Host: 

Parallab is the unit for High Performance Computing at the University of Bergen and operates the universities supercomputer facilities and other e-infrastructures. The group conducts research and development in scientific computing, engineering, Grid- and other e-infrastructures.

In this presentation we introduce Parallab and its activities in scientific computing. Specialfocus will be on computational results in miscible displacement porous media flow. These processes can be described by nonlinear partial differential equations. We will address challenges in their numerical treatment and discuss software development as well as numerical solutions strategies. Secondly, we show how results from numerical bifurcation analysis can help to understand the structure of the nonlinear solutions. Finally, we apply statistical methods in order to derive practically relevant results from the nonlinear, instable dynamics. It turns out that large
compute- and storage infrastructures are required to efficiently obtain these types of results.
