For my student research project (Studienarbeit), I worked on the parallelisation of the precomputation for Highway Node Routing. I did this project at the Institute for Theoretical Computer Science, Algorithmics II at the Universität Karlsruhe (TH). My supervisors were Johannes Singler and Dominik Schultes.
I parallelized the existing C++ code using OpenMP and the libstdc++ parallel mode.
