Embodiment Construction

[0022] The content of the present invention is described in more detail below:

[0023] The whole process mainly uses the shell script to realize the calculation of the theoretical memory bandwidth. According to the number of memory channels supported by the input single CPU, the script automatically exchanges the current frequency of the memory and the total number of memory channels, and then calculates the theoretical bandwidth of the memory, eliminating the need for human-computer interaction. .

[0024] The script mainly completes the following functions:

[0025] (1) Manually enter the number of memory channels under a single cpu

[0026] Run the automated test script through the command terminal. The terminal will prompt as follows. Manually enter the number of memory channels under a single CPU, and the script will read the data to prepare for subsequent calculations.

[0027] Please input the numbers of memory channels per cpu:

[0028] (2) The script automatically...

Abstract

The present invention provides a method for automatically calculating theoretical memory bandwidth in a linux system, and relates to server system testing technologies. Calculation of the theoretical memory bandwidth is implemented by using a shell script, only a quantity of channels of a memory of a single CPU is manually input, and the script automatically acquires a total quantity of channels of the memory and a current frequency of the memory. The theoretical bandwidth is calculated, and a result is displayed to a screen. It is unnecessary to manually input another system command or perform another operation. The script is convenient in use and simple in operation, and an operation can be completed without professional knowledge. The method is applied to a memory test in a server system testing phase, manpower and time can be saved, and work efficiency is improved.

Description

technical field [0001] The invention relates to server system testing technology, in particular to a method for automatically calculating memory theoretical bandwidth under a linux system. Background technique [0002] An important test in the server system test is the memory performance test. In the test, continuous tuning is required to maximize the memory performance, and then compared with the theoretical bandwidth of the memory to determine whether the memory performance of the server meets the requirements. Calculating the theoretical bandwidth of memory is also complicated for those without relevant experience. Contents of the invention [0003] In order to solve this problem, this paper proposes a method for automatically calculating the theoretical memory bandwidth under the Linux system. The calculation of the theoretical memory bandwidth is realized based on shell scripts under the Linux system, which reduces the time for checking the machine configuration, the ...
