Pipelined Iterative Solvers with Kernel Fusion for Graphics Processing Units
Karl Rupp, Josef Weinbub, Ansgar Jüngel +1
We revisit the implementation of iterative solvers on discrete graphics processing units and demonstrate the benefit of implementations using extensive kernel fusion for pipelined…
Performance Portability Study of Linear Algebra Kernels in OpenCL
Karl Rupp, Philippe Tillet, Florian Rudolf +3
The performance portability of OpenCL kernel implementations for common memory bandwidth limited linear algebra operations across different hardware generations of the same vendor…
Boundedness of weak solutions to cross-diffusion systems from population dynamics
Ansgar Jüngel, Nicola Zamponi
The global-in-time existence of nonnegative bounded weak solutions to a class of cross-diffusion systems for two population species is proved. The diffusivities are assumed to depe…
A degenerate fourth-order parabolic equation modeling Bose-Einstein condensation. Part II: Finite-time blow-up
Ansgar Jüngel, Michael Winkler
A degenerate fourth-order parabolic equation modeling condensation phenomena related to Bose-Einstein particles is analyzed. The model is a Fokker-Planck-type approximation of the…
A degenerate fourth-order parabolic equation modeling Bose-Einstein condensation. Part I: Local existence of solutions
Ansgar Jüngel, Michael Winkler
A degenerate fourth-order parabolic equation modeling condensation phenomena related to Bose-Einstein particles is analyzed. The model is a Fokker-Planck-type approximation of the…
