The poor Phd student felt so embarassed by his professor he already appologized:
"Thanks! Sorry for the high-pitched expression on Twitter.. In the paper, we are much careful about the wording. "
I read part of the paper regarding Navier Stokes, and they trying to simulate a fluid in 2D on a 64x64 grid.
How fast one iteration step takes, seems to be 0.005s as quoted.
My GPU simulator does simulate 304x304x304 (and also render it at the same time in 4K) at 160 FPS on a 3090
So 0,00625s per iteration, without the rendering it would at least also be 0.005s for the simulation iteration.
The difference we both do 0.005s per iteration but this NN method does it for 64x64 and my method does it for 304x304x304
Or my method is 304^3 / 64^2 = 7000x times faster compared to this NN method.
Or 7000000x times faster to what the NN method compares itself with.
Now I expect to get here 7000 times more likes as the post before
