Stimulating gridoriented applications: High energy physics

Stimulating grid-oriented applications High
energy physics

• Progress for Q1 and Q2
• A total of 7,500,000 events were simulated,
  reconstructed and analysed for Higgs decay
  studies a significant fraction of this work made
  use of our TeraGrid allocation. We used the TG
  clusters at Caltech and NCSA, a total of 120,000
  SUs
• 40,000 Graviton background study events generated
  on TG (10 CPU hours per event)
• PYTHIA (event generator) and CMSIM (Monte Carlo)
  codes were successfully ported to IA64.
• 2,000,000 events generated on TG for Higgs QCD
  background study
• Work on Grid Analysis continued with the goal of
  providing HEP client access to TeraGrid generated
  events
• Demonstrated analysis of remote datasets at
  SuperComputing 2003
• Tested FAST kernels on IA64

• We are frustrated by the fragility of the TG. It
  seems to be properly operational only 50-60 of
  the time. Limits ability to use allocation.
  Causes long queues. Security shutdowns have
  severely affected our plans recently. The
  following milestones reflect this uncertainty.
• Q3
• Use new and old generators to produce events for
  Higgs and radion searches at a realistic 100,000
  to 150,000 SUs per month on the TeraGrid
• Deploy Clarens (clarens.sourceforge.net) as a
  Grid-based physics analysis Portal on the Caltech
  TG
• Deploy FAST at other TG sites, in collaboration
  with TG network WG, and make tests
• Q4
• Continue event generation to saturate
  allocated/available TeraGrid capacity.
• Deploy Clarens portals at all TG sites
• Work towards ubiquitous deployment on FAST on TG
