Superfluidity is a generic feature of various quantum systems at low temperatures. It has been experimentally confirmed in many condensed matter systems, in He-3 and He-4 liquids, in nuclear systems, including nuclei and neutron stars, in both fermionic and bosonic cold atoms in traps, and it is also predicted to show up in dense quark matter. The time-dependent density functional theory (TDDFT) is, to date, the only microscopic method that allow to investigate fermionic superfluidity far from equilibrium. The local version of TDDFT is particularly well suited for leadership-class computersof hybrid (CPU+GPU) architecture. Using the most powerful supercomputers, we are currently able to study a real-time 3D dynamics without any symmetry restrictions evolving up to hundreds of thousands of superfluid fermions. It represents a true qualitative leap in quantum simulations of superfluid systems, allowing us to make quantitative predictions and reach limits inaccessible in laboratories. During the talk I will review several applications and results concerning nuclear collisions and induced fission, dynamics of nuclear matter in neutron stars, dynamics of topological excitations and exotic structures in ultracold atomic clouds.
