Abstract:
In this presentation, we will demonstrate that heterogeneous computing with processors of different architectures used concurrently for different algorithms may give both good scalability and efficiency for large-scale simulation of complex flow and transport processes. Meso-scale models are introduced to consider the sub-grid-scale structures in continuum methods and coarse-grained discrete methods. Highly parallel codes for continuum-based finite volume method, discrete element method and lattice Boltzmann method are implemented on the central processing units (CPUs), many-integrated cores (MICs) and graphics processing units (GPUs), respectively. Quasi-realtime simulations of lab-scale systems with particle-scale resolution are thus obtained and virtual-reality (VR) style simulations are under development. Some preliminary results can be found in our recent publications [1-6] and the most recent developments will be introduced in this presentation.
