About the archive

This Archive stores gauge configurations and other data of lattice QCD, and make them available to lattice field theory community world-wide. The Archive is maintained by the Center for Computational Sciences, Univ. of Tsukuba, as a part of Japan Lattice Data Grid (JLDG).

Files stored

We have two sets of files in the Archive.

Two-flavor full QCD configurations contributed by the CP-PACS Collaboration. There are three sets of files corresponding to three lattice spacings, all generated with the renormalization-group improved Iwasaki gluon action and the Wilson-clover quark action with tadpole-improved cover coefficient.
Details of the 2-flavor configurations are given here.
2+1 flavor full QCD configurations by the CP-PACS and JLQCD Collaborations. They were generated at three lattice spacings with a fully O(a) improved action -- combining the renormalization-group improved Iwasaki gluon action and a nonperturbatively O(a) improved Wilson-clover quark action -- and adopting an exact HMC+PHMC algorithm.
Details of the 2+1 flavor configurations are given here.

Archived configurations are formatted with the ILDG standard. Ensemble XML files and configuration XML files are based on QCDmlEnsemble1.4.1 and QCDmlConfig1.3.0, respectively. Follow this link to search ensembles/configurations and to download configurations.

International Lattice Data Grid

This Archive is a part of JLDG, one of regional grids of International Lattice Data Grid (ILDG). The query system of the Archive is designed to eventually allow world-wide seach and retrieval of configurations stored in ILDG.
