XrootD Workshop plan

Alastair Dewhurst

The workshop agenda and registration page can be found at:

https://indico.cern.ch/event/1386888/

We would kindly ask you to consider contributing to the workshop in the following areas:

•  Status, statistics and projected usage of FTS and XRootD for Run3 and beyond.

• Storage access for analysis use, including performance and CPU efficiency with emphasis on realistic running conditions (e.g., local disk, EOS, Tier2, remote data access, with or without XCache).

• Data distribution management, needs and use-cases within scientific communities: data management needs of their community, frameworks used and how they integrate FTS and/or XRootD within their workflow.

• Structured input and future requirements from the experiments and community members on the FTS medium-to-long term evolution.

• R&D projects in the realm of data management, data access and data distribution within the Grid world are also invited. This could touch on integrating Cloud Storage within scientific data management workflows or Network projects aimed at optimizing data movements.

• Discussion on connected topics such as Authentication frameworks (IAM, CILogon, etc) and the role of FTS and XRootd for emerging communities (e.g.: SKAO) in the world of scientific data management .

We encourage you to submit the title of your talk, along with how much time you would like to have to present it, using the form at https://indico.cern.ch/event/1386888/abstracts/ . 

Should the title not be sufficiently explanatory, please include a sentence or two of context.
