Problems solved by technology

[0002] In the Mellanox performance test, the official Mellanox driver is generally used. By manually installing the driver and using the related tools of the Linux system, it is possible to test the bandwidth of the HCA card on each model. Each test needs to configure environment variables and other related complex tasks. , and cannot implement automated testing

Embodiment Construction

[0021] The content of the present invention is described in more detail below:

[0022] Test steps:

[0023] 1. Prepare the Linux test platform (including testing the server side, client side and installing the Linux operating system on the test machine);

[0024] 2. Start the test machine, install the operating system, and log in to the system as the root user;

[0025] 3. Copy the BWtest script and the system HCA driver package to the system desktop;

[0026] 4. Run the terminal program under the Linux system, execute ib_read_bw and ib_write_bw on the server side, and execute . / BWtest on the client side. The default test is 10 times, and the average value is calculated. The client-side terminal will display the bandwidth obtained by the test tool value.

[0027] 5. At this time, a log.txt file recording time will appear in the / root / Desktop / result folder;

[0028] 6. If you need to test the HCA card reading and writing stress test for a long time, you can modify the scri...

Abstract

The invention provides a time delay method for automatically testing HCA (Host Channel Adapter) card bandwidth through a RDMA (Remote Direct Memory Access) way, and belongs to the field of Mellanox performance testing. On the basis of a shell script under Linux, the bandwidth of the HCA card under a Linux system can be quickly configured and tested, and the RDMA way is adopted for testing. The testing method is relatively simple, automatic testing can be realized, and time and manpower cost can be saved.

Description

technical field [0001] The invention relates to Mellanox performance testing technology, in particular to a method for automatically testing HCA card bandwidth and delay through RDMA. Background technique [0002] In the Mellanox performance test, the official Mellanox driver is generally used. By manually installing the driver and using the related tools of the Linux system, it is possible to test the bandwidth of the HCA card on each model. Each test needs to configure environment variables and other related complex tasks. , and cannot implement automated testing. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a method for automatically testing HCA card bandwidth and delay by means of RDMA. The HCA card bandwidth test is performed through RDMA, the test method is relatively simple, and it can realize automated testing, saving time and labor costs [0004] The technical scheme of the present invention is...
