Query: Implementation of the Neuberger-Dirac operator on GPUs   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. Our benchmarks show that
we achieve speed-up factors of around 23 and 16 in single and double precision,
respectively.
