Steven Gottlieb (Fermilab/Indiana University)
TL;DR
This paper estimates the computational cost of dynamical quark simulations using improved staggered quarks, indicating that reaching a lattice spacing of 0.045 fm requires a few tens of Teraflop years of computing.
Contribution
It provides a cost estimate for advanced lattice QCD simulations with improved staggered quarks based on current and planned computational efforts.
Findings
A few tens of Teraflop years needed for 0.045 fm lattice spacing
Cost estimates based on current and planned simulations
Guidance for future computational planning in lattice QCD
Abstract
The cost of dynamical quark simulations with improved staggered quarks is estimated based on current and planned running by the MILC collaboration. I find that a few 10s of Teraflop years should be sufficient to calculate down to a lattice spacing of 0.045 fm.
