| | 5 | We have 295,867 sus available for our account. Jobs submitted to normal queue. First batch on 512 cpus for 15 hours. Took a sampling of the four times by using {{{ls -ltr}}} (beginning, the middle, two at the end) between the selected chombos. |

| | 7 | $\overline{t}_{hydro} \approx 21.5 \text{min}$ |
| | 8 | [[br]] |
| | 9 | $\overline{t}_{mhd} \approx 36.5 \text{min}$ |
| | 10 | |
| | 11 | We have 1,440 minutes in a day. So we can calculate out the average rate: |
| | 12 | |
| | 13 | $\overline{r}_{hydro} = \frac{1,440 \text{min}}{\overline{t}_{hydro}} \approx 67 \frac{\text{frame}}{\text{day}}$ |
| | 14 | [[br]] |
| | 15 | $\overline{r}_{mhd} = \frac{1,440 \text{min}}{\overline{t}_{mhd}} \approx 40 \frac{\text{frame}}{\text{day}}$ |
| | 16 | |
| | 17 | For both of these runs we want to have 200 frames. Taking the difference from what we can see from the first rows of our jobs listed below, that means we have 177 frames left for the hydro case, and 182 for the mhd case. Using our average rates from above, that means it will take approximately 3 days to finish the hydro run, and 5 days to finish the mhd run (based on these values). There are 72 hours in 3 days and 120 hours in 5 days. One can see I'll be under the SU limit for the following cpu*hrs. |

| | 19 | == 512 cores == |
| | 20 | |
| | 21 | For the hydro case: $72 \text{hrs} * 512 \text{cores} = 36,864 \text{cpu hrs}$ |
| | 22 | |
| | 23 | For the hydro case: $120 \text{hrs} * 512 \text{cores} = 61,440 \text{cpu hrs}$ |

| | 28 | |
| | 29 | * Note rates would change based on these many cores (increase)... so this is kind of shotty to say, as it uses times pulled from jobs run on 512 cores. |
| | 30 | * Next restart, I think I will run them on 1024 cores for 5 hours and get a more exact estimate. It may be cheaper to consider this? |
| | 31 | |
| | 32 | For the hydro case: $72 \text{hrs} * 512 \text{cores} = 73,728 \text{cpu hrs}$ |
| | 33 | |
