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
Debugging is started in an interactive session by running:
compute-sanitizer --tool <tool> ./cuda_program
<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
