kml_fft(f/h)_mpi_execute_dft_r2c

Execute the created FFT plan. kml_fft(f/h)_mpi_execute_dft_r2c supports new input and output parameters that are different from those associated with the plan.

Interface Definition

C interface:

void kml_fft_mpi_execute_dft_r2c(const kml_fft_plan p, double *in, kml_fft_complex *out);

void kml_fftf_mpi_execute_dft_r2c(const kml_fftf_plan p, float *in, kml_fftf_complex *out);

void kml_ffth_mpi_execute_dft_r2c(const kml_ffth_plan p, __fp16 *in, kml_ffth_complex *out);

Parameters

Parameter	Data Type	Description	Input/Output
p	Double precision: const kml_fft_plan Single precision: const kml_fftf_plan Half precision: const kml_ffth_plan	FFT plan obtained by calling the plan function.	Input
in	Double precision: double* Single precision: float* Half precision: __fp16*	Inputs the data to be transformed.	Input
out	Double precision: kml_fft_complex* Single precision: kml_fftf_complex* Half precision: kml_ffth_complex*	Outputs the data generated using FFT.	Output
