PegasusHub | Build, Run & Contribute

Build & Run

This page provides the necessary tools to take your workflow from a local concept to grid-scale execution. Use modern scaffolding templates to generate your project, choose your execution environment, and finally, share your scientifically verified workflow with the global PegasusHub community.

Step 1: Initialization

Scaffold New Project

Rapidly bootstrap a new Pegasus workflow project using our official generation templates.

Why use Scaffolding?

It eliminates manual setup errors. These tools instantly generate a standardized directory structure, boilerplate Python scripts, and the pegasus.properties file.

Copier vs Cookiecutter

Cookiecutter is the classic one-time generator. Copier is recommended because it supports project lifecycle updates, allowing you to seamlessly pull upstream template improvements into your existing project later.

View Template Repository

Copier Engine Recommended

pip install copier
copier copy https://github.com/swarmourr/pegasus-wms-template.git ./my-project

Cookiecutter Engine Classic

pip install cookiecutter
cookiecutter https://github.com/swarmourr/pegasus-wms-template.git

Step 2: Execution Environments

Choose Your Environment

Select the computing infrastructure that best matches your workflow scale and access requirements.

Managed Cloud

ACCESS Pegasus

Connect directly to national cyberinfrastructure via Open OnDemand and Jupyter. Ideal for research projects needing managed resources without complex setup.

Grid Computing

OSG OSPool

Execute massive high-throughput workloads across global distributed resources on the Open Science Grid. Best for large-scale computations with millions of jobs.
