"""Entry point for the PORR benchmark suite.

Runs ``tests.py``, which compares this project's Richardson implementations
(sequential, threads, processes, distributed arrays) against numpy's direct
solver over a range of matrix sizes.

The suite is heavy at the largest sizes it parametrises; ``../run.sh`` narrows
the default selection via ``PYTEST_ADDOPTS`` and says there how to widen it.
