AI Analysis
●●SolidBig Brain
Production-ready CUDA profiling when NSight only works in development.
Strengths
- •Hardware-level PC sampling at 2k samples/sec with minimal overhead.
- •Integrates with existing Parca backend and MCP support for LLM analysis.
- •Configurable sampling factor (2^5 to 2^31) balances detail vs. performance.
Weaknesses
- •Requires CUDA_INJECTION64_PATH shim, adding deployment complexity.
- •Maxwell architecture or newer only, excludes older GPU hardware.
