Concurrency race & deadlock repair

Concurrency race & deadlock repair is an OpenEnv-compatible reinforcement learning environment in our Software & Systems catalog. An agent acts through the tools below, and a deterministic verifier scores every episode, so the reward can be used for GRPO or other RLVR post-training.

Task and verification

Diagnose and repair subtle data races, atomicity violations, and lock deadlocks in multithreaded systems under deterministic thread-interleaving schedulers.

Tools and runtime

ThreadSanitizer (TSan) + Shuttle + rr deterministic replay

OPENENV / TSAN

Plan a training run

Check the environment’s availability, compatible models and compute in Studio. A catalog entry does not guarantee that hosted training is enabled for your workspace.
