  20. Some of the contributions of Uniandes engineers to CMS Computing: Computing workflow management Detector Conditions data distribution Quality assurance and control in CMSSW. Manage tools and procedures to enable developers to contribute to CMSSW. CMS Computing Support C. Avila, UNIANDES

  21. Support for the Frontier system, which distributes detector conditions data throughout the WLCG (Worldwide LHC Computing Grid). Support for the associated WLCG Squid network, deployed to decrease load on central Frontier servers. Implementation of the mandate of the WLCG Squid Monitoring Taskforce, encompassing CMS, ATLAS and the CVMFS system. Tracking, debugging and monitoring of workflows Improving and developing monitoring scripts and tools Detector Conditions Data Distribution C. Avila, UNIANDES

  22. Daily operations of the CMS computing jobs distribution system, GlideinWMS. Deployment and updating of WMAgent software for CMS Workflows management. Daily operations of the CMS Dataset Book-keeping Service (DBS), currently transitioning from v2 to v3. Computing Workflow Management C. Avila, UNIANDES

  23. Quality assurance and control in CMSSW. • Test new changes proposed by the developers for the current releases. • Run code analysis tools to perform efficiency checks and optimization. • Inform developers about errors and problems found in the releases caused by their codes C. Avila, UNIANDES

  29. FINANCIAL SOURCES: HELEN program (ALFA II), EPLANET, COLCIENCIAS, CMS, UNIANDES HELEN 22 Latin American Institutions 17 European Institutions Countries participating: From Europe: France, Germany, Italy, Portugal, Spain, United Kingdom From Latin America: Argentina, Brazil, Chile, Colombia, Cuba, Mexico, Peru, Venezuela. ~70% of fellowships for mobility to CERN HELEN and EPLANET are finished. We need a new international project. This is important for mobility of students, postdoc and professors.

  30. GOALS & PERSPECTIVES FOR 2014 • Continueouractivities in MEDIPIX with new MScstudent in collaborationwiththebio-engineeringdepartment and otherColombianuniversities. • Continueourparticipation in theRPCs • Maintaintheparticipation of ourengineers in the CMS computing M&O A program. • Finishthesis of Juan Pablo Gómez on stop searchwith t-tbarbackgroundreductionwithmatrixelementsmethod. • Advancewiththesis of Luisa Chaparro onHiggsdalitzdecay. • Startthesis of Andres Cabrera on SUSY VBF withmuons in final state Thisthesiswillhelptopavethewayforourcollaborationwith Texas A&M and Vanderbilt. • Startourcontributiontothe GEM project.  Collaborationwith Texas A&M and Vanderbiltseems positive. • Wehavealsointerest in participating in a SUSY phenomenology- experimental project in collaborationwith Texas A&M and Vanderbilt Possiblywith new PhDstudent Felipe Gonzalez. • Needtowritesomeinernal notes forthework done byourgroup, includingservicework and theses of ourstudents. • Needtofind new externalsourcestofinanceouractivities, speciallymobility.
