Validation and Performances

Validation

HySoP has been validated throughout published and peer reviewed papers (see Bibliography) in several cases either for academic test-cases or benchmarks.

• Taylor-Green vortex: [1] and dedicated example (https://gricad-gitlab.univ-grenoble-alpes.fr/particle_methods/hysop/-/tree/master/hysop_examples/examples/taylor_green)

• Flow past a sphere: [2]

• Double-diffusive sedimentation: [3]

• Dissolution of a porous media with two-scale porosity: [4]

Performances

Performances can be investigated in two distinct ways:

• Low-level (kernel level) computations

• Application level overall scalability

Concerning kernel level performances, we implement a automatic fine tuning of implementation parameters thanks to OpenCL code generation. See Code generation and autotuning for details and [5] for results.

Overall performance study in parallel cases have been done in [6]. These results are suite out-of-date and will be renewed in the near future.
