Understand

We adopt CUDA-capable Graphic Processing Units (GPUs) for Coulomb, Landau and maximally Abelian gauge fixing in 3+1 dimensional SU(3) lattice gauge field theories.

The local overrelaxation algorithm is perfectly suited for highly parallel architectures.
Simulated annealing preconditioning strongly increases the probability to reach the global maximum of the gauge functional.
We give performance results for single and double precision.
