Computers for Lattice QCD

The overriding objective of present work in lattice QCD is to achieve an accurate representation of continuum QCD and to use this ability to study physically important properties of the underlying theory. This research demands a combination of efficient numerical algorithms, physical quantities appropriately represented for numerical study and fast computers to carry out the needed calculations...

Lattice QCD on Small Computers

We demonstrate that lattice QCD calculations can be made 103– 10 times faster by using very coarse lattices. To obtain accurate results, we replace the standard lattice actions by perturbativelyimproved actions with tadpole-improved correction terms that remove the leading errors due to the lattice. To illustrate the power of this approach, we calculate the static-quark potential, and the charm...

Computers for Lattice Field

Parallel computers dedicated to lattice eld theories are reviewed with emphasis on the three recent projects, the Teraaops project in the US, the CP-PACS project in Japan and the 0.5-Teraaops project in the US. Some new commercial parallel computers are also discussed. Recent development of semiconductor technologies is brieey surveyed in relation to possible approaches toward Teraaops computers.

Opportunities for Lattice QCD Thermodynamics Lattice QCD Executive Committee

Over the next decade high performance computing resources will reach the petaflops scale. Coupled with current and planned experiments at RHIC, FAIR, and the LHC, these computational resources will offer significant opportunities for the advancement of our understanding of the properties of strongly interacting matter at high temperatures and densities. We describe expected quantitative and qua...
