed.

If a multiprocessor test is specified by a load command from the first console 112, the loading means 122 loads the data from the first DISK 111 to the first peripheral control device 11.
0 and the first processor bus 150 into the test program load area 128 on the first main memory 120 . Next, when a test start command is input from the first console 112, the checking means 123 checks the multiprocessor test flag 129 of the multiprocessor test loaded into the test program load area 128. When the multiprocessor test flag 129 indicates a multiprocessor test, the program transfer means 124 transfers the program to the first main memory 120.
The upper management program load area 121 and test program load area 128 are connected to the first processor bus 150, the first bus adapter 140, and the second path adapter 240.
and the processor bus 250 of WJ2, and onto the second main storage device 220. Next, register setting means 1
25 executes the diagnostic instruction and stores the register group storage area 127.
The programmable registers stored in the first
through the processor bus 150 , the first CPU too, the first diagnostic bus 131 , the diagnostic controller 130 and the second diagnostic bus 231 .

Load into second CPU 200. Next, starting means 1
26 operates the clock of the second CPU 200 and starts a multiprocessor test in the test program load area 128. At this time, the second CPU 200
The management program stored in the second main storage device 220 starts processing with the program-controllable register values of the registers loaded in the register, and starts the multiprocessor test stored in the second main storage device 220. do.

To summarize the above embodiment, a program loading means loads a multiprocessor test program including multiprocessor test flag information indicating that it is a multiprocessor test program from an external storage device into a first main memory.

A check means for checking a multiprocessor test flag of the loaded program, and if the loaded program is a multiprocessor test, a management program and the loaded multiprocessor test program.

a program transfer means for transferring onto the second main memory;
A loosely coupled multiprocessor test method is obtained, which is characterized by having register setting means for setting the registers of the second CPU, and processor starting means for starting the clock of the second CPU.

〔Effect of the invention〕

As explained above, the present invention provides a method for testing a loosely coupled multiprocessor in which multiple CPUs perform processing under multiple management programs, in which a management program and a test program are loaded under the control of a first CPU. and the second C
Transferring and activating the program under the control of the PU has the effect of reducing the load on the operator and further shortening the execution time.
