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

2. DOSAR Workshop at Sao Paulo Dick Greenwood 17SEP05 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. DOSAR Workshop at Sao Paulo Dick Greenwood 17SEP05 3 Sergio’s “road map for the transition 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 Workshop at Sao Paulo Dick Greenwood 17SEP05 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 Workshop at Sao Paulo Dick Greenwood 17SEP05 5 DOSAR IN ATLAS UT-Arlington University of Oklahoma Langston University

6. DOSAR Workshop at Sao Paulo Dick Greenwood 17SEP05 6 DOSAR in CMS SPRACE Louisiana Tech University Ole Miss Others?

7. DOSAR Workshop at Sao Paulo Dick Greenwood 17SEP05 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. DOSAR Workshop at Sao Paulo Dick Greenwood 17SEP05 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 Workshop at Sao Paulo Dick Greenwood 17SEP05 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. DOSAR Workshop at Sao Paulo Dick Greenwood 17SEP05 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 Workshop at Sao Paulo Dick Greenwood 17SEP05 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.
