Table 4.
Summary of the details and parallelization methods in each code, an estimation of the CPUh to calculate collapse and post-bounce until 50 ms for models X95-PG (ELEPHANT, FLASH, and SPHYNX) and model G95-MSG (fGR1), and maximal spatial resolution at t = 50 ms.
| Code | Type | Discretization | # Fluid elements | Parallelization | CPUh | Max. resolution |
|---|---|---|---|---|---|---|
| (m) | ||||||
| ELEPHANT | Eulerian | Cartesian mesh | 2.1 × 108 | MPI+GPU | 79 000 | 1000 |
| FLASH | Eulerian | AMR | 1.9 × 107 | MPI+GPU | 117 000 | 488 |
| SPHYNX | Lagrangian | SPH particles | 2 × 105 | MPI+OpenMP | 13 000 | 477 |
| fGR1 | Eulerian | Nested mesh | 3.5 × 106 | MPI | 245 000 | 458 |
