REDWOOD Summer Workshop

21 Jul 2025, 09:00 → 25 Jul 2025, 12:00 Europe/Zurich

Workshop Scope and Goals: REDWOOD is a small collaboration of investigators from diverse fields of physical sciences combining their efforts to solve the very difficult challenge of complex workflows on large volumes of data distributed across multiple systems. The collaboration includes the University of Pittsburgh, Carnegie Mellon University, The University of Massachussets (Amherst), Brookhaven National Laboratory, Oak Ridge National Laboratory, and SLAC. Their efforts are set to benefit the ATLAS experiment, the Vera Rubin Observatory, and Fusion experiments at ORNL. Workflow management involves the software infrastructure to manage the processing steps which may include simulation, reconstruction, data analysis, or near real-time acquisition and processing of experimental data. Currently, for example, in ATLAS, over 1 million computational tasks execute concurrently on thousands of compute nodes. The collaboration operates on four tracks: Workflow algorithms, near real-time applications, workflow monitoring, and modeling & simulation of workflow. The geographically dispersed collaboration meets 2-3 times per year to insure sufficient contact between the four subgroups.

Dates: July 21-25 2025. A mini-workshop on distributed computing in ATLAS and CMS experiments with discussion sessions with experts, intended for co-PIs is held at CERN in parallel with a hackathon for junior collaborations at the workshop site in Conthey during the first two days; this is followed by an All-Hands meeting during the final three days, in Conthey. 

Location: Tour Lombarde, Conthey Switzerland

Mini-Workshop: CERN, Geneva Switzerland
