◆ createCoarseOp()

void quda::DiracCloverHasenbuschTwistPC::createCoarseOp	(	GaugeField &	Y,

		const Transfer &	T,
		double	kappa,
		double	mass = `0.`,
		double	mu = `0.`,

virtual

Create the coarse even-odd preconditioned clover operator. Unlike the Wilson operator, the coarsening of the preconditioned clover operator differs from that of the unpreconditioned clover operator, so we need to specialize it.

Parameters

T[in]	Transfer operator defining the coarse grid
Y[out]	Coarse link field
X[out]	Coarse clover field
kappa	Kappa parameter for the coarse operator
mass	Mass parameter for the coarse operator (set to zero)
