  1. USQCD ILDG StatusSept 2011 Rich Brower

  2. MILC Asqtad 2+1 flavor • Complete set on ILDG as described in Rev.Mod.Phys. 82 (2010) 1349-1417arXiv:0903.3598 [hep-lat] • 32 ensembles • Lattice spacings ranging from 0.045 to 0.18 fm • m_ud/m_s from 0.05 to 0.6

  3. MILC HISQ 2+1+1 flavor • Ready to be archived: • 4 ensembles: • 0.15 fm m_ud/m_s = 0.1 and 0.2 • 0.12 fm m_ud/m_s = 0.2 • 0.09 fm m_ud/m_s = 0.2 • For more details see: http://physics.indiana.edu/~sg/milc/MILC_Lattice_Generation_for_SciDAC.html

  4. MILC HISQ 2+1+1+1 plans • Eventually MILC plans to generate a HISQ resource similar to the asqtad resource • a = 0.15 - 0.045 fm • m_ud/m_s = 1/5, 1/10, 1/27 Note the last gives a physical Goldstone pion • Three volumes planned for a = 0.12 fm for finite volume study

  5. RBC-UKQCD DWF 2+1 flavor • All 2+1 flavor DWF+Iwasaki lattices (Ls = 16) will be made publicly available through ILDG as soon as possible (Oliver Witzel) • 16^3 a approx 0.113 fm m_u = 0.01, 0.02, 0.03 with ms = 0.04 • 16^3 a approx 0.113 fm m_u = 0.01, 0.02 with ms = 0.032 • 24^3 a approx 0.113 fm m_u = 0.005, 0.01, 0.02, 0.03 with ms = 0.04 • 32^3 a approx 0.086 fm m_u = 0.004, 0.006, 0.008 with ms = 0.03 (some lattices are already available under UKQCD listing) • 2+1 flavor DWF+Iwasaki+DSDR lattices (Ls = 32) are only available on a per request basis • 32^3 a approx 0.144 fm m_u = 0.001, 0.0042 with ms = 0.045

  6. RBC-UKQCD non-ILDG site • https://qcdlattices.bnl.gov/ • NERSC-format lattices from RBC-UKQCD • some restricted, some open

  7. Aniostropic Wilson Clover • Lattice Volume: • 24^3x128 • m_pi ~ 380 MeV: ~11,000 thermalized trajectories • m_pi ~ 230 MeV: ~11,760 thermalized trajectories • 32^3x256 • m_pi ~ 380 MeV: 3116 thermalized trajectories • m_pi ~ 230 MeV: ~8000 trajectories • Current generation: • 40^3x256, thermalizing at both masses, • m_pi ~ 380MeV may be close to thermalization

  8. A NERSC ILDG site • An ILDG mirror site under construction • James Hetrick • Slow, for lack of manpower • Eventually hope to serve files with some ILDG grid tools • No certificates required for downloads?
