Member Function Documentation

void cps::Gnone::AllStaple (  Matrix &  stap, const int *  x, int  mu )  [virtual]

Not implemented. Implements cps::Lattice. Definition at line 124 of file g_none.C. References cps::ERR, and cps::Error::NotImplemented().

ForceArg cps::Gnone::EvolveMomGforce (  Matrix *  mom, Float  step_size )  [virtual]

Molecular dynamics evolution of the conjugate momentum. The momentum is evolved for a single molecular dynamics timestep using the force from the pure gauge action. Parameters: mom  The momentum matrices on all links. step_size  The molecular dynamics timestep used in the numerical integration. Postcondition: mom is assigned the value of the momentum after the molecular dynamics evolution. Implements cps::Lattice. Definition at line 94 of file g_none.C. References cps::Verbose::Func(), and cps::VRB.

void cps::Gnone::GactionGradient (  Matrix &  grad, int *  x, int  mu )  [virtual]

Calculates the partial derivative of the gauge action w.r.t. the link U_mu(x). Parameters: grad  The computed gradient. x  The coordinates of the lattice site. mu  The direction of the link. Implements cps::Lattice. Definition at line 119 of file g_none.C. References cps::ERR, and cps::Error::NotImplemented().

GclassType cps::Gnone::Gclass (   )  [virtual]

Returns the type of gauge action. Implements cps::Lattice. Definition at line 67 of file g_none.C. References cps::GclassType.

void cps::Gnone::GforceSite (  Matrix &  force, int *  x, int  mu )

Calculates the gauge force at site x and direction mu. In this case, of course, the force is zero. Parameters: force  The computed force from the gauge action. x  the lattice site coordinates. mu  The direction mu. Todo: Should this not be be a virtual Lattice method? Definition at line 81 of file g_none.C. References cps::Verbose::Func(), cps::VRB, and cps::Matrix::ZeroMatrix().

Float cps::Gnone::GhamiltonNode (   )  [virtual]

Computes the pure gauge action on the local sublattice. Returns: The value of the pure gauge action on this node. Implements cps::Lattice. Definition at line 106 of file g_none.C. References cps::Float, cps::Verbose::Func(), and cps::VRB.
