High-performance computing for climate change impact studies with the Pasture Simulation model.

Highlights: [•] We simulate grassland processes over large areas for climate change impact studies. [•] We parallelize simulations with pixel-based Pasture Simulation model (PaSim). [•] We perform simulations with 8×8km resolution for metropolitan France (∼10,000pixels). [•] We report 25h (speedup of 200) for the simulation on a 200-processor cluster. [ABSTRACT FROM AUTHOR]
