@ChaamC Using the CWL extensions loaded with this PR's changes, you should be able to provide cwltool:CUDARequirement directly in the requirements (if CUDA is indeed required for your app). If it can run in CPU-only mode, only then it should be set in hints, allowing the tool to ignore unfulfilled requirement by some machine/server running the app.
