WLCG Authorisation from X.509 to Tokens
/ Bockelman, Brian (Unlisted, US) ; Ceccanti, Andrea (INFN, Italy) ; Collier, Ian (Daresbury) ; Cornwall, Linda (Daresbury) ; Dack, Thomas (Daresbury) ; Guenther, Jaroslav (CERN) ; Lassnig, Mario (CERN) ; Litmaath, Maarten (CERN) ; Millar, Paul (DESY) ; Sallé, Mischa (Nikhef, Amsterdam) et al.
The WLCG Authorisation Working Group was formed in July 2017 with the objective to understand and meet the needs of a future-looking Authentication and Authorisation Infrastructure (AAI) for WLCG experiments. Much has changed since the early 2000s when X.509 certificates presented the most suitable choice for authorisation within the grid; progress in token based authorisation and identity federation has provided an interesting alternative with notable advantages in usability and compatibility with external (commercial) partners.

Bootstrapping a new LHC data transfer ecosystem
/ Bockelman, Brian (U. Nebraska, Lincoln) ; Hanushevsky, Andrew (SLAC) ; Keeble, Oliver (CERN) ; Lassnig, Mario (CERN) ; Millar, Paul (DESY) ; Weitzel, Derek (U. Nebraska, Lincoln) ; Yang, Wei (SLAC)
GridFTP transfers and the corresponding Grid Security Infrastructure (GSI)-based authentication and authorization system have been data transfer pillars of the Worldwide LHC Computing Grid (WLCG) for more than a decade. However, in 2017, the end of support for the Globus Toolkit - the reference platform for these technologies - was announced. [...]

Adapting ATLAS@Home to trusted and semi-trusted resources
/ Cameron, David (University of Oslo) ; Garonne, Vincent (University of Oslo) ; Millar, Paul ; Sun, Shaojun (Department of Physics, University of Wisconsin) ; Wu, Wenjing (University of Michigan, Department of Physics)
/ATLAS Collaboration
ATLAS@Home is a volunteer computing project which enables members of the public to contribute computing power to run simulations of the ATLAS experiment at CERN. The computing resources provided to ATLAS@Home increasingly come not only from traditional volunteers, but from data centres or office computers at institutes associated to ATLAS. [...]

Optorsim: A Grid Simulator for Studying Dynamic Data Replication Strategies
/ Bell, William H (Glasgow U.) ; Cameron, David G (Glasgow U.) ; Millar, A Paul (Glasgow U.) ; Capozza, Luigi (Mainz U., Inst. Kernphys.) ; Stockinger, Kurt (CERN) ; Zini, Floriano (ITC-IRST, Trento)
Computational grids process large, computationally intensive problems on small data sets. In contrast, data grids process large computational problems that in turn require evaluating, mining and producing large amounts of data. [...]

The dCache scientific storage cloud
/ MILLAR, Paul (speaker) (Deutsches Elektronen-Synchrotron (DE))
For over a decade, the dCache team has provided software for handling big data for a diverse community of scientists. The team has also amassed a wealth of operational experience from using this software in production.
With this experience, the team have refined dCache with the goal of providing a "scientific cloud": a storage solution that satisfies all requirements of a user community by exposing different facets of dCache with which users interact.
Recent development, as part of this "scientific cloud" vision, has introduced a new facet: a sync-and-share service, often referred to as "dropbox-like storage". [...]

dCache, agile adoption of storage technology
/ Millar, Paul (speaker) (Deutsches Elektronen-Synchrotron (DE))
For over a decade, dCache has been synonymous with large-capacity, fault-tolerant storage using commodity hardware that supports seamless data migration to and from tape. Over that time, it has satisfied the requirements of various demanding scientific user communities to store their data, transfer it between sites and fast, site-local access.
When the dCache project started, the focus was on managing a relatively small disk cache in front of large tape archives. [...]
