HISQ and the MILC code Plaquette test of MILC code versus Kit’s code. Tested Alexei’s MILC inverter against Eduardo’s on 4 3 8 lattice. Doug Toussaint used HISQ inverter on 1/8 fm configs by computing the pion spectrum on an ensemble (m l /m s 0.010/0.050). Good agreement with HPQCD results. MILC will write new optimized versions of the HISQ routines, as more runs are done. Dynamical HISQ – p. 6
RHMC detM α = ∫ Dφ † Dφe −φ† r 2 (M)φ where r(x) = x −α/2 (rational approximation). RHMC is an exact algorithm, also allows larger δt than R algorithm ( δt ∼ 2/3m l ) so is faster (Kennedy/Clark claim 7 times better). MILC are now using the exact RHMC/RHMD algorithm for generating configurations (talk at ILDG11). Dynamical HISQ – p. 7
