Description
Several test case generators are defined in cpp/tests/neighbors/ann_ivf_pq.cuh but are never used in any of the test instantiation files. Therefore it looks like these test scenarios are never exercised in CI.
- special_cases()
- var_n_probes()
- big_dims_small_lut()
Current Test Instantiations
Looking at the test files in cpp/tests/neighbors/ann_ivf_pq/:
test_float_int64_t.cu:
INSTANTIATE(f32_f32_i64,
defaults() + small_dims() + big_dims_moderate_lut() + enum_variety_l2() +
enum_variety_l2sqrt() + enum_variety_ip() + enum_variety_cosine());

- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start with the test case generators in cpp/tests/neighbors/ann_ivf_pq.cuh and compare them with the instantiations in cpp/tests/neighbors/ann_ivf_pq/. Check the existing test files, including test_float_int64_t.cu, then run the IVF-PQ tests. Done means special_cases(), var_n_probes(), and big_dims_small_lut() are instantiated and exercised in CI.
