Graphics processing unit implementation of lattice Boltzmann models for flowing soft systems.

A graphic processing unit (GPU) implementation of the multicomponent lattice Boltzmann equation with multirange interactions for soft-glassy materials [``glassy'' lattice Boltzmann (LB)] is presented. Performance measurements for flows under shear indicate a GPU/CPU speed up in excess of 10 for ${1024}^{2}$ grids. Such significant speed up permits to carry out multimillion time-steps simulations of ${1024}^{2}$ grids within tens of hours of GPU time, thereby considerably expanding the scope of the glassy LB toward the investigation of long-time relaxation properties of soft-flowing glassy materials.
