Automating Heterogeneous Parallelism in Numerical Differential Equations
… investigated. Parallelism for sufficiently large stiff ODEs is traditionally linked to the parallelization of the matrix factorization stage. However, these methods still need to overcome the threading overhead for ODEs having less than approximately 200 states. We propose implementing …

Exponential integrators: tensor structured problems and applications
The solution of stiff systems of Ordinary Differential Equations (ODEs), that typically arise after spatial discretization of many important evolutionary Partial Differential Equations (PDEs), constitutes a topic of wide interest in numerical analysis. A prominent way to numerically integrate such …
