Accelerating multigrid with streaming chiral SVD for Wilson fermions in lattice QCD
Travis Whyte, Andreas Stathopoulos, Eloy Romero
A modification to the setup algorithm for the multigrid preconditioner of Wilson fermions in lattice QCD is presented. A larger basis of test vectors than that used in conventional…

Chiral rank- truncations for the multigrid preconditioner of Wilson fermions in lattice QCD
Travis Whyte, Andreas Stathopoulos, Eloy Romero
We present a modification to the setup algorithm for the multigrid preconditioner of Wilson fermions in lattice QCD. A larger number of test vectors than that used in conventional…
