Table 1
Computational cost of simultaneous emulation on a batch of ten samples (each sample being made of a Q and a U polarization map) as a function of map resolution, Nside.
| Nside | Memory [GB] | GPU hrs |
|---|---|---|
| 16 | 0.419 | 0.12 |
| 32 | 1.512 | 0.25 |
| 64 | 6.151 | 0.46 |
| 128 | 25.93 | 1.11 |
| 256 | 95.96 | 2.17 |
| 512 | 376.7 | 4.5 |
| 1024 | 1478 | 9.3 |
| 2048 | 5804 | 19.3 |
Notes. The table shows the peak memory usage in GB and speed in GPU hours for each resolution level, obtained using double precision floats on an NVIDIA A100 64 GB GPU. Values of up to Nside = 128 were measured, while the ones at a higher resolution were obtained extrapolating the trend of the measured points (see Section 4.2 for details).
