1. Project Coordination R. Cavanaugh University of Florida

2. Important UltraLight is a project with two equal and symbiotic activities –Application driven Network R&D –Not just a networking project, nor solely a distributed data analysis project UltraLight is a Physics ITR –Ultimate goal Enable and produce physics (more generally e-science), which could not otherwise be performed –Network Technical Group is the “backbone” of the Project Activity: Perform network R&D Metric: CS Publications, demonstrations –Applications Technical Group is the “driver” of the Project Activity: Perform “middleware” R&D, perform LHC Physics research Metric: CS and Physics Publications, demonstrations, community adoption

3. Relationship between UltraLight and LHC CMS –CCS APROM –US-CMS S&C Tier-1 UAF Tier-2 Program DYSUN Tier-2c ATLAS ATLAS and CMS will integrate the UltraLight Application Services respectively into their own separate Software Stacks

4. LHC Computing Model: Requirements and Scale

10. Project Management Web-page portal –Wiki, etc Mail-lists Regularly scheduled phone and video meetings Periodic face-to-face workshops Persistent VRVS room for collaboration Reports –Technical –Annual

11. Project Structure of UltraLight In the Proposal –HEP Application-layer Services –e-VLBI Application- layer Services –Global Services –Testbed Deployment and Operations –Network Engineering –Education & Outreach Current –Applications CMS ATLAS e-VLBI Global Services Testbed –Network Global Services Testbed Engineering –Education & Outreach

12. Connection between Application and Network Tech. Groups

13. Project Plan Short term Longer term

14. 6-month Overall Project Goals Establish early ties to the LHC –Tightly couple with LHC experiment needs and timelines Possibly take on official roles within experiments? –Must aggressively come up to speed to be meet LHC milestones –Already underway… Establish collaborative ties with external partners –OSG, Grid3, CHEPREO, AMPATH, etc –Already underway… Establish scope of the project –Evaluate trade-offs between R&D interests and application needs Functionality and LHC timeline –Determine what technology we Can adopt off the shelf Must develop to meet project goals Establish initial UltraLight infrastructure and user community

15. Early Focus of the UltraLight Technical Groups Networking –Construct the UltraLight Network Testbed (UNT) Applications –Construct the UltraLight Applications Testbed (UAT) Leverage GAE, Grid3, CMS, ATLAS, etc –Prepare applications that will exploit the Network Testbed E&O –Build relationships with external partners CHEPREO, CIARA, AMPATH, etc To first order, the Network Testbed can be instantiated independently from the Application Testbed and E&O activities –This will be our early strategy –Later, bring the (largely orthogonal) testbeds together in an evolutionary way

16. Longer Term Project Goals (past initial testbed building phase) Global Services –Develop handles which monitor, control, and provision network resources Manually at first, then move to automate –Close collaborative effort between Applications Group and Networking Group Requires the that the UNT and UAT work together as a coherent whole –Combine to operate single UltraLight Testbed (UT) Smooth transformation to UT expected as UNT and UAT activities are very complementary

17. 6-month Network Goals Inventory the different UltraLight sites –What are the current connections available at each site? –What type of switches, how many, and where are they located, etc? Construct the UltraLight Network Testbed –Persistent development environment Piece together all the different network components –Create the NOC Team Begin thinking about disk-to-disk transfers –Interface with Storage Elements –Important for later integration work with Applications

18. 6-month Application Goals Establish UltraLight Application Grid Testbed –Persistent development environment Deploy Application-layer services and middleware Deploy HEP Applications –Create the GOC Team Perform System Integration Tests: Demonstrate –Interoperability of existing UltraLight Application-layer Services –Operability of HEP Applications on top of existing Application-layer Services Study HEP application (ORCA & ATHENA) behaviour in-depth –Execution environment, Data/Metadata Model, Performance Profiles –Current and future versions

19. 6-month E&O Goals Earni and Fabian Network engineers –Networking to brasil $ for E&O connected with CHEPREO Julio and Heidi EO (CHEPREO and UltraLight) QuarkNet –Bring people together to do science –Community aspect

20. 6-month E&O Goals Quark net –Research emphasized –Monte Carlo at FNAL Z0’s with fake detector Teachers see what it is like to be a particle physicists –HS teachers are a different group Need to be long term oriented, substantial, something teachers can sink teeth into

21. 6-month E&O Goals Ideas for what is practical How to fit together Had a grid needs/assesment workshop –There is a writeup Look at live data from CMS Coordinate with applications group –ORCA -> comma separated file -> excel Web browser driven –No special software

22. 6-month E&O Goals Showing students how scientists collaborate –Have meetings between scientists and students (via VRVS?) –Ask a scientist day to highlight networking and HEP –Thinkquest competition Awards Put together ad-hoc grid networks –Workshops and teaching Seamless bridge Ultralight/HEP tools with java applet

23. 6-month User Community Goals Feedback loop between developers and users –Update and confirm the Proposed UltraLight Grid- enabled Analysis Environment –Use actual LHC data analysis work Contribute to the CMS Physics TDR Milestones –Many UltraLight members are strongly engaged Effort recognised in CMS –Application driver for UltraLight! Challenging and essential! Very tight, ambitious schedule to meet however…

24. Demonstrated at SC04 Much Delivered for SC04 CMS P-TDR Analysis Efforts Already Underway (very ambitious schedule) Application Group is already working hard to ramp up in time for the LHC Current UltraLight Application Group Status

25. Current UltraLight Network Group Status Also working hard –Refer to Shawn’s UltraLight Network Technical Document

26. Major Milestones over the Next 6 Months Dec –Initial UltraLight Collaboration Meeting at CIT Jan –UltraLight Week at CIT: UltraLight Applications Testbed Started Feb:CMS PRS Meeting –UM connects to MiLR, UF connects to FLR Mar:CMS Week –FLR declared to be “Production” Apr: May: CMS CPT Week –First round of CMS approvals for analyses to enter P-TDR Jun:CMS Week –UltraLight Meeting (UM?): UltraLight Network Testbed in place
