Ray Tracing Cores, introduced in NVIDIA’s RTX architecture, are specialized hardware units built to accelerate ray-tracing computations—simulating light interactions (e.g., reflections, shadows) for photorealistic rendering in real time. CUDA Cores handle general-purpose parallel tasks, and Tensor Cores optimize matrix operations for AI, but only Ray Tracing Cores target lighting simulation.

An NVIDIA Certified Server with RTX GPUs is optimized for real-time collaboration and rendering, supporting NVIDIA Virtual Workstation (vWS) software. This setup enables low-latency, multi-user graphics workloads, ideal for team-based design or visualization. T4 GPUs focus on inference efficiency, and DGX SuperPOD targets large-scale AI training, not collaborative rendering.

The surge in AI adoption is driven by two key enablers: high-powered GPUs and large amounts of data. High-powered GPUs provide the massive parallel compute capabilities necessary to train complex AI models, particularly deep neural networks, by processing numerous operations simultaneously, significantly reducing training times. Simultaneously, the availability of large datasets—spanning text, images, and other modalities—provides the raw material that modern AI algorithms, especially data-hungry deep learning models, require to learn patterns and make accurate predictions. While Moore’s Law (the doubling of transistor counts) has historically aided computing, its impact has slowed, and rule-based machine learning has largely been supplanted by data-driven approaches.

Kubernetes excels in container orchestration with advanced scheduling (assigning workloads based on resource needs and availability) and load balancing (distributing traffic across pods via Services). It’s not inherently bare-metal (it runs on various platforms), and inferencing capability depends on applications, not Kubernetes itself, making B and D the true statements.

NVIDIA Data Center GPU Manager (DCGM) aids data center monitoring and management by providing detailed GPU telemetry, health diagnostics, and performance tracking at scale. Clara targets healthcare, TensorRT optimizes inference, and Mellanox Insight isn’t a standard NVIDIA tool, making DCGM the go-to solution.

Artificial Intelligence (AI) is the overarching field encompassing techniques to mimic human intelligence. Machine Learning (ML), a subset of AI, involves algorithms that learn from data. Deep Learning (DL), a specialized subset of ML, uses neural networks with many layers to tackle complex tasks. This hierarchical relationship—DL within ML, ML within AI—is the correct differentiation, unlike the reversed or conflated options.

OpenSM (Open Subnet Manager) is essential for InfiniBand networks, managing the fabric by discovering topology, configuring switches and host channel adapters (HCAs), and handling routing. Without it, the fabric cannot operate. Verbs is an API for RDMA, and MPI is a communication protocol, but OpenSM is the critical software component for functionality.

NVIDIA vGPU (Virtual GPU) software enables GPU virtualization by partitioning a physical GPU into multiple virtual instances, assignable to virtual machines or containers for accelerated workloads. Horizon is a VMware product, and “virtGPU” isn’t an NVIDIA offering, confirming vGPU as the correct solution.

Multi-node training is advantageous when a model’s size—its parameters, activations, and gradients—exceeds the memory capacity of a single GPU. By sharding the model across multiple nodes (using techniques like data parallelism or model parallelism), training becomes feasible and efficient. User count and inference scale are unrelated to training architecture needs, which focus on compute and memory distribution.

The nvidia-smi (System Management Interface) command is the primary tool for checking GPU utilization on NVIDIA systems, including the DGX H100. It provides real-time metrics like utilization percentage, memory usage, and power draw. NVML (NVIDIA Management Library) is an API, not a command, and ctop is unrelated, solidifying nvidia-smi as the standard.
