During November 2024, this developer integrated CUDA toolkit support for CUSOLVER within the trilinos/Trilinos repository, focusing on enhancing the build system’s robustness and maintainability. Leveraging CMake and its find_package(CUDAToolkit) functionality, they refactored the CUDA/CUSOLVER workflow to streamline detection and integration of CUDA components. By adopting the CUDA::cusolver target, the build process now offers improved portability and reduces manual configuration, supporting easier developer onboarding and more reliable continuous integration. Their work centered on build system engineering and CMake scripting, resulting in a more maintainable and portable solution for delivering CUDA-enabled features across diverse development environments.
