Requirements

• WebGL supported browser

• Nvidia GPU and recent drivers

-- On Hybrid systems/ notebooks with multiple GPUs - Refer https://alteredqualia.com/texts/optimus/

-- On Tegra systems, Chrome seems to be using SwiftShader by default, so perform the manual step of identification (#manual)

How to get compute capability

Browser

Browse to this link - https://gpupowered.org/mygpu/

The compute information will be displayed in the same page

Manually

Obtain the name of the GPU by running below command on command line

nvidia-smi --query-gpu=name --format=csv

Then use this json file to find the compute capability

https://github.com/prabindh/mygpu/blob/main/mygpu.json

Using this information

In Makefiles

Enter only the compute_xx string obtained above, in the arch= and code= fields below

ARCH= -gencode arch=compute_xx,code=compute_xx
$(OBJDIR)%.o: %.cu $(DEPS)
    $(NVCC) $(ARCH) $(COMMON) --compiler-options "$(CFLAGS)" -c $< -o $@

In Visual Studio (For CUDA Runtime Project Type only)

Enter the complete string obtained above, in this field

Configuration Properties --> CUDA C/C++ --> Device --> Code Generation --> compute_xx,sm_xx
