SpaceX Merlin (& Raptor ) Engine R&D, GPU-Powered

Adam Lichtl and Stephen Jones of SpaceX talk about simultating combustion in very large rocket engines. They use graphics processing units (GPUs) from nVidia for this task. While not directly mentioning Raptor, the limits they are pushing are clearly the result of the need to understand ever larger combustion systems, and they wouldn't be pushing as hard if this was only for the Merlin engine, which is already operational as well as reliable.

(I have watched this presentation several times and found their posting to be unreliable and slow especially when skipping between parts, that's why I have re-posted it)
