NCP-AII Question 44
Select 4You are tasked with installing and configuring an NVIDIA NVLink™ Switch to enable high-speed communication between multiple NVIDIA GPUs in a data center. During the setup, you aim to maximize bandwidth and ensure proper connectivity. Which of the following steps are required for a successful installation and configuration of the NVLink Switch?
- A
Ensure that all GPUs are NVLink-compatible and connected to the switch using NVLink bridges.
- B
Update the system BIOS and firmware to support NVLink Switch configurations.
- C
Manually configure NVLink bandwidth settings in the NVIDIA Control Panel.
- D
Verify NVLink topology using the NVIDIA System Management Interface (nvidia-smi).
- E
Install the NVIDIA NVSwitch driver as part of the GPU driver installation process.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
Installing and configuring an NVIDIA NVLink Switch involves ensuring hardware compatibility, updating firmware, verifying connectivity, and installing the appropriate drivers. NVLink topology must be checked using the NVIDIA System Management Interface (nvidia-smi) to confirm proper functionality. However, manual bandwidth configuration in the NVIDIA Control Panel is not required, as NVLink automatically manages bandwidth allocation.
- A. Correct.
Correct: All GPUs involved must support NVLink and be physically connected to the NVLink Switch via NVLink bridges. This is a prerequisite for communication through the NVLink Switch.
- B. Correct.
Correct: Updating the system BIOS and firmware ensures compatibility with the NVLink Switch and prevents software issues during operation.
- C. Incorrect.
Incorrect: NVLink bandwidth settings are automatically managed by the drivers and hardware; manual configuration via the NVIDIA Control Panel is not required.
- D. Correct.
Correct: Verifying NVLink topology using nvidia-smi helps confirm that the NVLink Switch and GPUs are properly recognized and set up in the system.
- E. Correct.
Correct: The NVIDIA NVSwitch driver is included as part of the GPU driver package and is necessary for enabling NVLink Switch functionality.
