Multicore-aware parallel temporal blocking of stencil codes for shared and distributed memory
Markus Wittmann, Georg Hager, Gerhard Wellein
New algorithms and optimization techniques are needed to balance the accelerating trend towards bandwidth-starved multicore chips. It is well known that the performance of stencil…
Multi-core architectures: Complexities of performance prediction and the impact of cache topology
Jan Treibig, Georg Hager, Gerhard Wellein
The balance metric is a simple approach to estimate the performance of bandwidth-limited loop kernels. However, applying the method to in-cache situations and modern multi-core arc…
Numerical approaches to time evolution of complex quantum systems
Holger Fehske, Jens Schleede, Gerald Schubert +3
We examine several numerical techniques for the calculation of the dynamics of quantum systems. In particular, we single out an iterative method which is based on expanding the tim…
