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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. **When NOT to use:** host/CPU-side bugs (use valgrind or AddressSanitizer), pure functional/logic bugs unrelated to memory or races, or **global-memory** data races (out of scope — use iGUARD or SuperCollider). ## Prerequisites - A CUDA Toolkit installation that provides both `nvcc` and `compute-sanitizer` on `PATH`. - A CUDA-capable GPU visible to the process. - Build with `nvcc -lineinfo` for source attribution (add `-Xcompiler -rdynamic` for host backtraces). ## Inputs | Input | Required? | Where it comes from | |---|---|---| …

How to install
mdr add nvidia/skills/compute-sanitizer-diagnose-cuda-bugs@sha256:0253adc748efd115The line at the top of this page pins the label git:20261019.8a74306, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
