32 AMD Instinct MI210 accelerators worked for 33 hours
The other day, physicist Moritz Lehmann, also known as the author of FluidX3D with the pseudonym @ProjectPhysX, conducted one of the largest simulations in the field of computational fluid dynamics (Computational Fluid Dynamics, CFD). He simulated the landing process of the Concorde aircraft at a speed of 300 km / h with 40 billion cells.
A second of Concorde landing takes up 285 TB of memory
For the simulation process, a system of 32 AMD Instinct MI210 accelerators with a total of 2 TB of memory was used. And despite all their power, just one second of the simulation counted for 33 hours.
According to the author, each frame of the simulation takes up 475 GB of data, and the full simulation took up 285 TB.
Lehmann claims that such a simulation would take years on commercial CFD systems, but FluidX3D does it in a weekend.
