Hydro
1.0.0
Hydro is an efficient informatics online assessment system. Easy to install, cross-platform, multi-functional, scalable, and has a question bank.
For teachers who are unfamiliar with Linux or too lazy to operate and maintain, we also provide a free, ready-to-use online version.
For details, go to https://hydro.ac to view the operation instructions.
Paste the installation command into the console for one-click installation. After installation, the first user registered will automatically gain super administrator privileges.
Compatible with mainstream Linux distributions, Debian 12 is recommended, and supports arm64 devices (Raspberry Pi, etc.)
LANG=zh . <(curl https://hydro.ac/setup.sh)
Chinese document/English
If the relevant documentation is not detailed enough, please submit a Pull Request or contact the development team for clarification.
Please submit bug and feature suggestions in Issues.
Hydro has designed a modular plug-in system that can easily expand system functionality.
Using the plug-in system, you can still ensure the system's upgradeability after modifying functions.
All historical versions of Hydro can be smoothly upgraded to the latest version.
For plug-in usage and development guidelines, please go to the documentation plug-ins and development chapter.
Hydro supports all mainstream Linux distributions, is compatible with x86_64 and arm64 architecture devices, and can be installed with one click.
Hydro can run normally on Raspberry Pi or Apple M1/M2.
Use hydrooj backup to back up all system data, and use hydrooj restore 文件名to import backup data. The entire process requires no manual intervention.
Hydro provides single-system multi-space support, making it easy to create independent spaces for different classes/grades/schools, etc.
Data other than users in different spaces are isolated by default, and independent administrators can be assigned without interfering with each other.
Questions can be copied across domains and only occupy one space in the system.
Hydro's permissions can be assigned to corresponding users based on competitions/jobs, or users can be grouped (classes) and permissions can be assigned by group. For permission nodes, you can view the screenshot below the introduction.
The Hydro system itself is stateless, which means you can add or delete service nodes at will without affecting the normal operation of the system. The evaluation queue will be automatically distributed evenly among all evaluation machines currently online. After joining the elastic scaling group, evaluation machines can be automatically added or deleted according to the server load. Unlike other systems, Hydro will manage the test data cache between different servers and pull it on demand, so that the evaluation machine can be used immediately after it goes online without manual data synchronization.
Hydro supports all question types. Whether it is traditional question types, Special Judge, file input and output, answer submission questions, IO interaction, function interaction, or even fill-in-the-blank questions, Hydro has corresponding support. After installing the relevant operating environment, Hydro can even do:
Call the little turtle to draw a picture and compare it with the standard picture;
Call the GPU to evaluate the machine learning model;
More samples can be viewed and downloaded in the sample area.
Hydro supports importing question bank files in common formats, including Hydro's common zip format, FPS (xml) format questions exported by HUSTOJ, and compressed packages exported by QDUOJ.
You can download the free question bank from Hydro Question Bank.
Hydro also supports VJudge, which means you can directly import questions from other platforms into the system, modify the questions and incorporate them into your own assignments or competitions to quickly build your own question bank system.
Currently supported platforms are:
Yiyi Tong Programming Enlightenment: The official Yiyi Tong Programming Enlightenment Question Bank is free to use. Please refer to the import instructions in the compressed package.
Simple Programming Contest: The official provides the supporting question bank of Luogu's "Programming Contest (Basics)" for free. Please refer to the import instructions in the compressed package.
UOJ: Well-known OJ in China, commonly used by national training teams;
Codeforces: A large foreign competition platform with a large number of high-quality questions;
Luogu: To use this function, you need to purchase a license from Luogu;
HDUOJ: Hangzhou Dianzi University online evaluation system, which includes multi-school training questions;
CSGOJ: Guangdong Provincial Competition and Hunan Provincial Competition question evaluation platform;
SPOJ: Domestic connections are very unstable and not recommended;
POJ: relatively antique, poor server stability;
YACS: Shanghai Computer Society competition platform, there is a limit on daily submissions for a single account;
HUSTOJ: Theoretically supports all HUSTOJ-driven systems, but due to differences in UI in each system, manual adaptation is usually required.
Hydro supports a variety of competition formats, including ACM/ICPC competition format (supports sealing), OI competition format, IOI competition format, Ledo competition format, and homework functions.
Under the IOI and OI competition formats, the question correction function is supported. Students can submit corresponding questions in the question bank after the game, and their scores will be displayed next to the list.
Under the IOI and OI competition formats, the flexible time function is supported, and students can participate in X hours of their own choice within the set time range.
Hydro's language settings are not hard-coded into the system, but rather using configuration files. As long as it can write compilation commands and run commands in the corresponding language, Hydro can judge questions.
