Status of the QCDSP project
Dong Chen, Ping Chen, Norman H. Christ +15
We describe the completed 8,192-node, 0.4Tflops machine at Columbia as well as the 12,288-node, 0.6Tflops machine assembled at the RIKEN Brookhaven Research Center. Present perform…
QCDSP - A status report
QCDSP Collaboration, Dong Chen, Ping Chen +16
The QCDSP machine at Columbia University has grown to 2,048 nodes achieving a peak speed of 100 Gigaflops. Software for quenched and Hybrid Monte Carlo (HMC) evolution schemes has…
Improved actions of the staggered fermion
Yubing Luo
We have studied improved lattice QCD with the staggered fermion by using Symanzik's program. We find that there are 5 dimension-6 fermion bilinears and gauge operators. In…
On-shell improved lattice QCD with staggered fermions
Yubing Luo
By using Symanzik's improvement program, we study on-shell improved lattice QCD with staggered fermions. We find that there are as many as 15 independent lattice operators of dimen…
Staggered fermions and their improvements
Yubing Luo
Expanding upon the arguments of Sharpe, we explicitly implement the Symanzik improvement program demonstrating the absence of order terms in the staggered fermion action. We pr…
Improvement of the Staggered Fermion Operators
Yubing Luo
We present a complete and detailed derivation of the finite lattice spacing corrections to staggered fermion matrix elements. Expanding upon arguments of Sharpe, we explicitly impl…
