Landau Gauge Fixing on GPUs

Cardoso, Nuno, Silva, Paulo J., Bicudo, Pedro et al.

Understand

In this paper we present and explore the performance of Landau gauge fixing in GPUs using CUDA.

We consider the steepest descent algorithm with Fourier acceleration, and compare the GPU performance with a parallel CPU implementation.
Using $32^4$ lattice volumes, we find that the computational power of a single Tesla C2070 GPU is equivalent to approximately 256 CPU cores.
