Outline

• Sergios road map for the transition of DOSAR
• from D0 to LHC
• Growing pains new directions of DOSAR IACS
• Survival Requirements for a Diverse VO
• The Roadmap Revisited

Sergios 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?

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?

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.

DØSAR Strategy

• Maximally exploit existing software and utilities
  to enable as many sites to contribute to the
  experiment
• Setup all IACs 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 individuals 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

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

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.
