Your data center's utility bills are through the roof, and your operations manager wants a centralized solution to monitor real-time power draw and enforce strict wattage caps across all your GPU-accelerated server nodes. Which NVIDIA tool is designed to manage power telemetry and set device-level power limits across an entire cluster scale?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Alright, check this out. When you're running a massive cluster, power bills can get crazy real quick, and you need a way to keep things under control without losing your mind. While nvidia-smi is great when you're logged into a single host checking a local GPU, it doesn't scale to a whole data center. That's where NVIDIA Data Center GPU Manager—or DCGM—comes into play. It gives you the big-picture view, letting you track power telemetry across your entire cluster and set hard limits on how many watts a GPU can pull. Trust me, if you try to manage an entire room of DGX systems using local command-line tools, your operations team will be looking for a new engineer. DCGM is the tool that makes cluster-level power capping clean and automated.

Full Explanation
NVIDIA Data Center GPU Manager (DCGM) is a suite of tools designed to manage and monitor NVIDIA GPUs in large-scale cluster environments. One of its key features is power management, which allows administrators to monitor real-time power consumption and enforce power limits (capping) at the GPU level across the entire cluster. This is crucial for optimizing energy efficiency, staying within data center power budgets, and preventing thermal throttling. - DCGM (the correct answer) is specifically built for cluster-wide management, providing APIs and integration with orchestration tools like Kubernetes to collect telemetry and apply configurations. - nvidia-smi (Option A) is a command-line tool intended for monitoring and managing local GPUs on a single host. It is not designed for cluster-wide or data center-level telemetry aggregation and policy enforcement. - NVIDIA Virtual GPU (vGPU) Software (Option B) is virtualization software that allows multiple virtual machines to share physical GPU resources. It does not handle cluster-level power management. - There is no tool called NVIDIA DGX System Daemon (dgxd) (Option D) designed for cluster power limit enforcement; this is a distractor.
