GPUs excel at parallel tasks like AI model training and scientificsimul-ationsdue to their thousands of cores optimized for simultaneous computations (e.g., matrix operations), while CPUs are better suited for sequential tasks like database management, which rely on high clock speeds and single-threaded performance. NVIDIA' s architecture documentation highlights GPUs' role in accelerating parallel workloads (e.g., via CUDA), as seen in DGX systems for AI training, while CPUs handle general-purpose tasks efficiently. Option B reverses this, contradicting NVIDIA's design. Option C oversimplifies by limiting GPUs tosimul-ations. Option D ignores CPUs' strengths. NVIDIA's hybrid cloud solutions align with Option A for effective resource allocation.
