HFT University — C++ Microbenchmark Challenges

High-performance C++ coding challenges with certified benchmark results.

How It Works

1. Subscribe at hftuniversity.com ($5/month)
2. Create a private repo and copy this template into it:

   git clone https://github.com/Vitorian/hft-challenges.git my-challenges
   cd my-challenges
   git remote set-url origin git@github.com:YOUR_USER/my-challenges.git
   git push -u origin main

3. Set up your repo at hftuniversity.com/challenges/setup
4. Solve challenges by editing files in each challenge's solution/ directory
5. Test locally using CMake + Google Benchmark
6. Submit on the challenge page — our server builds and benchmarks your code on controlled hardware

Building Locally

Requirements: GCC 13+ or Clang 17+, CMake 3.20+, Google Benchmark

cd challenge-01-order-book
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build
./build/benchmark

Rules

• Edit only files inside solution/ directories
• Your code must compile with -std=c++20 -O2
• No inline assembly, no compiler-specific intrinsics (unless stated otherwise)
• Pre-installed libraries (Boost, Abseil, TBB, etc.) are available — see the full list on the website
• Time limit and memory limit are per-challenge (see each challenge's README)

Getting New Challenges

When new challenges are published, pull from upstream:
