CacheQuery: Learning Replacement Policies from Hardware Caches
Thu 18 Jun 2020 16:40 - 17:00 at PLDI Research Papers live stream - Synthesis II Chair(s): Phitchaya Mangpo Phothilimthana
We show how to infer deterministic cache replacement policies using off-the-shelf automata learning and program synthesis techniques. For this, we construct and chain two abstractions that expose the cache replacement policy of any set in the cache hierarchy as a membership oracle to the learning algorithm, based on timing measurements on a silicon CPU. Our experiments demonstrate an advantage in scope and scalability over prior art and uncover two previously undocumented cache replacement policies.
