Submission

To submit your solution, please create a fork of this repository and submit a pull request to the main branch. Your pull request should include the following:

• A new directory in the solutions directory named after your GitHub username.
• This should contain a binary rust project with your solution.
• The binary should accept a single argument, that is the file path to the input file.

For example, if your GitHub username is sassman, your solution should be in solutions/sassman. It should be callable like this:

cd solutions/sassman
cargo run --release -- ../../samples/weather_100.csv

The output should be written to stdout.

Please note that CI will run on your pull request to ensure that your solution compiles and runs correctly.

:NOTE: If you have any questions, feel free to ask in the #hack-evening-2024-4 channel on the Rust Munich Discord server.

Good luck! 🦀

CI is your friend

• Your PR is automatically checked by GitHub Actions
• Benchmarks are exectued and results are provided as Comment on the PR, you can use this as a tool
• Flamegraphs are also produced during the build, they should appear on the PR as comment as well

Submission Evaluation

We are evaluating submissions by benchmarking them on a set of three self-hosted Github runners with dedicated vCPU cores. The servers are AMD EPYC instances (CCX33) from Hetzner with the following specs:

You submission will be terminated after 8 minutes (including build time).
