The SPICE2 model has been parallelised with the exception of the Poisson equation solver, which considerably slows down the simulations. It is now being upgraded to a parallelised version to be efficient enough to perform more demanding tasks like the ITER tokamak baseline scenario edge plasma, which is characterized by very high density (up to 1020 m-3) and low temperature (1–2 eV).This leads to extremely small Debye length (10-7 m) and enormous grids (thousands of cells in each direction).This in combination with a shallow magnetic field inclination (1 – 2 deg.)results in simulations taking several months to compute. Performance and scaling are compared for different solvers using the Helios IFERC supercomputer in order to choose the optimal candidate for specific conditions.
