@christopherbate Here are the builder-side changes to allow the GPU allocator to be set up. We probably do not need this and will only be required for runtime allocations.

It is unclear how to manage the lifetime. Should I use unique_ptr instead of the raw pointer?

I might add this in a separate PR.

Temporarily remove it to simplify testing.
