Can one of the admins verify this patch?

Thanks @pcanal ! I did practically the same but did not work for me. I'll try it tomorrow.

Thanks. All those are necessary and the derived code also needs to use the cuda_rdc_ (or be willing to jungle with sharp knifes and hope for the best :) ). Any errors would indicates that we either missed a spot or (hopefully not) that there is still issue to be solved in CudaRdcUtils
