gmx::anonymous_namespace{gpu_3dfft_sycl_rocfft.cpp} Namespace Reference

Classes
class	RocfftInitializer
	Provides RAII-style initialization of rocFFT library. More...
struct	RocfftPlan
	All the persistent data for planning an executing a 3D FFT. More...
struct	PlanSetupData
	Helper struct to reduce repetitive code setting up a 3D FFT plan. More...

Enumerations
enum	FftDirection : int { RealToComplex, ComplexToReal, Count }
	Model the kinds of 3D FFT implemented.

Functions
void	handleFftError (rocfft_status result, const std::string &msg)
	Helper for consistent error handling.
void	handleFftError (rocfft_status result, const std::string &direction, const std::string &msg)
	Helper for consistent error handling.
std::array< size_t, DIM >	makeRealStrides (ivec realGridSizePadded)
	Compute the stride through the real 1D array.
std::array< size_t, DIM >	makeComplexStrides (ivec complexGridSizePadded)
	Compute the stride through the complex 1D array.
size_t	computeTotalSize (ivec gridSize)
	Compute total grid size.
RocfftPlan	makePlan (const std::string &descriptiveString, rocfft_transform_type transformType, const PlanSetupData &inputPlanSetupData, const PlanSetupData &outputPlanSetupData, ArrayRef< const size_t > rocfftRealGridSize, const DeviceStream &pmeStream)
	Prepare plans for the forward and reverse transformation. More...

Variables
const std::array< const char *, rocfft_status_invalid_work_buffer+1 >	c_rocfftErrorStrings
	Strings that match enum rocfft_status_e in rocfft.h. More...

Function Documentation

RocfftPlan gmx::anonymous_namespace{gpu_3dfft_sycl_rocfft.cpp}::makePlan	(	const std::string &	descriptiveString,
		rocfft_transform_type	transformType,
		const PlanSetupData &	inputPlanSetupData,
		const PlanSetupData &	outputPlanSetupData,
		ArrayRef< const size_t >	rocfftRealGridSize,
		const DeviceStream &	pmeStream
	)

Prepare plans for the forward and reverse transformation.

Because these require device-side allocations, some of them must be done in a SYCL queue.
