Description

Description: TECHNICAL FIELD The present invention relates to a method capable of evaluating the hardware performance of all processors in a processor complex system with one instruction.

[Conventional technology]

Conventionally, when evaluating the performance of a computer system, the work of evaluating the hardware performance and software performance of the system was performed separately. In that case, performance data was collected independently for each processor, even for a multi-processor configuration Was. Therefore, the operation becomes extremely complicated, and it is difficult to synchronize and acquire performance data of hardware and software.

As a system performance evaluation method using a conventional hardware monitor, for example, “HITAC-OEM Export CUP Manual (L9-EXP-SD-014)“ Hardware Monitor
Driver Program Description (HARDWARE
MONITOR PROGRAM DISCRIPTION "].
According to this, since control is independently performed for each processor implemented in the hardware monitor, performance data is collected from the hardware monitor in this control unit, and the data is collected. It only output in its original form. In other words, the hardware monitor implemented in each processor cannot be controlled in an integrated form as a processor complex (a complex of processors). Therefore, data collected from the hardware monitor, analysis, evaluation, and software・ Synchronous control with the monitor was not processed.

[Problems to be solved by the invention]

As described above, in the conventional performance evaluation method, no consideration was given to performing a simple operation for performance evaluation under the actual operation of the system. Therefore, the performance evaluator required the physical configuration of the processor complex and the performance to be obtained. It was necessary to input parameters over many items, such as the type of. As a result of the need for such complex operations, it is virtually impossible to evaluate the performance of a running system.

Conventionally, no consideration has been given to synchronizing a hardware monitor and a software monitor to collect and merge data from both monitors, and to analyze and evaluate collected data. So
Timely implementation of synchronous measurement, analysis and evaluation of hardware performance and software performance was not possible.

Further, conventionally, no consideration has been given to the security (security) of performance data, and thus there has been a problem with respect to data integrity.

Acceleration of computer systems is achieved through technological innovations in both hardware and software.In performance evaluation, hardware performance data and software performance data are synchronized by measurement under actual system operation. It is desirable that the data can be collected and implemented by simple external operations including analysis and evaluation.

An object of the present invention is to solve such a conventional problem, complete a system performance evaluation combining hardware performance and software performance under actual operation of the system with one measurement, and obtain the obtained performance data. An object of the present invention is to provide a method for evaluating system performance that can provide security.

[Means for solving the problem]

In order to achieve the above object, a method for evaluating system performance according to the present invention comprises the steps of:
Select the time specified by the timer, the measurement interval, or the job to be measured, start the hardware monitor and the software monitor in synchronization, execute the performance measurement of each operation, and stop in synchronization Then, by collecting the measured data and merging the performance data of both monitors, the performance data is analyzed and evaluated in comparison with the past database stored in advance, and the data after the evaluation is analyzed by human. After converting the data into a code that can be recognized and storing it in the result file, the data is checked for access authority with a password and read.

[Action]

In the present invention, a single instruction code is
It controls all hardware performance data of all processors that make up the complex, and also manages various times and times, such as activation and termination of hardware monitors and software monitors, and data collection. In addition, in order to analyze and evaluate the collected performance data,
By accumulating and managing the target performance database and the performance database collected during past measurements,
It enables comparison and verification of performance data. Furthermore, for security management of collected, analyzed and evaluated gender data, access authority is enabled by password management according to the reference permission range. These operations enable execution of a series of processing sequences by a minimum of two external operations for simplicity.

First, when the performance evaluation system is started by an external operation (step 1001), the operator is prompted to input an operation designation (step 1002). There are two types, the parameter method specification and the manual method specification. If the parameter method is specified now, the external storage device
The parameter data is read from the file 1211 of the 1201 into the data area 1101 (step 1003). If the manual method is specified, parameter data is created in the form of an inquiry with the operator and set in the data area 1101 (step 1004). Parameter
The contents of the data are three items: a "measurement start / end method", a "software monitor name" for performing measurement in synchronization, and a "password" meaning an access right to the result data. The following processing is performed in accordance with the type of the measurement start / end method, each time start / end by timer designation, start / end in manual mode, and start / end by job name designation are specified. The processing is executed.

First, in the case of start / end by specifying the timer, both the hardware monitor and the software monitor are started simultaneously at the set start time (step 1005), and both monitors are stopped at the end time, and the performance data is saved. Data area 1102
Expand on top. In the case of start / end in the manual mode, start of measurement (step 1008), end of measurement, and development of performance data on the data area 1102 (step 1010).
Is executed in response to an external operation. When starting / ending by specifying the timer and starting / ending in the manual mode, the processing of steps 1006 and 1009 enclosed by a broken line is an optional processing. (The specification is step 1003
1004), the performance data is developed in the data area 1102 at each interval.

In the case of start / end by job name specification, start the hardware monitor and software monitor, start the specified job (step 1011), stop both monitors after the job ends, and perform performance data The data area 1102

Data collection from the hardware monitor 1401 is performed by one instruction code regardless of the number of processors.

The processing up to this point is the measurement and data collection processing, and subsequently, the analysis and evaluation processing of the collected data is performed in the following order.

First, the target performance data 1212 and the past performance data 1213 are read into the data area 1103. And
A comparison process is performed with the currently measured data temporarily stored in the data area 1102 to analyze and evaluate the problem (steps 1013 and 1014). Finally, data area 1102
The performance data is stored and output to a file 1214. at the same time,
The permission level is identified by checking the password access authority (step 1015), and the performance result data within the permitted range is converted into a code that can be recognized by the human eye from the data area 1102, and the analysis and evaluation data from the data area 1103. The data is converted and output to the output device 1302.
