A U.S. ATLAS Tier 2 center since 2005, run as one facility across three universities, delivering simulation, reconstruction and analysis for the ATLAS experiment at CERN.

• 42,000 job slots About 646,000 HEPSpec of compute, scheduled with HTCondor
• 26 PB Active disk storage served by dCache at Chicago and Indiana
• 99.8% reliability September 2025 to September 2026, from WLCG published records

In production since 2021, the Analysis Facility gives ATLAS physicists login nodes, notebooks, batch computing, GPUs and petabytes of storage, built on Kubernetes and designed around how people actually work.

• 8,600 cores Local batch capacity, with 13,000 more reachable by flocking to MWT2
• 5.2 PB Ceph-backed user storage, about 1.7 PB usable at three-way replication
• 38 GPUs Across seven nodes, partitioned into 74 allocatable devices

Three Kubernetes clusters in the Hinds building, where new analysis patterns are proven, where Physical Sciences Division and neutrino physicists compute, and where the identity, registry and data management services other facilities depend on actually run.

• River The IRIS-HEP Scalable Systems Laboratory testbed, about 70 nodes
• Pile PSD and SBND analysis cluster, with batch, notebooks and Ceph storage
• Tempest The services cluster carrying identity, registry, OSG and data management

A mirror of ATLAS Open Data in the US, with notebooks and reproducible workflows attached, so that students, educators and researchers can work with real LHC data without an experiment account.

• 1 PB Dedicated dCache storage, separate from the production grid pools
• Runs on RP1 The Lab's multi-site research platform at Chicago and Indiana
• Notebooks and workflows BinderHub and JupyterHub sessions, plus reproducible REANA workflows
