Model-guided Performance Analysis of the Sparse Matrix-Matrix Multiplication
Tobias Scharpff, Klaus Iglberger, Georg Hager +1
Achieving high efficiency with numerical kernels for sparse matrices is of utmost importance, since they are part of many simulation codes and tend to use most of the available com…
All good things come in threes - Three beads learn to swim with lattice Boltzmann and a rigid body solver
Kristina Pickl, Jan Götz, Klaus Iglberger +4
We simulate the self-propulsion of devices in a fluid in the regime of low Reynolds numbers. Each device consists of three bodies (spheres or capsules) connected with two damped ha…
Expression Templates Revisited: A Performance Analysis of the Current ET Methodology
Klaus Iglberger, Georg Hager, Jan Treibig +1
In the last decade, Expression Templates (ET) have gained a reputation as an efficient performance optimization tool for C++ codes. This reputation builds on several ET-based linea…
