Ptx Isa Markdown

NVIDIA CUDA Documentation + Claude Code Skill

NVIDIA's PTX ISA 9.1, CUDA Runtime API 13.1, and CUDA Driver API 13.1 documentation converted to searchable markdown, with a Claude Code skill for GPU development.

What's Here

1. **PTX ISA 9.1 Documentation** (405 markdown files, 2.3MB)

   • Complete instruction set reference
   • All tables, code blocks, and mathematical notation preserved
   • Organized by chapter with section numbers
   • Images linked to NVIDIA's CDN

2. **CUDA Runtime API 13.1 Documentation** (107 markdown files, 0.9MB)

   • Complete function and data structure reference
   • 41 API modules (device, memory, streams, events, graphs, etc.)
   • 66 data structures (cudaDeviceProp, cudaMemcpy3DParms, etc.)
   • All parameters, return values, and detailed descriptions
   • Navigation, duplicate content, redundant URLs, and boilerplate removed (83% size reduction)

3. **CUDA Driver API 13.1 Documentation** (128 markdown files, 0.8MB)

   • Complete low-level driver API reference
   • 50 API modules (context, module loading, virtual memory, graphs, etc.)
   • 80 data structures (CUdevice, CUcontext, launch parameters, etc.)
   • All parameters, return values, and detailed descriptions
   • Navigation, duplicate TOC, cross-references, and redundant URLs removed (76% size reduction)

4. **CUDA Development Skill** for Claude Code

   • PTX instruction lookup and examples
   • CUDA Runtime & Driver API function reference
   • Profiling workflows (nsys, ncu)
   • Debugging patterns (compute-sanitizer, cuda-gdb)
   • TensorCore operation reference (WMMA, WGMMA, TMA)

Why

NVIDIA's official documentation is:

• PTX ISA: A single 5MB HTML page requiring Ctrl+F through megabytes
• CUDA Runtime API: 75+ separate HTML pages requiring multiple clicks
• CUDA Driver API: 130+ separate HTML pages requiring multiple clicks

This conversion enables:

• grep -r "register fragment" ptx-docs/ instead of Ctrl+F
• `grep -r "cudaErrorInvalidValue" cuda-runti
