We report on our study of the Riemannian Manifold HMC (RMHMC) algorithm with the mass
term for the gauge momenta replaced by rational functions of the gauge covariant Laplace operator.
A comparison of HMC and RMHMC on a 2+1+1 flavor dynamical ensemble with lattice spacing
𝑎 ∼0.05fm shows increased rate of change in long distance modes, identified by Wilson flowed
energy, per fermion molecular dynamics step.
