Optix 7.2 is not compatible with 50 series GPUs

[hsmmoj]

Hi,
I'm encountering issues trying to run the LiDAR module on a newer GPU (50-series). Here's what I've tried:
Attempt 1: OptiX 7.2

Build: Successful
Runtime: CUDA error 999
Note: The module previously worked fine with my older GPU

Attempt 2: Higher OptiX version

Build: Failed with the following error:
error: 'optixModuleCreateFromPTX' was not declared in this scope; did you mean 'optixModuleCreate'?
213 | CHECK_OPTIX(optixModuleCreateFromPTX(context, &moduleCompileOptions, &pipelineCompileOptions, optixProgramsPtx,
| ^~~~~~~~~~~~~~~~~~~~~~~~

Question: Is there a way to get the LiDAR module working with 50-series GPUs? Any guidance on compatible OptiX versions or necessary code modifications would be appreciated.
Thanks!

Hi @hsmmoj
Thank you for reporting this issue.

To help me investigate and resolve the problem, could you please provide the following details:

1. What is your NVIDIA driver version (nvidia-smi command)?
2. Which version of the RobotecGPULidar project are you building? The latest develop branch or a specific tagged version?
3. What version of the CUDA Toolkit are you using (nvcc --version command)?

Hi. Thank you for your response.

1. Driver Version: 580.95.05
2. Develop
3. I am using the Docker image "nvidia/cuda:13.0.0-cudnn-devel-ubuntu22.04".

Thanks.

Could you try to compile with the CMAKE_CUDA_ARCHITECTURES definition in CMakeLists removed (this line)? OptiX 7.2 should work fine.
