Supported CUDA versions


The OptiX 5.1 release notes states that CUDA 7.0, 7.5, 8.0 and 9.0 are supported. I’m going to be playing around with OptiX and Tensorflow on the same machine and our current Tensorflow setup uses CUDA 9.1. Is there any chance that OptiX supports CUDA 9.1 or maybe even 9.2? Or are there breaking changes between in those minor updates?


CUDA 9.1 and 9.2 should basically work as well, as long as they don’t generate code the OptiX PTX parser or compiler doesn’t like.
I have not tried CUDA 9.2, yet, and there have been two reports on this forum where using CUDA 9.1 did run into some problems which did not occur with 9.0.
Just give it a try.

Alrighty. I’ll be your guinea pig. :)

I was mostly worried that the OptiX compiler would see that the code came from a newer compiler and not even try to parse it.
