I’m a software engineer and consultant I’d be interested in testing and developing this for Travis.
I think ideally you’d start with something like gpu: true in the travis config, and go from there. It should be possible to work on both linux and macos, but even just linux support would be awesome (and probably the priority).
We do in fact have some limited GPU testing available, but only on private repositories. I’ll see if I can get some more information publicly available but for the meantime, I’d suggest shooting an email to success@travis-ci.com so we can look into what needs to be done for you to enable it, as well as any potential costs.
For the moment, this feature is on hold as there are changes required to the implementation. You can keep an eye on our Community Forum, Blog, Changelog and Twitter handles for updates on when this will be ready for use.
