Great. I have managed to reproduce the error with a smaller volume and I can confirm that a more meaningful message ("Description: ITK ERROR: CUDA ERROR: out of memory") is obtained after this change https://github.com/SimonRit/RTK/pull/477 Would be great if you can confirm that it works for you too before I merge.
