@sdarwin I added a workflow with runs-on: gpu-runner-1, but the job doesn't seem to be getting picked up. Is there something else that I need to add?

There may be more than one blocker.

The first step: enabling a larger GitHub actions runner requires being an Owner of an organization, and then configuring billing and spending limits. I'm not able to do this on boostorg so gpu-runner-1 exists in cppalliance.

We might explore the options of setting up billing in boostorg. However, since the effectiveness of the gpu tests is still unknown, how about creating a repository in cppalliance ?

I'll try a similar PR on cppalliance/decimal since the concept is the same.
