SUMMARY StochKit2 is the first major upgrade of the popular StochKit stochastic simulation software package. StochKit2 provides highly efficient implementations of several variants of Gillespie's stochastic simulation algorithm (SSA), and tau-leaping with automatic step size selection. StochKit2 features include automatic selection of the optimal SSA method(More)
Simulation of the nonlinear mechanical response of materials with explicit representation of microstructural features is extremely challenging. These models typically involve a very large number of degrees of freedom, and are prone to convergence difficulties when searching for roots to nonlinear equilibrium equations. We focus on an idealized material(More)
In order to perform high-performance Monte Carlo simulations of fracture in certain composite materials, we needed fast methods for generating deterministic random numbers. We made several design choices, and due to the fact that the entire simulation was to be done on both CPUs and GPUs, we designed new methods for fast implementation of the AES in the ECB(More)
