It only takes 32 AMD GPUs and 33 hours to run a 40 billion cell simulation of the Concorde supersonic plane

Complex fluid simulations are complex.

Thanks to OpenCL , ProjectPhysX says"FluidX3D works out-of-the-box with 32-GPU scaling", which made the whole process a lot easier with no code changes required on their part.

The purpose of the test was to get an idea of how well the"newly implemented free-slip boundaries" are working in the simulation. These are meant to make the model more accurate than previous implementations of so-called"no-slip boundaries". In the comments, ProjectPhysX gives a little explanation of the difference between the two:"No-slip enforces that the fluid velocity at the wall is the same as the wall velocity. Walls 'drag along' the fluid, causing more friction. Free-slip means the fluid velocity perpendicular to the wall is not restricted, the fluid can freely glide along the wall without friction."

All in all, it's a very exciting use of the GigaIO SuperNODE, and one that I'm sure has a number of exciting implications for the future of aviation. The better we can simulate these things, the less Icarus-style experiments we have to do in the real world.Sign up to get the best content of the week, and great gaming deals, as picked by the editors.
