Detailed Description

Abstract class with common code for basic fft and fftw implementation

Use FFTDataContainer_arrays as Data container (2 arrays)

Don't define FFT_M2L and FFT_M2L_vec, but define FFT_M2L_2way the code using the acceleration should downcast its FFTAcceleration to the FFTAcceleration_2Way class and use FFT_M2L_2way instead of FFT_M2L

Member Function Documentation

FFT_initialize_Target()

void FFTAcceleration_2wayM2L::FFT_initialize_Target ( FFTAccelerableExpansion &  Expansion )

virtual

Initialize a Target expansion's FFTDatacontainer (schould be to a full 0 FFTDatacontainer)

Parameters

FFTAccelerableExpansion

& Expansion

Implements FFTAccelerationAPI.

FFT_M2L()

void FFTAcceleration_2wayM2L::FFT_M2L ( FFTAccelerableExpansion &  Source, FFTAccelerableExpansion &  Target, FFTDataContainer *  TransferFunction  )

inlinevirtual

M2L operator, performs the M2L in fourier space, usually an entrywise product (or more complexe scheme if needed, see blocks implementations)

All parameters needs to be initialized using the previous methods The TransferFunction should come from a TransferFunctionManager

Parameters

FFTAccelerableExpansion	& Source
FFTAccelerableExpansion	& Target
FFTDataContainer*	TransferFunction

Implements FFTAccelerationAPI.

FFT_M2L_2way()

void FFTAcceleration_2wayM2L::FFT_M2L_2way ( FFTAccelerableExpansion &  Source1, FFTAccelerableExpansion &  Source2, FFTAccelerableExpansion &  Target1, FFTAccelerableExpansion &  Target2, FFTDataContainer *  TransferFunction  )

virtual

M2L using 2way scheme (see doc/2wayM2L)

Implements FFTAccelerationAPI_2Way.

FFT_M2L_2way_vec()

void FFTAcceleration_2wayM2L::FFT_M2L_2way_vec ( FFTAccelerableExpansion &  Source1, FFTAccelerableExpansion &  Source2, FFTAccelerableExpansion &  Target1, FFTAccelerableExpansion &  Target2, FFTDataContainer *  TransferFunction  )

virtual

Implements FFTAccelerationAPI_2Way.

FFT_M2L_vec()

void FFTAcceleration_2wayM2L::FFT_M2L_vec ( FFTAccelerableExpansion &  Source, FFTAccelerableExpansion &  Target, FFTDataContainer *  TransferFunction  )

inlinevirtual

M2L operator, performs the M2L in fourier space, usually an entrywise product (or more complexe scheme if needed, see blocks implementations)

Uses vectorization of the loops

All parameters needs to be initialized using the previous methods The TransferFunction should come from a TransferFunctionManager

Parameters

FFTAccelerableExpansion	& Source
FFTAccelerableExpansion	& Target
FFTDataContainer*	TransferFunction

Implements FFTAccelerationAPI.
