Member Function Documentation

operator()() [1/2]

void quda::MultiShiftCG::operator() ( std::vector< ColorSpinorField * >  out, ColorSpinorField &  in  )

inlinevirtual

Run multi-shift and return Krylov-space at the end of the solve in p and r2_old_arry.

Parameters

out	std::vector of pointer to solutions for all the shifts.
in	right-hand side.

Implements quda::MultiShiftSolver.

Definition at line 1279 of file invert_quda.h.

operator()() [2/2]

void quda::MultiShiftCG::operator()	(	std::vector< ColorSpinorField * >	x,
		ColorSpinorField &	b,
		std::vector< ColorSpinorField * > &	p,
		double *	r2_old_array
	)

Run multi-shift and return Krylov-space at the end of the solve in p and r2_old_arry.

Parameters

out	std::vector of pointer to solutions for all the shifts.
in	right-hand side.
p	std::vector of pointers to hold search directions. Note this will be resized as necessary.
r2_old_array	pointer to last values of r2_old for old shifts. Needs to be large enough to hold r2_old for all shifts.
