[debug] voronoi is slow
When compiled in debug mode, voronoi can take a long time to execute.
- native 733 seconds https://zivgitlab.uni-muenster.de/HPC2SE-Project/pacxx-samples/-/jobs/10016
- cuda 998 seconds https://zivgitlab.uni-muenster.de/HPC2SE-Project/pacxx-samples/-/jobs/10389
Find out why and preferably fix it (e.g. by reducing the problem size), or document in voronoi/CMakeLists.txt
when setting the slow label why this is the case.
