Overview

Covalent is a Pythonic workflow tool used to execute HPC and quantum tasks in heterogenous environments. Users functionalize existing code, apply Python decorators, and then dispatch workflows to the Covalent server. Users can monitor job statuses and view metadata in the Covalent user interface, or query information programmatically via REST API endpoints. Covalent is designed for rapid prototyping and pre-production R&D workflows, so that users can quickly identify optimal software parameters and hardware backends for any particular application.
