Well yes and no. The documents released by ORNL lists OpenMP-5 as the
provided alternative (path forward) for OpenACC applications.

In a similar way it notes HIP as the replacement for CUDA.

Personally I think that it's a case of maintained supported programming
models but change of specific technologies. Except for apps on
frameworks such as Kokkos and Raja which I suspect will work without
porting (performance porting probably needed though).

In a sense (arch/model, not specific tech) these machines (in
succession) are quite similar; Titan -> Summit -> Frontier.
