Eighth Rucio Community Workshop

3 Nov 2025, 11:00 → 7 Nov 2025, 14:00 Europe/London

Square Kilometre Array Observatory Global Headquarter

Rucio is a software framework that provides functionality to organize, manage, and access large volumes of scientific data using customisable policies. The data can be spread across globally distributed locations and across heterogeneous data centers, uniting different storage and network technologies as a single federated entity. Rucio offers advanced features such as distributed data recovery or adaptive replication, and is highly scalable, modular, and extensible. Rucio has been originally developed to meet the requirements of the high-energy physics experiment ATLAS, and is continuously extended to support LHC experiments and other diverse scientific communities.

For this 8th edition of our workshop we will meet at the Square Kilometre Array Observatory Global Headquarters, Jodrell Bank, UK (Nov 3 - Nov 7).

We have a mailing list and mattermost channel, to which you can subscribe, where we will send more details about the program.

We also support the possibility to participate to the workshop remotely via Zoom. Please register to receive the connection details.

Speaker: Luca SCOTTO LAVINA

09:40 Rucio in the DUNE collaboration: tokens and uploads

The DUNE collaboration has been making heavy use of Rucio for several years. The past few months have brought two particular challenges, namely transitioning from x509 certificates to token based authentication using CILogon tokens, and dealing with scalability problems connected with uploading files to Rucio. As DUNE is the first large experiment to attempt to use a token provider other than IAM with Rucio, as well as the only large experiment to make intensive use of the Rucio upload client, these have presented some unique issues. In both cases DUNE has been working closely with the core Rucio development team to identify solutions and make any necessary changes to the code. In the course of this we hope to improve Rucio's support for OIDC token providers, as well as optimising the upload client.

Speaker: James Perry

10:00 Rucio for KM3NeT [Remote]

The KM3NeT collaboration is building a neutrino telescope in the Mediterranean sea, to study both the intrinsic properties of neutrinos and cosmic high energy neutrino sources. Once fully constructed, our computing needs will rise to an eventual data volume of ~500TB of new data per year, and computing needs of ~2000 cores on average. This will require a transition towards distributed computing and data storage.

This talk will cover our plans for the infrastructure and software required for our distributed storage solution, based on RUCIO, the current status and testing of our implementation with ~20% of the detector constructed, and what is still left to do.

Speaker: Dr Francisco Vazquez de Sola Fernandez (Nikhef)

12:20 The interTwin Digital Twin Engine Data Lake

The interTwin project, funded by Horizon Europe, developed a Digital Twin Engine (DTE) to support interdisciplinary Digital Twins (DTs). It brought together infrastructure providers, technology experts, and scientists from fields such as High Energy Physics, Astrophysics, Radio Astronomy, Climate Research, and Environmental Monitoring.

Our presentation focuses on the design and implementation of the interTwin Data Lake, highlighting key extensions and integrations that support diverse resource providers — from HTC and HPC to cloud environments — while meeting the needs of various user communities. The Data Lake is built around the Rucio data management software deployed at DESY, complemented by FTS as a file transfer service and multiple integrated storage technologies across sites such as EuroHPC VEGA, EODC, DESY, INFN, PSNC, CESGA, and KBFI, with ongoing integrations that include the University of Vilnius and DZA. It leverages EGI Check-in as the identity provider.

To facilitate site integration, we developed Teapot (https://intertwin-eu.github.io/teapot/), a multi-tenant WebDAV application built on StoRM-WebDAV. It includes a manager that handles user authentication, external-to-local identity mapping, and request forwarding to a dedicated StoRM-WebDAV server. It also integrates with ALISE (https://github.com/m-team-kit/alise), which implements site-local account linking, enabling users to associate their local accounts with multiple external identities.

Additionally, we will present integration details from selected DTs and upper architecture layers. For example, we support triggering workflows when new data become available in the Data Lake, integrate community-specific data catalogs, and more.

Speaker: Dijana Vrbanec

12:40 Rucio data management system for the SPD experiment [Remote]

The Spin Physics Detector (SPD) is a new experiment under construction at the second interaction point of the NICA collider, JINR. Its primary goal is to test fundamental aspects of Quantum Chromodynamics (QCD) by studying the spin structure of the nucleon. This will be achieved through collisions of longitudinally and transversely polarized protons and deuterons, reaching a center-of-mass energy of 27 GeV and a luminosity of up to 10³² cm⁻²s⁻¹. At peak performance, the detector is expected to generate data at a rate of 0.2 Tbit/s.

