AcceleRad installation error on Renderfarm

Hi all,

For large scale simulations, we are trying to install AcceleRad on our faculty Renderfarm. Unfortunately we are running into errors when testing the AcceleRad installation. We are suspecting it has to do with Optix compatibility (also notice that we use TCC). Could someone advise us on how to proceed?

GPU’s on the renderfarm:
2x NVIDIA A40 GPU
Driver-version 518.03
CUDA-version 11.7

Hereby also the nvidia-smi report:

Hi @JobdeVogel,

This is not a Ladybug issue, so you’d be better off posting on the Radiance discourse.

In any case, the error is just a generic error that Accelerad could not create on OptiX context. It’s been a while since anyone has brought this up, but I recall from some time ago that this happened in render farm settings. I’m not sure how TCC would be involved, as I’ve used Accelerad in TCC mode before.

Thanks for the quick response! I will publish the question again asap on the Radiance discourse. I will also take another look at our Renderfarm settings to see if we can find anything related to the OptiX context.
