one will be recording and editing raw cinema quality footage at qualities like 12k (and higher if they even bother inventing that - there's not really a noticeable improvement in quality past 8k unless you're zooming in - and that's assuming you even manage to find a screen that can put something that high quality up)

Computational fluid dynamics (CFD) simulations can only partially be done in parallel, but each simulation step requires predictor/error regularization which is a serial aggregate step. This step is the bottle neck when you try to check if everything in the total simulation adds up correctly, the memory requirement isn’t huge, but it has to happen quickly and all in one place.
