In this talk I will show the results concerning a new technique for the determination of critical parameters (critical exponents and critical temperature) for a system undergoing a second-order phase transition in the out-of-equilibrium relaxation regime. The method is completely general and relies on a finitetime/finite-size scaling Ansatz justified in the framework of the Renormalization Group (RG) . I will show
the results concerning the three-dimensional Ising spin-glass for which such an approach is mostly useful due to its extremely slow dynamics. I will also discuss the numerical technique (Metropolis Montecarlo) and its implementation on single- and multi-GPU systems, paying some attention at pseudo-random numbers generation .
