NVIDIA Nsight Systems and NVIDIA Nsight Compute are specialized profiling tools designed to analyze the performance of GPU- accelerated applications. They provide detailed insights into kernel execution, memory access patterns, and other performance-critical aspects. 'nvidia-smi' provides basic GPU stats but not application-specific profiling. CPU/memory utilization (A, D) and application logs (B) are helpful but don't provide the necessary GPU-specific information. You may have to install it into the container's image.

Option C is the most flexible and efficient approach. By tailoring MIG instance sizes to each application's specific needs, you can ensure that resources are allocated efficiently, and the overall performance is optimized. Other options may not fully utilize the GPU or may lead to resource contention.

Node Affinity allows you to specify rules for scheduling pods onto specific nodes based on labels or other node properties. In this case, you would use node affinity to target nodes with the 'nvidia.com/gpu' label.

Object storage systems, especially those optimized for metadata management, are well-suited for storing and accessing large numbers of small files. Parallel file systems are also designed for high IOPS and low latency, making them efficient for handling numerous small file operations. Traditional block storage with a large block size can lead to wasted space. NAS over NFS can become a bottleneck. Tape is unsuitable for frequently accessing data.

BCM relies on DCGM to collect GPU metrics. If DCGM is not properly configured or running, BCM will not be able to retrieve the necessary data to display GPU metrics. While the other options could potentially cause issues, a misconfigured DCGM is the most common reason for this specific symptom.
