Same feed.
Network ingest.
Week 5 is the capstone network gateway: receive the fixed wire-format tick stream over UDP, run the Week-1 z-score strategy, pass the order-stream determinism gate, then compete on wall-clock run time and throughput on the same held-out feed, on the same machine.
wall-clock replay of the held-out tick feed
ticks processed per second on the judge machine
Five steps from sign-in to leaderboard.
- 01
Read the project brief
Week 5 ships the same binary tick feed as Week 4 and the same canonical order stream. Your gateway must match the reference order-for-order first.
- 02
Implement create_gateway
One translation unit:
gateway.cpp. Threads are allowed — ingest over UDP, hand ticks to the strategy, and merge to one ordered order stream. - 03
Submit gateway.cpp
Drop your single
gateway.cppon the dashboard. The judge compiles it with threads enabled and queues evaluation automatically. - 04
Correctness, determinism, then time
The judge diffs your order stream against the answer key, then runs the same feed K times. A race means no rank — fix it before you tune.
- 05
The leaderboard updates
Score ranks wall-clock run time and throughput once reference denominators are captured on the judge machine.
Share your public repo
Week 5 · network gateway. Public repo link submissions are open until 23:59 IST on Sunday 12 July. You can update your URL until then. A place on the gateway leaderboard required a correct, deterministic gateway.cpp evaluated while rankings were open.

Submit a public GitHub or GitLab URL with your Week 5 network gateway project for cohort review. This is separate from uploading gateway.cpp on the dashboard.
Before you submit
- Public repo on GitHub or GitLab — private repos cannot be reviewed.
- Your

READMEwith build steps, thread count, ingest notes, and headline throughput numbers. - Include
