Understand

Recent developments have shown that a lot can be gained for QCD simulations from GPU hardware.

This can be exploited especially in the case of Ginsparg-Wilson fermions when the com putational costs are particularly high.
In this work, we use the Neuberger-Dirac operator as our realisation of Ginsparg-Wilson fermions, which greatly facilitate lattice investigations of decays like $K \to \pi\pi$.
We report on the ongoing study of our GPU implementation of the Neuberger-Dirac operator including the exact treatment of the low lying eigenmodes of the Wilson-Dirac operator.
