Now DARTS can be run completely on GPU device. With a gaming-class GPU card (GeForce RTX 2080 Ti, ~€1000) pluggable to a regular desktop you can run full SPE10 for less than 3 minutes. Not bad for the research open-source simulator, thanks to TOTAL for sponsoring the project.

Woops Performance of different DARTS components at CPU and GPU (mind log scale in time).
