15. Data Transfer Scheduling with FTS 3

Alessandro Di Girolamo (CERN), Cedric Serfon (CERN)

15/05/2013, 10:15

- Introduction, status and deployment models - How will Rucio use and interact with FTS 3? - What is the right level for "network-awareness" - the transfer scheduler (FTS) or the DDM layer?

16. Transparency in Networks - End-to-End Performance Data Collection/Aggregation and Problem Diagnositics with perfSONAR

Shawn Mc Kee (University of Michigan (US))

15/05/2013, 10:45

Where are we regarding deployment, functionality, benefit and what is missing?

17. Setting up Federated Data Stores - What is the recommended configuration?

Ilija Vukotic (University of Chicago (US)), Wahid Bhimji (University of Edinburgh (GB)), Wei Yang (SLAC National Accelerator Laboratory (US))

24. Communication needs in agile computing environments

Michael Ernst (Unknown)

15/05/2013, 13:00

We can dynamically acquire 1000's of processors from commercial clouds, but can we also get adequate network connectivity, just in time we need it?

19. Site Configuration and Transfer Performance in the Wide Area Network environment

Hironori Ito (BNL)

15/05/2013, 13:20

Are our transfer engines delivering optimal per-stream performance, what is limiting the performance?

20. Wide Area Network Data Access Requirements in Analysis

Doug Benjamin (Duke University (US))

15/05/2013, 13:45

- Data movement in end-to-end analysis work flows - Implications of the new analysis model proposed by the Analysis Model Study Group - How much data do we replicate through PD2P (for long-term usage) vs. planned replication? What would be the right mix in the future given limited disk space?

23. Summary of LHCONE Point-to-Point Workshop and Discusson on SDN

Artur Jerzy Barczyk (California Institute of Technology (US))

15/05/2013, 14:30

26. Overview of the SINET

Prof. Motonori Nakamura (NII)

15/05/2013, 14:50

21. Specifying the ATLAS Network Needs - an open discussion guided by some fundamental questions

Michael Ernst (Unknown)

15/05/2013, 15:30

- How much networking do we need? Can we deduce the future needs by looking at what we have used in the past? - Is it sufficient to be agnostic/reactive and use what's been offered to ATLAS, or would there be an advantage of being proactive? - Potential of Network-aware Applications in ATLAS - what would be the benefits and what are suitable areas?
