Functions
int	Gauge_Update (const double d, double *pp, Complex *ut[2], Complex_f *ut_f[2])
	Gauge update for the integration step of the HMC.
int	Momentum_Update (const double d, const double *dSdpi, double *pp)
	Wrapper for the momentum update during the integration step of the HMC.
int	Leapfrog (Complex *ut[2], Complex_f *ut_f[2], Complex *X0, Complex *X1, Complex *Phi, double *dk[2], float *dk_f[2], double *dSdpi, double *pp, unsigned int *iu, unsigned int *id, Complex gamval[20], Complex_f gamval_f[20], const unsigned short gamin[16], Complex *sigval, Complex_f *sigval_f, unsigned short *sigin, const Complex jqq, const float beta, const float akappa, const float c_sw, const int stepl, const float dt, double *ancg, int *itot, const float proby)
	Leapfrog integrator. Each trajectory step takes the form of p->p+dt/2,u->u+dt,p->p+dt/2 In practice this is implemented for the entire trajectory as p->p+dt/2,u->u+dt,p->p+dt,u->u+dt,p->p+dt,...p->p+dt/2,u->u+dt,p->p+dt/2.
int	OMF2 (Complex *ut[2], Complex_f *ut_f[2], Complex *X0, Complex *X1, Complex *Phi, double *dk[2], float *dk_f[2], double *dSdpi, double *pp, unsigned int *iu, unsigned int *id, Complex gamval[20], Complex_f gamval_f[20], const unsigned short gamin[16], Complex *sigval, Complex_f *sigval_f, unsigned short *sigin, const Complex jqq, const float beta, const float akappa, const float c_sw, const int stepl, const float dt, double *ancg, int *itot, const float proby)
	OMF second order five step integrator.
int	OMF4 (Complex *ut[2], Complex_f *ut_f[2], Complex *X0, Complex *X1, Complex *Phi, double *dk[2], float *dk_f[2], double *dSdpi, double *pp, unsigned int *iu, unsigned int *id, Complex gamval[20], Complex_f gamval_f[20], const unsigned short gamin[16], Complex *sigval, Complex_f *sigval_f, unsigned short *sigin, const Complex jqq, const float beta, const float akappa, const float c_sw, const int stepl, const float dt, double *ancg, int *itot, const float proby)
	OMF fourth order eleven step integrator.
void	cuGauge_Update (const double d, double *pp, Complex *ut[2], dim3 dimGrid, dim3 dimBlock)
	CUDA wrapper for the gauge update during the integration step of the HMC.
