The LHMC Algorithm for Free Field Theory: Reexamining Overrelaxation
Ivan Horvath, A. D. Kennedy
We analyze the autocorrelations for the LHMC algorithm in the context of free field theory. In this case this is just Adler's overrelaxation algorithm. We consider the algorithm wi…
Thermodynamics of lattice QCD with two light quark flavours on a 16^3 x 8 lattice II
S. Gottlieb, U. M. Heller, A. D. Kennedy +8
We have extended our earlier simulations of the high temperature behaviour of lattice QCD with two light flavours of staggered quarks on a lattice to lower quark ma…
Non-Reversibility of Molecular Dynamics Trajectories
R. G. Edwards, Ivan Horvath, A. D. Kennedy
We study the non-reversibility of molecular dynamics trajectories arising from the amplification of rounding errors. We analyse the causes of such behaviour and give arguments, ind…
QCD with dynamical Wilson fermions at
K. M. Bitar, R. G. Edwards, U. M. Heller +1
We study QCD with two flavors of dynamical Wilson fermions at and three values of . The corresponding pion masses are 0.375, 0.324 and 0.262 in lattice units, with pion…
QCD Function with Two Flavors of Dynamical Wilson Fermions
K. M. Bitar, R. G. Edwards, U. M. Heller +1
We test the asymptotic scaling behavior of state-of-the-art simulations of QCD with two flavors of light Wilson fermions. This is done by matching and masses on lattices of…
Status of the 0.8 Teraflops Supercomputer at Columbia
I. Arsenin, D. Chen, N. Christ +14
The first stage in the construction of the 0.8 Teraflops Supercomputer at Columbia, a working, two node parallel computer, has been successfully completed. The next stage, a 512 no…
