Open-source software

The software
behind the fabric.

FabAID is built on two open-source platforms, developed in the open for decades and trusted at national scale — the Pelican Platform for data, and the HTCondor Software Suite for computation. Together they let any researcher connect any repository to computing capacity anywhere.

The data platform

Pelican moves data to where science happens.

Pelican federates data repositories into a single namespace and delivers their objects — through a national network of caches — right next to the compute that needs them. It is the software foundation of the Open Science Data Federation. In FabAID, we are evolving Pelican to meet the demands of AI-driven science: tighter ecosystem integration, metadata extraction and discovery, lightweight ways to connect smaller repositories, and improved staging management.

  • Federate any repository — connect storage you own by running an origin service.
  • Deliver data anywhere — caches across the US cyberinfrastructure pull hot objects close to compute, on demand.
  • Evolving for AI-driven science — improving metadata, discovery, and scale for the next generation of data-intensive workloads.

Pelican Platform
HTCondor Software Suite
The workload engine

HTCondor turns raw capacity into effective throughput.

The HTCondor Software Suite manages and executes high-throughput workloads whether on a laptop or hundreds of thousands of cores. In the fabric, HTCondor is the workload engine powering FabAID's Access Points and data workflow services, scheduling the jobs that generate, transform, and move data across the federation.

  • Scale without rewriting — the same workload runs from a laptop to national-scale capacity.
  • Powers the Access Points — managing data-intensive and AI workloads.
  • Drives data workflows — orchestrates the services that ingest, process, and copy datasets across the fabric.

Open by design

Developed in the open, hardened at national scale.

Both platforms are free and open source, built by CHTC at the University of Wisconsin–Madison and used worldwide.
