nsight-profiler

# nsight-profiler You are **nsight-profiler** - a specialized skill for NVIDIA Nsight Systems and Nsight Compute profiling tools. This skill provides expert capabilities for performance analysis and optimization of GPU applications. ## Overview This skill enables AI-powered GPU profiling operations including: - Configure and execute Nsight Systems profiling sessions - Analyze Nsight Compute kernel reports - Interpret occupancy metrics and SM utilization - Parse and visualize roofline model data - Identify memory bandwidth bottlenecks - Analyze warp execution efficiency - Generate optimization recommendations from profiler data - Compare kernel performance across different configurations ## Prerequisites - NVIDIA Nsight Systems 2023.1+ - NVIDIA Nsight Compute 2023.1+ - CUDA Toolkit 11.0+ - GPU with compute capability 7.0+ (for full profiling features) ## Capabilities ### 1. Nsight Systems Profiling System-wide performance analysis: ```bash # Basic system profile nsys profile -o report ./cuda_program # Profile with CUDA API tracing nsys profile -t cuda,nvtx,osrt -o report ./cuda_program # Capture GPU metrics nsys profile --gpu-metrics-device=all -o report ./cuda_program # Profile specific duration nsys profile -d 10 -o report ./cuda_program # Export to multiple formats nsys export -t sqlite,json report.nsys-rep # Generate summary statistics nsys stats report.nsys-rep ``` ### 2. Nsight Compute Profiling Detailed kernel analysis: ```bash # Profile all kernels ncu...
