Hydro
Hydro is an online judge platform and competitive programming management system. It provides the infrastructure to host programming contests, manage a library of programming problems, and evaluate code submissions against predefined test cases and time limits.
The system utilizes a distributed code execution engine that scales judging tasks across multiple worker nodes to process high volumes of submissions. It is built as a modular judge framework, employing a plugin-based architecture that allows for the extension of system functionality without modifying the core source code.
The platform covers administrative capabilities including role-based access control with granular permissions and multi-tenant space isolation to segment users and data. It also includes tools for programming contest management with leaderboard control, problem set imports from external platforms, and configuration-driven language support to define compilation and execution logic.
Features
- Competitive Programming Platforms - Provides a complete platform for hosting programming contests and evaluating code submissions against test cases.
- Distributed Job Execution - Implements a scalable infrastructure that distributes code evaluation tasks across multiple worker nodes.
- Task Distribution Scaling - Distributes judging tasks across multiple independent worker nodes to scale processing capacity.
- Competition Management Systems - Provides a tool for organizing programming competitions with leaderboard management and granular access controls.
- Management Tools - Provides comprehensive tools to organize competitions, including leaderboard freezing and flexible scheduling.
- Online Judges - Provides administrative tools for managing problem libraries, user accounts, and automated grading.
- Modular Frameworks - Provides a plugin-based architecture for extending judge functionality without modifying core code.
- Sandboxed Code Evaluators - Provides a sandboxed environment to compile and execute user submissions and compare results against expected outputs.
- Distributed Evaluation - Scales the judging system across multiple worker nodes to process high volumes of submissions efficiently.
- Modular Plugin Architectures - Implements a modular plugin architecture to extend system capabilities without affecting core updates.
- Plugin-Based Architectures - Employs a plugin-based architecture that allows adding new features without modifying the core source code.
- Execution Configurations - Allows defining supported languages by specifying compilation and execution commands within configuration files.
- Load-Based Fleet Scaling - Automatically adjusts the number of active evaluation workers based on the system queue and real-time load.
- Isolated Learning Spaces - Creates isolated spaces with specific roles for students and teachers to track academic progress.
- Collaborative Space Isolation - Segments users and data into independent environments with dedicated administrative controls and segregated resource access.
- Granular Permission Systems - Provides a role-based authorization system with granular permissions assigned to users or groups for contests and assignments.
- Multi-Tenant Isolation - Provides multi-tenant isolation to segment users and data into independent environments with dedicated controls.
- Role-Based Access Control - Manages system permissions by assigning granular rights to users and groups based on specific roles and contests.
- Language Support Definitions - Implements configuration-driven definitions that allow the system to support various programming languages for compilation and execution.
Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
