We have performed simulations both at fixed temperature and with an annealing protocol. Thanks to the Janus special-purpose computer, based on field-programmable gate array (FPGAs), we have been able to reach times equivalent to 0.01 s in experiments. We have studied the system relaxation both for high and for low temperatures, clearly identifying a dynamical transition point. This dynamical temperature is strictly positive and depends on the external applied magnetic field. We discuss different possibilities for the underlying physics, which include a thermodynamical spin-glass transition, a mode-coupling crossover, or an interpretation reminiscent of the random first-order picture of structural glasses2014http://zaguan.unizar.es/record/4813410.1103/PhysRevE.89.032140http://zaguan.unizar.es/record/48134oai:zaguan.unizar.es:48134info:eu-repo/grantAgreement/EC/FP7/247328/EU/Critical Phenomena in Random Systems/CRIPHERASYinfo:eu-repo/grantAgreement/ES/MEC/FIS2006-08533info:eu-repo/grantAgreement/ES/MICINN/FIS2010-16587info:eu-repo/grantAgreement/ES/MICINN/TEC2010-19207info:eu-repo/grantAgreement/ES/MINECO/FIS2012-35719-C02Physical Review E - Statistical, Nonlinear, and Soft Matter Physics 89, 3 (2014), 032140 [22 pp.]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
