Table 3:
Estimated resource requirements for cerebral geometry using APR vs eFSI. At this grid spacing and resolution ratio, the total estimated memory needed is 5 orders of magnitude smaller using APR. Thus an APR simulation can fit on a single node while the eFSI model would be unable to fit on a single system.
| Model | Δx (μm) | Fluid Pts | Fluid Memory | Num RBCs | RBC Memory |
|---|---|---|---|---|---|
| APR (window) | 0.75 | 1.76 × 107 | 7.2 GB | 2.9 × 104 | 1.48 GB |
| APR (bulk) | 15 | 1.58 × 108 | 64.4 GB | - | 0 |
| eFSI | 0.75 | 1.47 × 1013 | 6.0 PB | 6.3 × 1010 | 3.2 PB |
