Motivated by the success of iterative decoding algorithms, we consider the general problem of making inferences based on observed data, which are known a-priori to satisfy multiple sets of constraints. We consider relative entropy minimisation and an iterative algorithm for its calculation, which exploits the presence of multiple constraints. Using these principles, optimal iterative decoders, ...

Various self-consistent semiconductor device equations, such as drift diffusion, hydrodynamic and Boltzmann transport equations require solution of a multi-dimensional Poisson’s equation that describes the potential distribution in the device for a specified doping profile. In this paper, a three-dimensional semiconductor nonlinear Poisson’s equation is solved numerically with finite volume and...

Solving the eikonal equation allows to compute a monotone front propagation of anisotropic nature and is thus a widely applied technique in different areas of science and engineering. Various methods are available out of which only a subset is suitable for shared-memory parallelization, which is the key focus of this analysis. We evaluate three different approaches, those being the recently dev...