To manage this substantial data volume, the SPD will rely on a distributed computing environment. The Rucio Data Management system was selected to orchestrate this complex task effectively.

This report details the experience of deploying Rucio for the SPD experiment. It will cover integration with ancillary services, the development of custom utilities, the automation of workflows, and the implementation of comprehensive monitoring systems.

11:00 The Italian scientific datalake: case studies and insights

The INFN (the Italian National Institute for Nuclear Physics) operates, since more than two decades, one of the italian largest distributed computing infrastructure, providing computing and storage resources for more than 100 scientific collaborations. A sizable fraction of the computing capacity integrates with the WLCG (Worldwide LHC Computing Grid) infrastructure, while others are currently accessible through multiple interfaces such as interactive, batch/grid and cloud.
Since 2022, the Italian National Recovery and Resilience Plan funded a comprehensive infrastructure modernization through the “Italian National Center on HPC, Big Data and Quantum computing” and “Terabit”. The aim is to address the upcoming computational challenges, among them the integration of the Grid, cloud infrastructures, and, notably, CINECA HPC center with its pre-exascale system “Leonardo”.

As a follow-up of the previous workshop, we will showcase how we are leveraging RUCIO to create a datalake stack that can serve multiple communities with their own needs, providing seamless access to data over several distributed centers. We will present an update on how the deployment and operation phase is evolving (e.g. dynamic storage areas for HPC data staging) and what are success stories as well as the shortcomings emerged during these activities. We discuss how we tailored authorization models around our use cases, an evaluation of monitoring and UI solutions, and results of the first experimentations with external metadata catalogs. Furthermore, we are planning the evaluation of a “Rucio-as-a-Service” platform, aiming for streamlining the adoption within smaller communities.
Finally, we’ll present the main results of a preliminary security assessment based on the OWASP framework, with the aim to start a discussion about the feasibility of exploiting RUCIO/FTS for sensitive data management (e.g. for life science research).
The overall purpose is to provide insights valuable for similar large-scale and heterogeneous scientific data management initiatives, through the sharing of our experience.

Building on the achievements of ESCAPE, Rucio is well-positioned to lead the development of European-scale data lakes, providing the scalability, and interoperability needed to support scientific research. This contribution is not a program of work, it aims to share the experience and the challenges that CERN is gathering while participating in the build-up phase of the EOSC Federation, as well as engaging with domains beyond HEP.

Speaker: Giovanni Guerrieri (CERN)

11:40 MADDEN Project: Multi-RI Rucio with POSIX-like Interfaces for Collaborative Data Access [Remote]

Large-scale experiments, such as those in gravitational-wave (GW) science, generate massive datasets stored in isolated Data Lakes, which hinders collaboration and efficient data analysis. The MADDEN (Multi-RI [Research Infrastructure] Access and Discovery of Data for Experiment Networking) project aims to overcome this by extending Rucio to enable read-only access to data for users of other experiments, without the overhead of user management.
As part of this effort, we have implemented prototype Data Lakes for the Einstein Telescope and the Cosmic Explorer. A prototype Multi-RI Rucio client has been developed, enabling access to the Mock Cosmic Explorer server without the need for dedicated user accounts. Furthermore, initial work has begun on a POSIX-like view application built on Rucio. In particular, RucioFS—an existing POSIX-like prototype—was tested to evaluate its capabilities under conditions involving a large number of files and its performance when scaling to increasing numbers of concurrent users.
These developments represent key steps toward the realization of interoperable, user-friendly data management solutions that will support international collaborations in GW science and beyond.

The physics information contained in the strain time series will increase, while on the machine side the size of the raw data from the interferometers will scale with the number and the complexity of the detectors. To meet ET specific computing needs, an adequate choice of the technologies, the tools and the framework to handle the collected data, share them among the interested users and enable their offline analysis is mandatory. The solution currently under test for the data management and distribution is based on Rucio and on the concept of Data Lake. This talk will provide an overview of the requirements and desiderata for the GW community: data type, metadata of interest, modalities for data access and data discovery. Moreover, the test setup deployed so far will be described.
