Function Documentation

loop() [1/6]

template<typename Functor >

ALWAYS_INLINE void BoxLoops::loop	(	const Box &	a_computeBox,
		Functor &&	kernel,
		const IntVect &	a_stride = IntVect::Unit
	)

Launch a C++ kernel over a regular grid.

The stride argument lets the user use different strides along the different coordinate axes. The default is to use a stride of one along each coordinate. Note that the stride must be positive for each coordinate axis.

Parameters

[in]	a_computeBox	Computation box
[in,out]	a_kernel	Kernel to launch.
[in]	a_stride	Stride for each loop.

loop() [2/6]

template<typename Functor >

ALWAYS_INLINE void BoxLoops::loop	(	const DenseIntVectSet &	a_ivs,
		Functor &&	a_kernel
	)

Launch a C++ kernel over a subset of cells.

Parameters

[in,out]	a_cells	Grid cells where we launch the kernel.
[in,out]	a_kernel	Kernel to launch

loop() [3/6]

template<typename Functor >

ALWAYS_INLINE void BoxLoops::loop	(	const IntVectSet &	a_ivs,
		Functor &&	a_kernel
	)

Launch a C++ kernel over a subset of cells.

Parameters

[in,out]	a_cells	Grid cells where we launch the kernel.
[in,out]	a_kernel	Kernel to launch

loop() [4/6]

template<typename T , typename Functor >

ALWAYS_INLINE void BoxLoops::loop	(	const Vector< T > &	a_subset,
		Functor &&	a_kernel
	)

Launch a C++ kernel over a specified subset of something.

Parameters

[in,out]	a_subset	Subset. E.g. a std::vector<VolIndex>
[in,out]	a_kernel	Kernel to launch

loop() [5/6]

template<typename Functor >

ALWAYS_INLINE void BoxLoops::loop	(	FaceIterator &	a_iter,
		Functor &&	a_kernel
	)

Launch a C++ kernel over faces.

Parameters

[in,out]	a_faceit	Grid faces where we launch the kernel.
[in,out]	a_kernel	Kernel to launch

loop() [6/6]

template<typename Functor >

ALWAYS_INLINE void BoxLoops::loop	(	VoFIterator &	a_iter,
		Functor &&	a_kernel
	)

Launch a C++ kernel over cut-cells.

Parameters

[in,out]	a_vofit	Grid cells where we launch the kernel.
[in,out]	a_kernel	Kernel to launch
