I have just finished studying physics at Leipzig University and concluded my master thesis on the evaporation-condensation transition of a Lennard-Jones fluid. During my studies I have spent quite some time implementing and working with Monte Carlo techniques, most recently in the grand canonical ensemble. So far, my simulations were written in C++ relying on MPI for parallelization. On my part-time job I have worked on a GPU-optimized version of an atmospheric model in OpenCL. The time integration is done utilizing multirate infinitesimal step methods, allowing efficient computation without divergence damping at the price of a somewhat larger memory footprint.
