compute-sanitizer: functional correctness checking suite for CUDA programs


Puhti: 2020.2.0
Mahti: 2020.3.1


compute-sanitizer is a functional correctness checking suite included in the CUDA toolkit (starting from version 11). In order to use the tool, the CUDA code has to be compiled with the extra flags -g and -G.

Debugging is started in an interactive session by running:

compute-sanitizer  --tool <tool> ./cuda_program
where <tool> is one of the several sub-tools for different type of checks:

  • memcheck: is capable of precisely detecting and attributing out of bounds and misaligned memory access errors in CUDA applications. It can also report hardware exceptions encountered by the GPU (default)

  • racecheck: can report shared memory data access hazards that can cause data races.

  • initcheck: can report cases where the GPU performs uninitialized accesses to global memory

  • synccheck: can report cases where the application is attempting invalid usages of synchronization primitives
