Andreas Schmelz: Optimizing Molecular Dynamics Simulations Using One-Sided MPI-Communication


Andreas Molzer: Optimization of a solver for the shallow water equations for heterogeneous GPU architectures

This work builds on past endeavours to implement an augmented Riemann solver for the Shallow Water Equations. The solver itself is based on work by D.L George and will be included without many changes. This paper deals with general concepts for implementing optimized algorithms for GPGPUs and show their application by constructing a better implementation of the previous \cuda solver code. The SWE-X10 project, aiming at providing a highly scalable simulation on heterogeneous systems is used as a framework. Additionally to dealing with \cuda, some general improvements are implemented in the surrounding project to bring it closer to its goal. Lastly, the solver for graphics cards is examined in the context of the project by finding generally good scalability properties.
