Detailed Description

template<typename ComplexField>
class ippl::FFT< CCTransform, ComplexField >

complex-to-complex FFT class

Member Function Documentation

transform()

template<typename ComplexField >

void ippl::FFT< CCTransform, ComplexField >::transform	(	TransformDirection	direction,
		ComplexField &	f
	)

Perform in-place FFT

Parameters

direction	Forward or backward transformation
f	Field whose transformation to compute (and overwrite)

This copy to a temporary Kokkos view is needed because of following reasons: 1) heffte wants the input and output fields without ghost layers 2) heffte accepts data in layout left (by default) even though this can be changed during heffte box creation

warmup()

template<typename ComplexField >

void ippl::FFT< CCTransform, ComplexField >::warmup

(

ComplexField &

f

)

Warmup the FFT object by forward & backward FFT on an empty field

Parameters

f	Field whose transformation to compute (and overwrite)
