Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program processing resource measuring apparatus applied to a program simulator for simulating (pseudo-execution) an operation (execution of a program) of a computer system such as an electronic exchange.

Various processing resources (processing execution memory for program execution, device control management memory, etc.) used in a multi-processing program such as exchange processing, when the number of them is large, cause congestion of internal processing and processing delay. It is inefficient because it causes inability to process and, in the worst case, it causes a system outage, and in the few cases, it does not use it despite its potential. It is necessary to set an appropriate number for the equipment to be processed (target machine), and there is a demand for a technique for obtaining this easily and efficiently.

[0003]

2. Description of the Related Art The following methods have been conventionally adopted to optimize the number of processing resources.

(1) A program to be measured is manually analyzed on a desk, and for each processing resource, the number of reserved steps, which is the number of machine instructions to be executed from the acquisition to the release of the processing resource, is counted, and this reserved step number is calculated. By accumulating the average instruction execution time, the hold time required from the capture to release of the processing resource is calculated, and based on this hold time, the appropriate number of processing resources is calculated according to a predetermined relational expression.

(2) A program to be measured is embedded with a support program for measuring the number of holding steps in advance, and the program to be measured including this is executed as necessary, the holding time is calculated, and processing resources are stored. Calculate the appropriate number.

(3) The running time of the program to be measured is monitored by a hardware dedicated monitoring device connected to the bus to calculate the hold time and the appropriate number of processing resources.

[0007]

However, since there are generally several tens to several hundreds of processing resources, the above-mentioned prior art has the following problems.

(1) In the case where the program to be measured is manually analyzed on a desk, since such a work is extremely complicated, the number of man-hours is large and it takes a long time to obtain the measurement result. .

(2) When the support program is embedded in the program to be measured, it is necessary to embed the support program corresponding to each program to be measured. Since it requires remodeling, it differs from the actual program environment.

(3) With the above-mentioned monitoring device,
A dedicated hardware device is required, and work such as setting measurement points is complicated. Therefore, an object of the present invention is to provide a program processing resource measuring device that can easily and efficiently optimize the number of processing resources without adding or modifying the measured program. .

[0011]

Among the inventions disclosed in the present application, a typical one will be briefly described with reference to FIG. 1 as follows.

That is, the program processing resource measuring apparatus of the present invention includes a measured program storing means 1 in which a measured program is stored and a machine instruction of the measured program, which are pseudo-executed sequentially to include an execution address. The simulation execution means 2 for collecting execution history, and the reserved measurement data storage means 3 in which processing resource reserved measurement data including capture conditions and release conditions for a plurality of processing resources used by the measured program are stored in advance. ing.

Further, it is detected whether the execution address of the machine instruction pseudo-executed by the pseudo-execution means 2 conforms to the capture condition of the processing resource reservation measurement data, and the pseudo-execution means 2 makes pseudo-execution. Processing resource check means 4 for detecting whether or not the execution address of the machine instruction that has been executed in a physical manner meets the release condition of the processing resource reserved measurement data, and the processing resource captured / released by the execution of the measured program. Processing resource data collecting means 5 for collecting processing resource measurement data including the number of pending steps, which is the total number of machine instructions executed from the detection of detection by the processing resource check means 4 to the detection of release. .

The pseudo execution means 2 pseudo-executes the machine instruction of the measured program of the measured program storage means 1,
The processing resource check means 4 checks whether or not the execution address of the machine instruction matches the capture condition or release condition of the reserved measurement data storage means 3, and sequentially repeats these processes for the next machine instruction. When the execution address matches the capture condition, the processing resource data collecting means 5
Starts counting the number of machine instructions executed by the pseudo execution means 2. If the execution address meets the release condition,
The processing resource data collection means 5 finishes measuring the number of executed machine instructions, and thereby the number of reserved steps is obtained.

An average instruction execution time is added to the number of holding steps to calculate a holding time required from capturing to releasing the processing resource, and based on the holding time, an appropriate number of processing resources is calculated according to a predetermined relational expression. To calculate.

By using the program processing resource measuring device according to the present invention, the number of holding steps can be automatically obtained without any modification of the program to be measured. The number of pending steps can be obtained in a short time as well as the number is extremely small, and the number of processing resources can be optimized easily and highly efficiently.

FIG. 2 is a block diagram showing the overall configuration of an embodiment of the present invention, and shows a program simulator to which the program processing resource measuring device of the present invention is applied.

In the figure, 11 is a command control unit, and 12 is a resource management flag storage unit. The command control unit 11 registers a command analysis function 11a for analyzing a command input by the operator and a resource management flag for registering whether or not to measure the processing resource according to the input command (in the case of “0”, the measurement is not registered and measurement is not performed. It has a program processing resource registration function 11b for setting in the resource management flag storage unit 12 that the measurement is carried out by registration if not performed (1).

Reference numeral 13 is a measured program stored in the measured program storage section, and the measured program 13 is
For example, as shown in FIG. 3, an execution unit 13a including a plurality of programs A, B, C, etc. and the execution unit 13a.
Is configured by a resource management unit 13b that manages the processing resources [process execution memory (transaction) for program execution, device control management memory (trunk), etc., of which there are several tens to several hundred types]. FIG. 3 shows that the process execution memory (XXTR) is captured by the program B and the process execution memory is released by the program A.

In FIG. 2, reference numeral 14 is a simulation execution unit, and the simulation execution unit 14 includes an operand read function 14a, a machine instruction pseudo function 14b, a program execution history collection function 14c, a processing resource check function 14d,
A processing resource data collection function 14e is provided.

Reference numerals 15, 16 and 17 denote data stored in corresponding storage units, 15 denotes processing resource reservation measurement data, 16 denotes processing resource status data, and 17 denotes processing resource measurement data.

