Description

Simulating QCD in the traditional way on very large lattices leads to conceptual and technical issues with impact on performance and reliability. In view of master-field simulations, introduced at Lattice 2017, simulations with dynamical fermions are particularly challenging and require additional stabilising measures to reach physical point lattices without compromising the quality of the simulation. The proposed stabilising measures comprise algorithmic changes as well as a new O(a)-improved Wilson action with exponential clover term.
In this talk, the motivation for stabilising measures and its effects are reviewed as both, standard-sized and master-field simulations, profit from its implementation. Furthermore, the current status and prospects of QCD master-field simulations are presented.
