Development of a parallel multi-term Boltzmann solver using the Qubus framework — •Christopher Hinz1, 2, Markus Becker2, Detlef Loffhagen2, and Michael Bonitz11ITAP, Christian-Albrechts-Universität zu Kiel, Leibnizstr. 15, 24098 Kiel — 2INP Greifswald, Felix-Hausdorff-Str. 2, 17489 Greifswald

Electron transport and rate coefficients required by hydrodynamic plasma models are frequently obtained by solving the stationary and homogeneous Boltzmann equation of the electrons. The present contribution reports on the status of the implementation of such a Boltzmann solver by means of the parallelization framework Qubus [1]. Qubus particularly assists in the development of parallel codes for multiple platforms without compromising the ability to easily adapt the code to new requirements. The considered solution procedure is based on a multi-term expansion of the electron velocity distribution function in Legendre polynomials [2]. The speedup of the solution procedure provided by Qubus finally enables the direct coupling of the kinetic equation with hydrodynamic plasma models.
