Converters

FermiQCD can import gauge configurations in multiple file formats:

NERSC (3x3 and 3x2)

ILDG

QDP

MILC

UKQCD

ASCII formats

To import just type:

	    fermiqcd/universal_converter.py [input_filename]

The converter figures out the type of source.

Note that FermiQCD fields are always stored using the native MDP file format mentioned in the MDP Tutorial. This file format supports any field object on any number of dimensions and it is independent on the partitioning of the field.

Fully Object Oriented
gauge_field U(lattice,Nc);
cout << U(x+mu,nu);

Natural Linear Algebra
mdp_matrix A(Nc,Nc);
cout << inv(A*A)+exp(3*I*A);

Local PRNG
forallsites(x)
cout << lattice.random(x).SU(Nc);

Parallel but trasparent
forallsites(x)
psi(x)=U(x,mu)*psi(x+mu);
psi.update();

Arbitrary lattice dimensions
int box[]={4,4,4,4,4,4};
mdp_lattice lattice(6,box);

Variety of fields
mdp_field<float> f(lattice);
gauge_field U(lattice,Nc);
fermi_field psi(lattice,Nc);
staggered_field phi(lattice,Nc);
dwfermi_field chi(lattice,Nc);
(and more...)

Variety of actions
Wilson, Clover, unisotropic,
Asqtad, Domain Wall, etc...

And algorithms
Minimum Residue, Stabilized Biconjugate Gradient, BiCGStabUML, Lanczos, etc.
