GlueX Collaboration Meeting, October 4-6, Recent results obtained using OSG from Ph.D thesis of Igor Senderovich, August 31, 2012

GlueX Collaboration Meeting, October 4-6, Questions from Council members Do you have a plan There is a long way from 5M h/yr to 50M h/yr. Do you have a plan for how you are going to get there? contribute resources to OSG for Gluex simulations Doing a substantial fraction of these 50M h/yr on the OSG would be feasible, given your track record, but there is a resources gap. Is there willingness from other institutions in Gluex to contribute resources to OSG for Gluex simulations? What can we do to help What can we do to help the NP community realize the potential of the OSG for data-intensive science?

GlueX Collaboration Meeting, October 4-6, Plan for grid simulation challenge  save only true tags  keep 1% hdgeant output (HDDM)  keep 1% mcsmear output (HDDM)  keep 100% dana output (REST) 2000 events/s 80 kB/event 120 kB/event 2.2 kB/event 4.2 kB/event Disk space available: 40 TB  events 60 days of beam ~ 1 year of running at 10 7 tags/s total processing budget to do this (once): 3M cpu-hours

GlueX Collaboration Meeting, October 4-6, OSG Usage by Gluex VO Gluex VO Gluex VO created 9/2009 construction phase until 2014 Experiment is in construction phase until 2014 Usage increasing with demand for Monte Carlo Growth has slowed as work increases to digest the results Task: Task: simulation of background QCD photoproduction (Pythia) Purpose Purpose: develop cuts to suppress background, measure leakage from minimum-bias events into signal sample after cuts, requires very large statistics MC samples, shared between analysis tasks. Plans: saturate at the level 5-10M cpu.hr/yr until physics data collection begins ca Strategy: glideinWMS – support from OSG admins outstanding ! run periodusage 9/2009 – 9/ khr 9/2010 – 9/ Mhr 9/2011 – present2.1 Mhr
