Debugs CUDA kernel errors using compute-sanitizer (memcheck, racecheck, initcheck, synccheck), cuda-gdb (non-interactive batch backtrace), and cuobjdump (PTX/SASS/register analysis). Use when a CUDA kernel crashes (segfault, illegal memory access), produces wrong results, hangs, or when the user asks to debug or…
CUDA kernel development, debugging, performance optimization, linear algebra, and multi-GPU communication for Claude Code. Use when writing, debugging, or optimizing CUDA code, GPU kernels, parallel algorithms, or CUDA library calls. Covers cuBLAS/cuBLASLt GEMM operations, CUDA Math API (half, bfloat16, FP8, FP6…
Curated index of NVIDIA official CUDA Samples with code patterns, GitHub permalinks, and key snippets. Use when looking for working CUDA code examples, GPU kernel patterns (reduction, scan, GEMM, transpose, histogram), Tensor Core WMMA usage, CUDA Graphs API, cuBLAS/cuFFT/cuSPARSE library integration, stream/event…
