Abstract
The computational requirements and dynamics of Monte. Carlo simulations of unquenched QCD incorporating the infrared quark eigenmodes (up to approxima te to Lambda(QCD)) exactly and UV modes via a loop representation are discu ssed. The accuracy of such a loop representation is studied for a variety o f lattice volumes and quark masses. The method has been successfully applie d for lattices up to 10(3)x20 at a similar or equal to 0.17F with improved (clover) action, and allows simulations at or near kappa critical.
