Description

Currently, the deal.II example hands off memory in the host space, even when using Kokkos + a libCEED GPU backend. We should update the example to do the handoff with a GPU pointer.

Contributor guide

Research direction
Inspect the deal.II example in libCEED to understand current host memory handoff, then modify it to allocate and handoff GPU memory using Kokkos or appropriate libCEED backend.
