About mesh generation rate of HXT algorithm
Hello, Dear developer.
I am interested in the HXT algorithm and want to work on it. It's an efficient algorithm, much faster than other parallel algorithms. But what bothered me was that I could not reach the generation rate presentation in the paper《One machine, one minute, three billion tetrahedra》. I used a simple box geometry model(100100100) to test ,the generate rate about 5 million tetrahedra per second, only aout 1/10 of the rate of presentation in the paper.
I don't know if I did something wrong that might affect the rate,or it's just the normal speed ?
- Hardware information :24-core Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz,251GB of RAM.
- Run command options: gmsh ./box.geo -3 -nt 24 -clscale 0.03 -algo hxt
- Gmsh version: Gmsh 4.5.2
I put the run log in the attach file.output.txt
