Description

README (Written by Claudio Bonanno: claudio.bonanno@fi.infn.it)

Archives of thermalized and well-decorrelated gauge configurations

Discretization: Symanzik-improved gauge action & N_f = 2+1 flavors of rooted stout staggered fermions with physical quark masses
and physical pion mass

Theory details: T=230 MeV, 48^3 x 12 lattice with a lattice spacing a = 0.07149 fm.

Algorithm: standard RHMC in the presence of a topological bias potential. For the details about the topological bias potential see https://arxiv.org/abs/1807.07954

The topological bias potential can be removed afterwards through standard reweighting.

Conf name: stored_conf.${conf_ID} where conf_ID is equal to the RHMC step the conf has been saved.

Conf have been saved every 30 RHMC seps in binary files according to the ILDG format for standard C programs.

For more details about the ILDG format see, e.g., https://www-zeuthen.desy.de/~pleiter/ildg/ildg-file-format-1.1.pdf

The auto-correlation time of Q is about 8 RHMC steps in our setup.

Notes

Confs generated with the OpenStaPLE code, written in C with OpenACC support (soon to be published open access on GitHub). For more info see related article https://arxiv.org/abs/1801.01473 (relative to the 2018 version of the code).
