CUDA-MEMCHECK The CUDA-MEMCHECK category is closed, please use the Compute-Sanitizer forum. Compute Sanitizer 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: CUDA-GDB CUDA-GDB allows you to debug both the CPU and GPU portions of your application simultaneously.
