Gradient reconstruction in a legacy CFD application using task-based programming models

We investigated different runtime systems, namely StarPU and PaRSEC and their use in a legacy CFD code from EDF R&D. We assessed both runtimes in terms of performance, ease of implementation and various others criterion such as maintainability, documentation and team activity. By experimenting these solutions out of classical linear algebra problems, we push them out of their comfort zone into the common issues seen in Computational Fluid Dynamics codes with unstructured meshes [30].
