compute-sanitizer-diagnose-cuda-bugs
Detect and diagnose CUDA correctness bugs with NVIDIA Compute Sanitizer. Routes GPU memory errors, shared-memory data races, uninitialized-memory reads, and synchronization/barrier bugs to the right sub-tool (memcheck, racecheck, initcheck, synccheck) and explains how to build, run, and read the report. Use when debugging illegal memory access, out-of-bounds, misaligned access, leaks, WAW/WAR/RAW races, __shared__ hazards, uninitialized reads, garbage results, hangs, divergent __syncthreads/__syncwarp, or cuda::barrier / wgmma issues. Do NOT use for host/CPU-side bugs (use valgrind or AddressSanitizer) or global-memory data races (out of scope). Trigger keywords - compute-sanitizer, memcheck, racecheck, initcheck, synccheck, CUDA memory error, OOB, race condition, uninitialized memory, __syncthreads, barrier, deadlock.

# Compute Sanitizer
## Purpose
NVIDIA Compute Sanitizer is a suite of four correctness tools for CUDA
(memcheck, racecheck, initcheck, synccheck). This skill is a **router**: pick
the right tool from the symptom below, then read the matching reference file for
its flags, output format, and caveats **before you run it**. Do not guess
flags — the details live in the reference.
**When to use:** finding and diagnosing GPU-side correctness bugs — illegal or
out-of-bounds memory access, misaligned access, leaks, shared-memory races,
uninitialized reads, and synchronization/barrier errors.
