Embodiment 1

[0025] The verification method steps are as follows:

[0026] 1) Build a test platform, prepare the test environment, install the Red Hat system, and install the Python language;

[0027] 2) Set environment variables;

[0028] 3) Set the number of runs;

[0029] 4) Configure the test parameter file;

[0030] 5) Delete the process test result file;

[0031] 6) Obtain hardware information;

[0032] 7) Start the test, and each thread performs Copy, Scale, Add, and Triad operations on a part of the memory;

[0033] The Copy operation is: first access a memory unit to read the value, and then write the value to another memory unit; the Scale operation is: first read the value from the memory unit, perform a multiplication operation, and then write the result to to another memory unit; the Add operation is: first read two values ​​from the memory unit, perform an addition operation, and then write the result to another memory unit; the Add operation is: first read two values ​​...

Abstract

The invention discloses a verification method for memory bandwidth and pressure gradual-change parallelism. The method comprises the steps that setting up a testing platform, and preparing testing environment; setting environmental variables; setting running frequency; configuring a testing parameter file; deleting a process testing result file; obtaining hardware information; starting testing, wherein each thread conducts Copy, Scale, Add, Triad operation on a part of memory; monitoring the testing process; repeatedly conducting verification when abnormities appear in the testing process; collecting the testing result, judging that the test fails when the complete testing running is finished, no abnormities exist in a system, and the Triad value does not meet 70% of the theoretical value, and adjusting and optimizing the system for continuous testing; achieving the performance stability testing effect and judging that the test passes when the complete testing running is finished, no abnormities exist in the system, and the Triad value meets 70% of the theoretical value. The verification method has the advantages of being easy to operate, higher in practicability and the like, effectively ensures the stability of a server, and is quite effective for verifying the product quality.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to a parallel verification method for memory bandwidth and pressure gradients. Background technique [0002] With the development of society, computer servers have been applied to various fields, especially the Internet, finance and other fields, and the use of servers has become complex and diverse. This causes various problems on the server. For example, in the application of a certain server, there are frequent major failures such as error reporting and restarting. This is an unacceptable serious quality problem. Therefore, whether the server is in the R&D stage or the subsequent product maintenance stage, it is necessary to conduct a comprehensive system stress test on the product to ensure the stability of the product. [0003] A very important part of server motherboard design is the power supply part of the motherboard. Although the POWER test team will have a compl...
