The Cooperative Computing Lab

We design software that enables our collaborators to easily harness large scale distributed systems such as clusters, clouds, and grids. We perform fundamental computer science research that enables new discoveries through computing in fields such as physics, chemistry, bioinformatics, biometrics, and data mining.

All of our software is open source and available on GitHub. We are always eager to welcome new collaborators—whether you want to explore our software, contribute to development, or receive support. Explore our tools to see how they can power your distributed computing needs, and visit the getting help section if you need assistance.

CCL Launches Redesigned Website (Jan 06, 2026)

Open Source Software

TaskVine is our third-generation workflow system for building scalable data intensive applications that run on HPC clusters, cloud services, and other clusters.

Floability is an NSF funded research project to enable the rapid and portable deployment of notebooks expressing complex scientific workflows across a wide range of cyberinfrastructure.

Work Queue is an application framework for creating and managing dynamic manager-worker style programs that scale up to tens of thousands of machines on clusters, clouds, and grids.

Research Projects

XGFabric : Coupling Sensor Networks and HPC Facilities with Advanced Wireless Networks for Near Real-Time Simulation of Digital Agriculture (DOE ASCR)

This project will explore the design of systems for connecting remote wireless sensor networks with high performance computing systems.

SADE: A Safety-Aware Ecosystem of Reputable sUAS

The overall goal of the project is to develop technology for safety zones that permit only trusted drones to operate in congested or sensitive airspace.

Pledge: Accelerating Data Intensive Scientific Workflows with Consistency Contracts

Expresses workflow I/O intentions using consistency contracts to enable efficient, cluster-wide storage and execution optimizations.

NBFlow: From Notebook to Workflow and Back Again (CSSI Framework)

NBFlow brings together interactive notebook technologies (Jupyter), reproducibility tools (SciUnit), and distributed workflows (TaskVine) to enable easy execution of large-scale notebook workflows on heterogeneous HPC clusters.

TaskVine: A User Level Framework for Data Intensive Scientific Applications (CSSI Element)

TaskVine is open source software for building large scale data intensive dynamic workflows that run on HPC clusters, GPU clusters, and commercial clouds.
