Chih-Che, The CUDA support in deal.II is very new. It is only in the development version of deal (https://github.com/dealii/dealii). You can see our current development plan here https://github.com/dealii/dealii/projects/2 Right now, we have support for vector and partial support for matrix-free (a good place to see the capabilities is the test suite https://github.com/dealii/dealii/tree/master/tests/cuda). I would advise you to wait for this PR https://github.com/dealii/dealii/pull/4846 to be merged before your try to install deal with CUDA. This PR makes it a lot easier to install deal with CUDA. If you want to work on CUDA, you should work on something that you like / is of interest to you. If you want to help our existing effort, you can pick something from this list https://github.com/dealii/dealii/issues/4399. I am working on the first item but let me know if you find anything else interesting, I can help you implementing it.
If you have any questions, please ask. We are looking for people to help us with CUDA.
