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?

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

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 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

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

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.
