Will the latest CUDA 12.01 work? about gpu-raytracer HOT 5 OPEN

I have not picked up development, and am instead working on my own pathtracer(on my github), which I mention because without Zuen, I wouldnt have had the drive to continue it a year ago,
Sorry, but I am not sure if this will work with the latest cuda, havent used it in awhile sorry

Hello,

I have been able to compile it up with CUDA 11.0.2 and it seems to initially work run by giving me the help screen with:

Pathtracer.exe --help

I did see some mention of using the Mitsuba examples but not sure how to use them:

https://github.com/jan-van-bergen/Mitsuba-Scenes

Now the question is how to interactively render the images that you have on the Github site?

I am wondering what a typical CLI invocation looks like.

Any help that you could provide would be appreciated.
Thanks agian.

Nope, I was mistaken as it will build apparently, but I get a runtime error for both the Release and Debug versions:

Loaded BVH 'Data/sponza/models/sponza_344.obj.bvh' from disk

NVRTC output:
nvrtc: error: invalid value for --gpu-architecture (-arch)

I am not sure of the error tbh, its been a year since I launched it, sorry

Hi @lonnietc , in Device/CUDAContext.cpp, at CUDAContext::init(), the best compute capability (best_compute_capability) is determined and this variable is passed to NVRTC's --gpu-architecture command line argument as compute_XX, where XX is this compute capability. However, this might not match with an actual compute (minor) version (you can find the accepted command line arguments in the user guide, page 17).

It's likely that the code is passing this incorrect argument to NVRTC, so the best option is to round down this best_compute_capability to the nearest major version (e.g. non-existent version 86 becomes existing version 80).
