NCP-AII Question 45
Select 3You are tasked with configuring an NVIDIA NVLink™ Switch for a data center AI workload, aiming to maximize GPU interconnect bandwidth and ensure proper connectivity for a cluster of 8 NVIDIA GPUs. Which of the following steps must you perform during the installation and configuration process?
- A
Verify that the GPUs in the system are NVLink-compatible and supported by the NVLink Switch topology.
- B
Ensure the system BIOS is updated to the latest version that supports NVLink Switch configurations.
- C
Manually configure the NVLink Switch topology using the NVIDIA Management Library (NVML) commands.
- D
Install the appropriate NVIDIA drivers that include NVLink Switch support and verify their compatibility with the operating system.
- E
Ensure the NVLink Switch is connected to an external network switch to enable broader cluster communication.
Show answer and explanation
Correct answers: A, B, D
Explanation
The NVIDIA NVLink™ Switch provides high-bandwidth, low-latency interconnects between GPUs in a cluster. To install and configure it correctly, you must ensure that the GPUs are compatible, update the system BIOS to support the hardware, and install the appropriate NVIDIA drivers. Manual configuration is generally unnecessary, and external network switches are not required for NVLink connectivity as it is an internal interconnect. By following these steps, you can maximize GPU communication efficiency for AI workloads.
- A. Correct.
Correct. To properly utilize NVLink Switch, the GPUs must be NVLink-compatible and supported by the specific topology being implemented. This is a prerequisite for installation.
- B. Correct.
Correct. Updating the system BIOS ensures that the hardware and firmware can fully support NVLink Switch configurations, which is critical for proper operation.
- C. Incorrect.
Incorrect. NVLink Switch topology is typically auto-configured at the hardware level when supported GPUs and drivers are installed. Manual configuration using NVML is not required in most cases.
- D. Correct.
Correct. Installing the correct NVIDIA drivers ensures that NVLink Switch functionality is enabled and supported by the software stack, which is essential for performance and stability.
- E. Incorrect.
Incorrect. The NVLink Switch does not require a connection to an external network switch for GPU-to-GPU communication within the cluster. NVLink is an internal high-bandwidth interconnect specifically designed for this purpose.
