Code made 416 large steps with time per step varying from 4min to 1.7hrs. The total estimated cpu is 5M cpu hours, which is about two weeks of wall-clock. It took about 2months to complete the run because the system was unstable - we were using it as it was build and de-bugged. |
| Resolution |
Force resolution (one cell size) at the highest refinement level was 1 kpc/h.
Mass resolution (mass of a particle) is 1.3e8 Msun/h
Time-step at the lowest resolution : da = 2.e-3 for a<0.80 and da=3e-3 for a> 0.80
Maximum number of steps: 400000
