Arguments

Type	Intent	Optional	Attributes		Name
logical,	intent(in),	optional		::	enable_z_slab	Should dtFFT use Z-slab optimization or not.
type(dtfft_platform_t),	intent(in),	optional		::	platform	Selects platform to execute plan.
type(dtfft_stream_t),	intent(in),	optional		::	stream	Main CUDA stream that will be used in dtFFT.
type(dtfft_backend_t),	intent(in),	optional		::	backend	Backend that will be used by dtFFT when `effort` is `DTFFT_ESTIMATE` or `DTFFT_MEASURE`.
logical,	intent(in),	optional		::	enable_mpi_backends	Should MPI GPU Backends be enabled when `effort` is `DTFFT_PATIENT` or not.
