Numba has a CUDA_LOW_OCCUPANCY_WARNINGS that raises a warning whenever a binary predicate is called with a small input size (ie for testing). I added NUMBA_CUDA_LOW_OCCUPANCY_WARNINGS=0 to my environment which reduced the number of test errors from 984 to 71.

What binary predicates use Numba?

[thomcom]

Nothing in the binary predicates directly uses numba. My only guess is that cudf functionality is being used that produces that warning, but haven't come up with a way of tracking down exactly what is emitting the warnings yet.

[harrism]

I don't feel comfortable suppressing warnings without understanding the cause.
