Elmira, Kokkos is at the moment only used directly for the Portable MatrixFree implementation and the LinearAlgebra::distributed::Vector (with MemorySpace=MemorySpace::Default). However, all of Trilinos relies implicitly on Kokkos and the Tpetra classes, in particular, can take advantage of all the Kokkos backends. The TpetraWrapper classes in deal.II are still not quite complete as compared to the TrilinosWrapper classes (using Epetra) but should be largely usable, also see Section 2.3 in "The deal.II library, Version 9.6", DOI 10.1515/jnma-2024-0137. Are there any particular functionalities you would like to see ported?
