The State of DOSAR DOSAR VI Workshop at Ole Miss April Dick Greenwood Louisiana Tech University

–Community and campus based grid organization –Its primary goal is spreading/enabling grid use DOSAR in Korean is the God of Martial Arts DOSAR evolved from the DØ Remote Analysis effort –Coordinated group efforts in DØ simulation/reconstruction/production What is DOSAR ? Distributed Organization for Scientific & Academic Research 4/17/ Dick Greenwood DOSAR VI at OleMiss

History Ancient times: DØ Remote Computing Era –SAM, DØ data management system, in place: pre-2001 –DØ Remote Analysis Model Proposed: Nov –Proposal for RAC accepted and endorsed by DØ: Aug –UTA awarded MRI for RAC: June 2002 –Formation of DØ Southern Analysis Region (D0SAR 1.0) : Apr D0SAR DØ MC Production begins –Activation of 1 st US (Regional Analysis Center) RAC at UTA: Nov –Formation and activation of DOSAR Grid for MC: Apr /17/ Dick Greenwood DOSAR VI at OleMiss

History –Transition to Distributed Organization for Scientific and Academic Research, DOSAR: Apr (DOSAR 2.0) Active engagements with LHC experiments began –DOSAR VOMS installed at UTA: May 2005 –DOSAR registered as a VO in OSG: July 2005 –ATLAS distributed production and analysis system, Panda, implemented at OU and UTA: Jan –All groups engaged in LHC experiments Modern times: beyond DØ 4/17/ Dick Greenwood DOSAR VI at OleMiss

Who is DOSAR ?  First Generation IAC’s University of Texas at Arlington Louisiana Tech University Langston University University of Oklahoma Tata Institute (India) Second Generation IAC’s –Cinvestav, Mexico  SPRACE - São Paulo Regional Analysis Center, Universidade Estadual Paulista; Brazil  University of Kansas  Kansas State University Third Generation IAC’s –University of Arizona, Tucson –Rice University  Ole Miss, University of Mississippi  Iowa State University  Louisiana State University  Oklahoma State University  … 4/17/ Dick Greenwood DOSAR VI at OleMiss

7 Goals DOSAR seeks to bring together institutions which can/must use GRID technology to solve their computing problems (esp smaller institutions) As its needs increase faster than funding, the scientific community should try to tap into these un(under)-used resources but, there are many barriers to utilizing these resources (technical, financial, manpower, …) DOSAR should, as necessary, serve as a representative/liason for these institutions to the greater GRID community DOSAR should help enable maximal use of available resources at the member institutions (strength in collaboration) (member institutions should serve as nucleation points for regional/statewide GRIDS)

Accomplishments → LTU brought in Super-Mike and additional resources for DØ & ATLAS → UTA plays leadership role in HiPCAT, Texas Grid community; Leading BioTex grid, working with chemists, geologists and medical professionals → LTU Working as a leading institution in LONI, Louisiana Grid community → OU and LU have been working toward creating “The Oklahoma state grid”, working closely with OSCER → OU has successfully developed a Condor pool of pc’s running CoLinux on Windows. UTA is developing a similar system. → SPRACE leads Brazilian national grid effort w/ funds!!! 4/17/ Dick Greenwood DOSAR VI at OleMiss

Some Successes in DOSAR Funding Funds from NSF MRI for UTA – RAC: 2002 –C–Construction of the first U.S. university based RAC EPSCoR + University funds for LTU – IAC: 2003 –I–Increase IAC compute resources Brazilian National Funds for SPRACE: 2003 & 5 –C–Construction of an extensive RAC EPSCoR funds for OSU, OU & LU: 2004 –C–Compute resources for IAC –H–Human resource for further development –R–Renewal submitted LTU at part of LONI wins support from State of LA: 2005 OU, LU and UTA, together with UNM, won a joint ATLAS Tier 2 site: 2005 LTU won a joint MRI funds (PetaShare): /17/ Dick Greenwood DOSAR VI at OleMiss

DOSAR Strategy Maximally exploit existing software and utilities to enable as many sites to contribute to the DØ and LHC experiments –Continue to participate in DØ MC and Reco activities in opportunistic manner –Focus on LHC experiments –Support OSG move into the global grid framework –Engage in and contribute significantly in OSG Engage in realization of computing grid beyond HEP –Work closely with campus and state computing people to bring grid onto campuses Bring DOSAR specific computing jobs to the grid Want to make grid usage more commonplace 4/17/ Dick Greenwood DOSAR VI at OleMiss

Working with OSG We accomplished virtually everything we wanted in DØ –J. Snow (LU) is the leader in MC production Bring fresh expertise to OSG Expertise in monitoring solutions such as Ganglia and MonALISA  UTA working on Panda ATLAS monitoring together with CMS experiment LTU continues to investigate HA applications DOSAR now has seat on OSG Council Possibly engage non-HEP science use of DOSAR? 4/17/ Dick Greenwood DOSAR VI at OleMiss

Developments Since Last Workshop 4/17/ Dick Greenwood DOSAR VI at OleMiss Ole Miss is ready to resume MC production! Got OSG v0.6.0 working (October 2007) Fixed Condor configuration (November 2007) Running OSG Jobs (11/ /2008) Power Failure “broke” Condor (February 2007 Upgraded Condor (April 2007) Reconfigured Farm and Upgraded OSG (April 2007)

Further Developments 4/17/ Dick Greenwood DOSAR VI at OleMiss DOSAR Members Very Active in LHC Preparations for Data Taking All ATLAS members engaged in Tier 2 and Tier 3 FDR activities  Jim Cochran (ISU)leads the US ATLAS FDR effort and was recently appointed Chair of the U.S. ATLAS Analysis Support Activities Sao Paulo Groups (UNESP & UFABC) playing similar Tier 2 role in CMS preparations

Conclusions DOSAR is an example of a successful grid organization –Critically important asset to DØ All groups actively engaged in LHC experiments - (and preparations for data taking!) Using DOSAR resources for DØ and LHC data analyses and production Closely engaged in OSG activities Continue Desktop Cluster deployment, CONDOR pools Provide leadership role in state-wide grid efforts Expanding membership and scope 4/17/ Dick Greenwood DOSAR VI at OleMiss
