Overview
What this challenge is about.
Build a lock-free MPMC queue in C++20 for a trading backend and benchmark it against alternatives. Earn a verifiable certificate.
The scenario
The trading firm (latency-sensitive, 3-person platform-engineering team) considers every 100ns shaved off the queue a directly compounding edge.
The Brief
What you'll do, and what you'll demonstrate.
Implement a lock-free Vyukov MPMC queue with provable correctness and beat moodycamel by >30 percent on the firm's trading-tech benchmark scenarios.
Earning criteria — what you'll demonstrate
- Implement a bounded lock-free MPMC queue with correct memory orderings
- Use TSan + interleaving-exploration tools to validate concurrency
- Pad data structures to eliminate false sharing on hot fields
- Benchmark with statistical rigor against industry-standard alternatives
