What’s Next for DOSAR?

1. What’s Next for DOSAR? Dick Greenwood Louisiana Tech University 1st DOSAR Workshop at the Sao Paulo, Brazil September 17, 2005

2. Outline • Sergio’s “road map for the transition of DOSAR from D0 to LHC” • Growing pains: new directions of DOSAR IAC’S • Survival Requirements for a Diverse VO • The Roadmap Revisited

3. Sergio’s “road map for thetransition of DOSAR from D0 to LHC”… * How would we fit in the general structure of LCG? * Will DOSAR VO become a distributed Tier 2 center? * Which would be our associated Tier 1? Fermilab? * What should we do to comply with Atlas and CMS requirements? * How will we share our resources between D0 and LHC?

4. DOSAR in D0: SAMGrid • Reprocessing • Run 2 Reprocessing continues at: • UTA • OSCER • SPRACE • P17 MC Production • UTA • OSCER, OUHEP, LUHEP • SPRACE • LaTech (caps + supermike): soon • Ole Miss: soon

5. DOSAR IN ATLAS • UT-Arlington • University of Oklahoma • Langston University

6. DOSAR in CMS • SPRACE • Louisiana Tech University • Ole Miss • Others?

7. Concerns • Inter-experimental nature of “new” DOSAR • Cohesiveness of group is weakened • Must strive to maintain high level of communications • Biweekly meetings and semi-annual workshops • Continue to help each other with technical help • Continue to create and work on near-term goals.

8. DØSAR Strategy • Maximally exploit existing software and utilities to enable as many sites to contribute to the experiment • Setup all IAC’s with DØ Software and data analysis environment • Install Condor (or PBS) batch control system on desktop farms or dedicated clusters • Install McFarm MC Local Production Control Software • Produce MC events on IAC machines • Enable various monitoring software • Convert to generic SG-runjob based operation • Helped several other DØ farms to be activated (Korea and China) • Participate in reprocessing by sites with large resources • Integrate educational effort • Install SAMGrid and interface it with McFarm • Submit jobs through SAMGrid and monitor them • Perform analysis at individual’s desk • In our transition to a “DOSAR strategy”: • Become a VO within the larger, global effort, OSG • Adapt to LHC style grid-based analysis system

9. DOSAR Participation in the OSG • DOSAR has great potential as international Grid VO due to reputation as an effective grass roots organization and its future access to the National Lambda Rail • Became member VO at OSG Consortium meeting (UW-Milwaukee, July 20, 2005) • Submitted pre-proposal for support of future grid proposals

10. ANALYSES at IACs • Progress in the development of remote analyses has been slower than hoped for- • Optimistic about our analysis efforts in the future: • Effort to integrate DOSAR to LHC experiments should pick up the speed • Would like to see a demonstration of DIAL as described by David Adams yesterday • Hyunwoo has joined ATLAS effort in developing analysis software and will work on applications of DIAL. Joe Steele will support Hyunwoo in this effort. • Encouraged and impressed by demonstration of GAE (CMS) by Michael Thomas

11. DOSAR Should Leverage its Access to the National Lambda Rail • With the development of LONI in Louisana, the Lone Star Network (LEARN) in Texas and similar 10GB/sec networks in Oklahoma, DOSAR will be internationally competitive in Grid computing.
