Functions
template<typename T>
__device__ void	Device::cuByGenLeft (T a[nc], const unsigned short gen)
	Multiply leaf (or part of one) by generator from left.
template<typename T>
__device__ void	Device::cuByGenRight (T a[nc], const unsigned short gen)
	Multiply leaf (or part of one) by generator from right.
template<typename T>
__device__ void	Device::Half_Leaf (complex< T > Leaves[nc], complex< T > *u11t, complex< T > *u12t, complex< T > a[nc], unsigned int *iu, unsigned int *id, const unsigned int i, const unsigned short mu, const unsigned short nu, const unsigned short leaf)
	Calculates the first half of the leaf for a clover term. We split it so that the force term can reuse the first half of the leaf.
template<typename T>
__device__ void	Device::Leaf (complex< T > *u11t, complex< T > *u12t, complex< T > Leaves[nc], unsigned int *iu, unsigned int *id, unsigned int i, const unsigned short mu, const unsigned short nu, const unsigned short leaf)
	Calculates a leaf for a clover term.
template<typename T>
__device__ void	Device::cuGLeft (T out[4], const T G[2], const T X[4])
	Multiplies \( X_{\mu\nu}\) by a gauge field from the left.
template<typename T>
__device__ void	Device::cuGRight (T out[4], const T G[2], const T X[4])
	Multiplies \( X_{\mu\nu}\) by a gauge field from the right.
template<typename T>
__device__ void	Device::cuGSandwich (T out[4], T tmp[4], const T Gl[2], const T X[4], const T Gr[2])
	Multiplies \( X_{\mu\nu}\) by a gauge field from the left and the right.
__device__ void	Device::GetBilinear (Complex_f Z[nc *nc], Bilinear_a Xmn, unsigned int ind)
	Loads the compacted bilinear form into a \(2\times2\) complex valued matrix.
template<typename T>
__global__ void	Kernels::Half_Leaves (complex< T > *hLeaves0, complex< T > *hLeaves1, complex< T > *u11t, complex< T > *u12t, unsigned int *iu, unsigned int *id, const unsigned short mu, const unsigned short nu)
	Calculates the products of the first two links in a plaquette.

__global__ void	Kernels::Full_Clover (complex< T > *clover1, complex< T > *clover2, complex< T > *u11t, complex< T > *u12t, unsigned int *iu, unsigned int *id, int mu, int nu)
	Calculates the clovers in all directions at all sites \( F_{\mu\nu}(n)=\frac{-i}{8a^2}\left(Q_{\mu\nu}(n)-Q_{\nu\mu}(n)\right)\).
template<typename T>
__global__ void	Kernels::cuCalcXmunu (Bilinear_a Xmunu, const complex< T > *X1, const complex< T > *X2, const complex< T > *sigval, const unsigned short *sigin, const unsigned short clov)
	Gets \(X_{\mu\nu}\) for the clover force.
template<typename T>
__global__ void	Kernels::Clov_Force (double *dSdpi, const complex< T > *u11t, const complex< T > *u12t, Bilinear_a Xmn, const complex< T > *sigval, const unsigned short *sigin, const unsigned int *iu, const unsigned int *id, const float akappa, const unsigned short mu, const unsigned short nu)
	cuGets the clover contribution to the force
template<typename T>
__global__ void	Kernels::ByClover (complex< T > *phi, complex< T > *r, complex< T > *clover1, complex< T > *clover2, complex< T > *sigval, const float akappa, unsigned short *sigin, bool dag)
	Clover analogue of the Dslash operation. This version acts on all flavours similar to Dslash and Dslash_d.
template<typename T>
__global__ void	Kernels::HbyClover (complex< T > *phi, complex< T > *r, complex< T > *clover1, complex< T > *clover2, complex< T > *sigval, const float akappa, unsigned short *sigin, bool dag)
	Clover analogue of the Hdslash operation. The H in front is for half, as we only act on the fermions of flavour 1.
int	cuClover (Complex_f *clover[nc], Complex_f *ut[nc], unsigned int *iu, unsigned int *id)
	CUDA wrapper for calculating the clovers in all directions at all sites \( F_{\mu\nu}(n)=\frac{-i}{8a^2}\left(Q_{\mu\nu}(n)-Q_{\nu\mu}(n)\right)\).
