is_backend_compatible Function

private pure function is_backend_compatible(backend1, backend2)

Checks if two communication backends are compatible

Backends are compatible if they belong to the same family: MPI backends are compatible with each other, NCCL with NCCL, NVSHMEM with NVSHMEM.

@return .true. if backends are compatible, .false. otherwise

Arguments

Type IntentOptional Attributes Name
type(dtfft_backend_t), intent(in) :: backend1

First backend to compare
type(dtfft_backend_t), intent(in) :: backend2

Second backend to compare

Return Value logical