The processing resource reservation measurement data 15 is data including a capture condition and a release condition for each of the plurality of processing resources used by the measured program 13. More specifically, as shown in FIG. 4A, for each processing resource used by the measured program 13, the absolute address of the acquisition execution unit (acquisition execution program) and the processing resource are set as acquisition conditions. Of the processing execution resource, the absolute address of the release execution unit (release execution program) and the resource identification are set as release conditions. The processing resource reservation measurement data 15 is data that is known at the design stage of the measured program 13, and is created in advance and set in the corresponding storage unit. In FIG. 4 (A),
For example, process execution memory table (transaction)
As the acquisition condition of the processing resource XXTR, the address (23D5B), the resource identification (RID = R
6) and the resource number (RNO = R5).

The processing resource status data 16 is data created and used during the processing by the simulation executing unit 14, and is a resource status flag indicating the status of each of the plurality of processing resources used by the measured program 13. 16a and a resource reservation counter 16b that sets a counter for the number of reservation steps. More specifically, as shown in FIG. 4B, the status flag 16a includes "1" (HUNT) indicating that the processing resource is captured and "2" indicating that the processing resource is released. , (0) (O) indicating other cases
THER), resource identification (RID), and resource number (RNO) are set by the processing resource check function 14d. The resource suspension counter 16b starts counting when a processing resource is captured, increments "1" each time a machine instruction is pseudo-executed, and ends counting when the processing resource is released. It is set by the resource data collection function 14e. When the measurement processing is completed, the resource holding counter 16b has the counter value as the number of holding steps as a measurement result.

The processing resource measurement data 17 is shown in FIG.
As shown in (C), for each of the processing resources acquired and released by the execution of the measured program 13, the program name and the acquisition request address of the measured program 13 that requested acquisition of the processing resource, This is data in which a program name and a release request address that have requested release of processing resources and a pending step number counter are set.

Thus, the operator inputs to the command control section 11 the specification of the measured program 13 and the specification of the processing resource reservation measurement data 15 corresponding thereto. Next, in the case of measuring the processing resource, when the command corresponding to this is input, the command analysis function 11a of the command control unit 11 analyzes it, and the program processing resource registration function 11b registers it in the resource management flag 12. Is set to "1". When the processing resource is not measured but only the simulation of the measured program 13 is performed, a command corresponding to this is input, and the command analysis function 11a of the command control unit 11 analyzes it and registers the program processing resource. The function 11b sets “0” indicating non-registration in the resource management flag 12.

In the simulation executing section 14, the operand reading function 14a reads a machine instruction (execution instruction) from the measured program 13, and the machine instruction pseudo function 14b.
Executes the machine instruction in a pseudo manner. The program execution history collection function 14c collects an execution history (execution address, register value, etc.) associated with the pseudo execution of the machine instruction, stores the execution history as program under test execution history data 18 and stores the execution address. It is passed to the processing resource check function 14d.

The processing resource check function 14d checks the resource management flag 12 and, in the case of registration "1", passes it from the program execution history collection function 14c to the acquisition condition or release condition of the processing resource of the processing resource reservation measurement data 15. It is checked whether or not the executed execution address matches, that is, whether or not the absolute address of the capture condition or the release condition matches the executed address.

When the absolute address of the capture condition matches the execution address, the status flag 16a for the processing resource of the processing resource status data 16 is set to "1" (H
(UNT) and the absolute address of the release condition matches the execution address, processing resource status data 1
The state flag 16a for the processing resource 6 is set to "2" (FREE).

Next, the processing resource data collection function 14
The e performs the following processing according to the processing resource status data 16. That is, the status flag 16a for the processing resource of the processing resource status data 16 is "1".
In the case of (HUNT), the program execution history collection function 14c refers to the program execution history data 18 under test based on the execution address to identify the program that captured the processing resource in the processing resource measurement data 17 (the capture program). Name) and capture request address,
A count flag for the processing resource of the resource holding counter 16b is set to "1" (ON), and a resource identification (RID) and a resource number (RNO) for identifying the processing resource are set.

When the count flag for the processing resource of the processing resource suspension counter 16b is "1" (ON), the counter corresponding to the processing resource of the processing resource suspension counter 16b is updated (1 is added).

The status flag 16a for the processing resource of the processing resource status data 16 is "2" (FREE).
In this case, the program execution history collection function 14c refers to the program execution history data 18 under test based on the execution address, and the processing resource measurement data 17 identifies the program that released the processing resource (released program name) and The release request address and the counter of the resource holding counter 16b are set, and the resource holding counter 1
The count flag of 6b is set to "0" (OFF).

After completion of the processing by the processing resource data collection function 14e, or the processing resource check function 1
When it is detected by 4d that the resource management flag 12 is non-registration "0", control is passed to the traveling control unit 19, and the traveling control unit 19 detects stop or end of the simulation process. Passes control to the command control unit 11 and ends the simulation process. When the stop or the end of the simulation processing is not detected, the simulation execution unit 14 is notified of this, and the above-described processing such as the reading of the next machine instruction by the operand read function 14a and the pseudo execution by the machine instruction pseudo function 14b is executed. repeat.

When the simulation process is completed,
The average instruction execution time is added to the number of holding steps for each processing resource set in the processing resource measurement data 17 to calculate the holding time required from capturing to releasing the processing resource, and based on this holding time ,
An appropriate number of processing resources is calculated according to a predetermined relational expression.

According to the present embodiment, the program to be measured is not manually analyzed on a desk, but the function of measuring processing resources is realized as an additional function of the program simulator, and the program to be measured may be modified or the like. , Instead of using a dedicated hardware monitoring device,
