Recent development and perspectives of machines for lattice QCD
Thomas Lippert
TL;DR
This paper reviews recent advancements in cluster computer technology and evaluates their potential for lattice QCD simulations, focusing on developments like QCDOC and apeNEXT, and presents a case study of a cost-effective 512-processor cluster.
Contribution
It provides an assessment of the current state and future prospects of cluster computers for lattice QCD, including specific developments like QCDOC and apeNEXT.
Findings
QCDOC and apeNEXT are significant developments in lattice QCD computing.
A 512-processor cluster can achieve better than 1$/Mflops cost efficiency.
The LatFor test case demonstrates the practical application of these clusters.
Abstract
I highlight recent progress in cluster computer technology and assess status and prospects of cluster computers for lattice QCD with respect to the development of QCDOC and apeNEXT. Taking the LatFor test case, I specify a 512-processor QCD-cluster better than 1$/Mflops.
