Problems solved by technology

When using the TCP / IP protocol, the computer processor is required to process and calculate the data, which consumes a lot of CPU performance
Therefore, in actual use, low-end servers have fewer CPU cores and each core works at full load, which can basically guarantee the performance of HCA under the TCP / IP protocol. However, in high-end servers, there are as many as hundreds of processor cores, and More than 3T memory, when processing TCP / IP data, will lead to CPU multi-core calls and frequent memory calls, resulting in extremely low performance of HCA cards, which cannot meet practical applications

Embodiment Construction

[0034] Attached below Figure 1-2 , the HCA card performance testing method under a RHEL7.0 system of the present invention is described in detail below. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] as attached figure 1 As shown, the HCA card performance testing method under a RHEL7.0 system of the present invention, the implementation method is as follows:

[0036] S1. Prepare the Linux test platform, set up the test server and client, and communicate with each other through a communication protocol TCP / IP;

[0037] S2. Boot the test machine, install the Linux operating system on the test machine, and log in to the system with the root user;

[0038] S3. Copy the HCAtest.sh script and the iperf toolk...

Abstract

The invention provides an HCA card performance testing method under an RHEL7.0 system. The method comprises the steps that S1, a Linux test platform is prepared; S2, a Linux operating system is installed on a test machine; S3, an HCA test.sh script and an iper kit are copied onto the test machine; S4, a terminal program is run under the Linux system, and execution is performed under a Server and aClient; and S5, iper tools are executed to run an HCA card performance test, and in the testing process, a numact1 instruction is executed under a command execution window of the Server and a commandexecution window of the Client for optimization. According to the method, the test performance of HCA under the iper tools is automatically optimized through a Shell script; and compared with the traditional manual optimization mode, operation is convenient, and the situation that system crash is caused by an error of an associated register value which is manually modified is avoided.

Description

technical field [0001] The invention relates to the field of computer network testing, in particular to a method for testing the performance of an HCA card under a RHEL7.0 system. Background technique [0002] In the HCA card performance test, the RDMA protocol test method is generally used, and the TCP / IP protocol is rarely used for related performance tests. In actual use, the transmission network of the RDMA protocol is generally deployed, but in some practical applications, some customers still use the HCA card to deploy the network environment of the TCP / IP protocol in order to pursue higher bandwidth than the network card. The essence of the HCA card is It is designed and used based on the RDMA protocol, but also supports the TCP / IP protocol and can also be used as a network card. [0003] When the HCA card uses the RDMA protocol for data transmission, the data is directly transferred to the storage area of ​​the computer through the network, and the data is quickly m...
