About the Compute Sanitizer category

Compute Sanitizer is a functional correctness checking suite included in the CUDA toolkit.This suite contains multiple tools that can perform different type of checks:

  • The memcheck tool is capable of precisely detecting and attributing out of bounds and misaligned memory access errors in CUDA applications. The tool can also report hardware exceptions encountered by the GPU.
  • The racecheck tool can report shared memory data access hazards that can cause data races.
  • The initcheck tool can report cases where the GPU performs uninitialized accesses to global memory.
  • The synccheck tool can report cases where the application is attempting invalid usages of synchronization primitives.

In addition, the Compute Sanitizer API enables the creation of code analysis and sanitization tools that targets CUDA applications
