Thanks Daniel, do you mean that I can use CUDA through the cuSPARSE wrappers for having the matrix and vectors on the GPU (and then implement GMRES by myself) or is it still possible to use Trilinos solvers having it running automagically on GPU? Please forgive me if this is a dumb question. As I already mentioned I am not familiar neither with deal.II nor with Trilinos... Thanks again and best regards, Massimo
