@jeremylt I am wondering whether it is possible to extract the resource information from Kokkos and pass it to libCEED or what the best approach is to keep them in sync?

All libCEED backends can accept CPU pointers for vectors, so what we do in PETSc is
-
Create the user requested libCEED backend
-
Request the preferred memory space (CEED_MEM_HOST or CEED_MEM_DEVICE) of this libCEED backend
-
Set PETSc to use the requested memory space
I think a simpler version of this could be to request the libCEED backend's preferred memory space and hand off pointers in that memory space.

As suggested in #1436 (comment), this PR adds a deal.II example using Kokkos. The matrix-free infrastructure in deal.II that uses Kokkos is not as mature so that I only run BP1 (without overintegration) and BP5.
