Questions

• Why having an Analysis Facility at US-ATLAS?

Objectives

• Understanding: US-ATLAS Shared Tier-3 Analysis Facility at UChicago

• Provide contact information and documentation sources

US ATLAS has three shared Tier 3 analysis facilities providing software & computing resources, one of the most recent is located at The University of Chicago and was pre-launched in October 2021.

• Large login nodes for develpment & batch pools or larger-scale processing
• Storage for local datasets & XCache for remote datasets
• Access to ATLAS & analysis software and tools

Broad range of activities carried out & supported at the facilities, including:

• Event generation, detector simulation with ATLAS or standalone software
• Data movement (via R2D2) and access (using Xcache)
• Data processing for analysis & statistics using ATLAS software in CVMFS
• Graphical applications for example via X-windows
• Software development, testing code before submitting to batch system or Panda
• Supported for Run 3 but also allow for R&D for the future

Software & Computing Resources

• Resources that fill gaps between grid jobs and interactive analysis on local computers
• ssh access and HTCondor batch
• Simple Jupyter notebook scheduling to CPU and GPU
• Coffea-Casa, ServiceX (IRIS-HEP tools for columnar analysis)
• Interactive access: interactive nodes, containers, node flavors
• Processing interfaces: HTCondor access, shared endpoint.
• ~1000 cores co-located and close integration with MWT2. ~1 petabyte of storage
• Users start with: 5TB $DATA, 100GB $HOME, 1500 shared CPU cores, shared GPUs.
