Abstract

This is a package for lattice QCD codes. Treating gauge fields (links), gauge actions with MPI and autograd.

This package will be used in LatticeQCD.jl.

What this package can do:

This package has following functionarities

• SU(Nc) (Nc > 1) gauge fields in 2 or 4 dimensions with arbitrary actions.
• U(1) gauge fields in 2 dimensions with arbitrary actions.
• Configuration generation
  • Heatbath
  • quenched Hybrid Monte Carlo
• Gradient flow via RK3
• I/O: ILDG and Bridge++ formats are supported (c-lime will be installed implicitly with CLIME_jll )
• MPI parallel computation (experimental. not shown)

Dynamical fermions will be supported with LatticeDiracOperators.jl.

In addition, this supports followings

• Autograd for functions with SU(Nc) variables
• Stout smearing (exp projecting smearing)
• Stout force via backpropagation

Autograd can be worked for general Wilson lines except for ones have overlaps.
