Testing Long-Term Stability Performance

4.4.1

To test the device long-term stability performance.

See the test networking diagram.

1. The power supply of the server is normal.
2. The device uses a stable commercial BIOS version.
3. The Linux OS and required drivers have been installed.
4. No other services are running.
5. A CPU stress test software, such as stress, has been installed on the device. For details about how to compile and install the software, see the tool description.

1. Add environment variables.

   Log in to the server as the root user and run the vi ~/.bashrc command to configure environment variables. For details, see the MindX Toolbox User Guide.

2. Run the CPU test software, for example, stress.

   stress --cpu {Number of CPU cores}

   Note: You can run the following command to query the number of CPU cores:

   # cat /proc/cpuinfo| grep "processor"| wc -l

3. Open a new window and run the following command to increase the NPU usage:

   ascend-dmi -p -dur 43200 -it 5 -pm refresh

4. Stop the CPU test software when the test is complete.

The OS is operating properly, and no error logs are generated.

For details about how to use the Ascend-DMI tool, see Test Tools.
