Comparing Clusters and Supercomputers for Lattice QCD

 
S. Gottlieb, Indiana University

ABSTRACT
Since the development of the Beowulf project to build a parallel computer from commodity PC components there have been many such clusters built. The MILC QCD code has been run on a variety of clusters and supercomputers. Key design features are identified, and the cost effectiveness of clusters and supercomputers are compared. New opportunities in processors, motherboards and networking will also be discussed.
