Notes
- according to Mike's email mesh should be around 100k vertices
- Metric Input Data available at https://github.com/UGAWG/parallel-adapt-results
- Input surface is the coase mesh available at https://github.com/UGAWG/solution-adapt-cases
- The experiments performed on a DELL workstation with Linux Red Hat Enterprise, 24 hardware cores Intel® Xeon® CPU E5-2697v2@2.70 GHz, and 757 GB RAM
- Memory is measured at the end of Mesh refinement and thus it may reach a slightly higher value before the point of measurement
