cuassert

cuassert is a C++ assertion library designed for use with CUDA. It provides macros similar to the standard C++ assert macro, but with extensions to work within the CUDA execution model, including both host and device code. The primary purpose of cuassert is to help developers detect and diagnose errors during the execution of CUDA kernels and host code that interacts with the GPU.

The library offers macros such as cuassert() and cuassert_msg() which can be invoked from within CUDA kernels running on the GPU. When an assertion fails, cuassert typically logs an error message that includes the file name, line number, and the failed condition. It also provides information about the CUDA device and thread block where the failure occurred, which is crucial for debugging parallel code.

cuassert aims to simplify the process of identifying issues in CUDA applications by providing a consistent and familiar assertion mechanism. Its integration allows developers to easily incorporate checks for expected conditions directly within their CUDA kernels, improving the robustness and reliability of GPU-accelerated software. The library is designed to be lightweight and not introduce significant overhead when assertions are not triggered.
