A system administrator needs to collect the information below: GPU behavior monitoring GPU configuration management GPU policy oversight GPU health…

NVIDIA Data Center GPU Manager (DCGM) is the single, comprehensive suite of tools designed for managing and monitoring NVIDIA GPUs in large-scale cluster environments. It provides a unified API for all the required tasks listed: active health monitoring and diagnostics, system validation, policy management (e.g., for handling errors), power and clock configuration, detailed accounting statistics for processes, and monitoring of NVSwitch and NVLink interconnects. It is specifically engineered for the enterprise-level oversight described in the question.

A. nvidia-smi: This is a command-line utility for basic, real-time monitoring and management but lacks the advanced, scalable features of DCGM, such as comprehensive diagnostics, policy management, and long-term accounting.

B. CUDA Toolkit: This is a parallel computing platform and programming model for developers. It includes compilers and libraries for building applications, not for enterprise-level infrastructure management and monitoring.

D. Nsight Systems: This is a performance analysis tool for developers to visualize and optimize application performance across CPUs and GPUs. It is not intended for system administration, health diagnostics, or policy enforcement.

1. NVIDIA DCGM User Guide (v3.3.4), Chapter 1. Introduction: "DCGM is a suite of tools for managing and monitoring NVIDIA GPUs in cluster environments. It includes active health monitoring, diagnostics, system validation, policies, power and clock management, group configuration, and accounting." This section explicitly lists the capabilities mentioned in the question, including NVSwitch monitoring.

2. NVIDIA DCGM User Guide (v3.3.4), Section 1.1. Key Capabilities: This section details the features, confirming DCGM's role in "GPU Health and Diagnostics," "GPU Configuration Management," "GPU Policy Management," "Process and Accounting Statistics," and "NVSwitch Monitoring."

3. NVIDIA Developer Blog, "Introduction to the NVIDIA Data Center GPU Manager (DCGM)" (2021): The article states, "DCGM is a low-overhead tool that performs a multitude of functions on each GPU in a data center, such as active health monitoring, diagnostics, system validation, policies, power and clock management, configuration management, and accounting." This reinforces that DCGM is the single tool for this wide range of administrative tasks.
