In the current release, \texttt{LinearAlgebra::distributed::Vector} and the
\texttt{CUDAWrappers::Matrix\allowbreak{}Free} framework are using \kokkos. This allows them
-to work on all the architectures supported by \kokkos. The \kokkos backend used
-by \dealii is \texttt{Kokkos::DefaultExecutionSpace} which corresponds to the
-highest available backend in the hierarchy device, host-parallel, and host-serial
+to work on all the architectures supported by \kokkos. In particular, the step-64 example
+can now also be run on the CPU and doesn't require a GPU anymore. \\
+The \kokkos backend used by \dealii is \texttt{Kokkos::DefaultExecutionSpace} which corresponds

at the time Kokkos was configured.
