NVIDIA H100 80GB PCIe Hands on CFD Simulation

We take the NVIDIA H100 80GB PCIe card for a spin with a FluidX3D CFD simulation tool to see how the new card performs

This week for SC22, we have a fun treat. We jumped on a NVIDIA H100 80GB PCIe GPU. This was still in an Ice Lake Intel Xeon server, but we had a few minutes, and just wanted to poke around. While this was happening, Moritz Lehmann who has an OpenCL CFD application expressed interest, and we ran his CFD codes to see how they compared to the previous version.

If you want to see the types of simulations this OpenCL lattice Boltzmann CFD software does, you can see an example here with the Space Shuttle simulation:

Still, we wanted to highlight a cool project and get them some data on a new card while also showing our readers the jump from A100 to H100 performance. Also, interesting on this is that the H100 is roughly double the performance of Moritz’s single GCD MI250 runs.
