QPACE -- a QCD parallel computer based on Cell processors
H. Baier, H. Boettiger, M. Drochner +32
QPACE is a novel parallel computer which has been developed to be primarily used for lattice QCD simulations. The compute power is provided by the IBM PowerXCell 8i processor, an e…
Status of the QPACE Project
H. Baier, H. Boettiger, M. Drochner +27
We give an overview of the QPACE project, which is pursuing the development of a massively parallel, scalable supercomputer for LQCD. The machine is a three-dimensional torus of id…
QCD on the Cell Broadband Engine
F. Belletti, G. Bilardi, M. Drochner +16
We evaluate IBM's Enhanced Cell Broadband Engine (BE) as a possible building block of a new generation of lattice QCD machines. The Enhanced Cell BE will provide full support of do…
2+1 Flavor QCD simulated in the epsilon-regime in different topological sectors
P. Hasenfratz, D. Hierl, V. Maillart +4
We generated configurations with the parametrized fixed-point Dirac operator D_{FP} on a (1.6 fm)^4 box at a lattice spacing a=0.13 fm. We compare the distributions of the three lo…
First results in QCD with 2+1 light flavors using the fixed-point action
Anna Hasenfratz, Peter Hasenfratz, Dieter Hierl +2
This is a progress report on 2+1 flavor simulation with the FP action on a lattice with spatial size L=1.2fm. Since m_{ud} is quite small in our simulation we are in the delta regi…
Search for the Theta^+(1540) in lattice QCD
Christian Hagen, Dieter Hierl, Andreas Schäfer
We report on a study of the pentaquark Theta^+(1540), using a variety of different interpolating fields. We use Chirally Improved fermions in combination with Jacobi smeared quark…
