You observe high latency and low bandwidth between two GPUs connected via an NVLink switch. You suspect a problem with the NVLink link itself.
Which of the following methods would be the most effective in diagnosing the physical NVLink link health?
- A . Using ‘iperf3’ to measure network throughput between the servers.
- B . Running a CUDA-aware memory bandwidth test specifically designed for NVLink.
- C . Examining system logs for NVLink-related error messages.
- D . Using ‘ping’ to check network connectivity between the servers.
- E . Physically inspecting the NVLink cables for damage.
B,C,E
Explanation:
A CUDA-aware memory bandwidth test can specifically measure the NVLink link’s performance. System logs can reveal hardware- level errors. Physical inspection can identify damaged cables. ‘iperf3’ and ‘pings are network-level tools and don’t directly test the NVLink link. Checking for error messages in System Logs also helps identify potential issues related to the NVLink switch and the link connections.
