Diagnose Clock Skew in a HFT Order Matching System

FreeVerified credential4 weeksExpert

Overview

What this challenge is about.

Receive anonymized PTP grandmaster + slave logs (nanosecond resolution, 30 days, 3 cabinets) plus a synthetic order-flow generator. Identify the drift pattern (likely candidate: leap-smear handling and asymmetric network paths). Implement a Hybrid Logical Clock (HLC) prototype in C++ that wraps the existing matching-engine API and falls back when PTP confidence drops below a threshold. Benchmark ordering correctness and added latency vs the current design. Deliver a 12-page diagnosis report, the HLC prototype, and a benchmark report. No production deployment required.

The Brief

What you'll do, and what you'll demonstrate.

Diagnose nanosecond-scale clock drift causing order-sequencing bugs and prototype a Hybrid Logical Clock fallback with measured correctness and latency tradeoffs.

Earning criteria — what you'll demonstrate

  • Reason about physical vs logical clocks in a low-latency system
  • Diagnose nanosecond-resolution timing bugs from real telemetry
  • Implement Hybrid Logical Clocks against a production-shaped API
  • Benchmark correctness vs added latency under realistic order flow
