**Parallel kinetic Monte Carlo simulation of Coulomb glasses**

We develop a parallel rejection algorithm to tackle the problem of low acceptance in Monte Carlo methods, and apply it to the simulation of the hopping conduction in Coulomb glasses using Graphics Processing Units, for which we also parallelize the update of local energies. In two dimensions, our parallel code achieves speedups of up to two orders of magnitude in computing time over an equivalent serial code. We find numerical evidence of a scaling relation for the relaxation of the conductivity at different temperatures.

**Numerical approaches on driven elastic interfaces in random media**

We present the main concepts behind the statistical and dynamical properties of elastic systems in disordered media, focused on the relation between the rough geometry and collective transport properties in driven steady-states. We review the numerical approaches that allow to analyze the equilibrium, creep, and depinning regimes of motion in these models.

**Nonsteady relaxation and critical exponents at the depinning transition**

We study the nonsteady relaxation of a driven one-dimensional elastic interface at the depinning transition by extensive numerical simulations concurrently implemented on graphics processing units. Above a first, nonuniversal microscopic time regime, we find a nontrivial long crossover towards the nonsteady macroscopic critical regime. In order to avoid fitting effective exponents with a systematic bias we implement a practical criterion of consistency and perform large-scale ( ) simulations for the nonsteady dynamics of the continuum displacement quenched Edwards-Wilkinson equation, getting accurate and consistent depinning exponents for this class: , , , and .

**-state Potts model metastability study using optimized GPU-based Monte Carlo ****algorithms**

We implemented a GPU-based parallel code to perform Monte Carlo simulations of the two-dimensional -state Potts model. The possibility of performing high speed simulations at large enough system sizes allowed us to tackle an old standing question posed by k. Binder in 1981, regarding the existence or not of specific heat singularities at spinodal temperatures different of the transition one.

**Relaxation in the -state Potts model**

We studied the nonequilibrium dynamics of the -state Potts model in the square lattice, after a quench to subcritical temperatures. By means of a continuous time Monte Carlo algorithm ͑nonconserved order parameter dynamics͒ we analyzed the long term behavior of the energy and relaxation time for a wide range of quench temperatures and system sizes. For we found the existence of different dynamical regimes, according to quench temperature range.
