I've been trying to get AIR working in PETSc. I realized that my first task is to come up with a test/example that demonstrates a correct AIR implementation, and I think this example does that. (I modeled it after the example in pyamg). It converges in one iteration. Switching to a 0 restriction (transpose of interpolation operator), the example takes multiple iterations.
I think having this example in the hypre repository will help people curious about AIR and curious to try hypre's implementation.
@bensworth figure it's worth pinging you here. I think armed with this hypre-only example I'll be able to determine very quickly any issues with the corresponding PETSc AIR wrapper.
