Report your benchmark results here!

You are welcome to report your benchmark results for the FP32/FP16S/FP16C accuracy levels here.
Especially numbers for AMD GPUs are desired for GCN/RDNA/RDNA2 architectures.
Thank you!

I'd love to add to the benchmarks list. I've got two questions:

1. I want to benchmark a dual Epyc system (so specifically the CPUs actually). How would I do that (under Windows, but Linux would also be fine), if I have a GPU installed? It always automatically detects the GPU when running the benchmark “releases”.
2. How to post the benchmarks? Just copy the console output in here?

Cheers!

Hi ibonito1,

OpenCL support on EPYC CPUs is a bit difficult as these are not officially supported by AMD. Being x86-64, they should work with the Intel OpenCL CPU Runtime though, or alternatively with POCL. Fingers crossed!
To run on a specific device, in the console run ./FluidX3D.exe 2 (on Linux) or FluidX3D.exe 2 (on Windows), to select device with ID 2 for example.
You can just copy the console output here.

C-Dub2022 thank you very much for the RX 580 benchmark! If you can post the FP16S and FP16C benchmarks as well, I'll add them to the readme!

[C-Dub2022]

Hopefully this is helpful. Let me know if there is anything else I can do.

Could you please tell me how to open the visualized interface of the flow domain as you said in the readme file? You said input the 2 can turn on the velocity field, but it does not work in the benchmark case. How can I generate pictures like you prensent on twitter ?

[ProjectPhysX]

Hi dongwang22,

thanks for the benchmark! For the visual interface, uncomment #define WINDOWS_GRAPHICS and comment #define BENCHMARK in src/defines.hpp, and uncomment for example the Taylor-Green setup in src/setup.cpp. Then compile and you should see the graphical interface where you can toggle rendering modes with keys 1/2/3/4. To generate videos, see the other setups: basically make a C++ loop and repeatedly do some LBM time steps and render images with the corresponding methods of the LBM class.

Regards,
Moritz

I tried a 6900XT, but the score is lower than anticipated. The max bandwidth seems to be limited to 300GB/s, although GPUZ says it's connected via PCIe 4.0 16x and should top out at 512GB/s. The GPU clock is at 2540MHz and the memory clock at 2000MHz. GPU and memory controller loads are at 100%.

With the 3D Taylor-Green model and FP32/FP16S, the MLUPs/s and the bandwidth go through the roof. I'll try some other models, too. FP32/FP32 goes up to 2400 MLUPs/s and 370GB/s, with FP32/FP16C it's 9000 MLUPs/s and 700GB/s.
