Spin glass simulations on the Janus architecture: A desperate quest for strong scaling 2013 Access copy available to the general public Unrestricted We describe Janus, an application-driven architecture for Monte Carlo simulations of spin glasses. Janus is a massively parallel architecture, based on reconfigurable FPGA nodes; it offers two orders of magnitude better performance than commodity systems for spin glass applications. The first generation Janus machine has been operational since early 2008; we are currently developing a new generation, that will be on line in early 2013. In this paper we present the Janus architecture, describe both implementations and compare their performances with those of commodity systems. info:eu-repo/grantAgreement/EC/FP7/247328/EU/Critical Phenomena in Random Systems/CRIPHERASY info:eu-repo/grantAgreement/ES/MEC/FIS2006-08533 info:eu-repo/grantAgreement/ES/MEC/FPA2004-02602 info:eu-repo/grantAgreement/ES/MICINN/FIS2007-60977 info:eu-repo/grantAgreement/ES/MICINN/FIS2009-12648-C03-02 info:eu-repo/grantAgreement/ES/MICINN/FIS2010-16587 info:eu-repo/grantAgreement/ES/MICINN/TEC2007-64188 info:eu-repo/grantAgreement/ES/MICINN/TEC2010-19207 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Baños, R.A.
