Table 1.
Computational time of each method for the section of 67P/CG surface presented in Fig. 8.
| Computation method | Time (h) |
|---|---|
| M1 | 0.2 |
| M2 | 0.2 |
| M3-Linear(64), (256) | 37, 540 |
| M3-R2(64), (256) | 30, 463 |
| M4 | 333 |
| Combined | 25 |
Notes. The reported value is the output of the time command of Unix. The (64) and (256) indicate number of sub-facets used for the M3 methods. The timing was done when running on a single processor. The execution times scales well (nearly linearly) with the number of cores employed in the calculations since each facet-pair is independent from each other.
