Notes
- In surface refinement there is a missing timer for removing small edges, it is included in the total time
- values of 0.0 indicate number smaller than 1e-2
- quality data is similar with above
- Previous Data below, number of elemnts fixed, recompiled with gcc-7 (above) reduced the time difference for reconstruct between 8,12,24 cores

Notes
- In surface refinement there is a missing timer for removing small edges, it is included in the total time
- values of 0.0 indicate number smaller than 1e-2
- quality data is similar with above
