NVIDIA Base Command Manager (BCM) is the designated software for managing and monitoring DGX SuperPOD clusters. Its Base View dashboard is specifically designed to provide a centralized, real-time, graphical overview of key performance metrics across all nodes. This includes GPU utilization, GPU memory, CPU usage, and system memory. Using this dashboard is the most effective and efficient method for identifying system-wide performance bottlenecks, such as those caused by GPU resource contention, without needing to manually access individual nodes.

A. Checking Slurm logs is useful for diagnosing job scheduling or resource allocation errors, but it does not provide real-time utilization metrics for active hardware.

C. The top command monitors CPU and memory usage but provides no information about GPU utilization, which is a critical component in a DGX cluster.

D. Using nvidia-smi on each node is a valid way to check GPU status, but it is highly inefficient and not scalable for a multi-node SuperPOD cluster.

1. NVIDIA Base Command Manager User Guide (v3.2.0): In Chapter 3, "Dashboards," the "Base View" section describes this dashboard as the primary tool for a "high-level overview of the cluster, including GPU, CPU, and memory utilization... essential for quickly identifying system-wide performance bottlenecks."

2. NVIDIA DGX SuperPOD Reference Architecture: The "Management and Monitoring" section details the software stack, emphasizing that NVIDIA Base Command Manager provides the unified, cluster-wide monitoring capabilities necessary for operating the system. It highlights the dashboards for visualizing aggregate system health and performance.
