Why is physics interested in Grids and who else
benefits

• The LHC starts this year...
• The worlds largest terrestrial scientific
  endeavour ever undertaken
• Thousands of Physicists and Engineers, costing
  billions (of Swiss Francs) to build. Two general
  purpose experiments and two specialised
  experiments. Two of the four leaders from
  Imperial.
• Will produce tens of PB a year of data and need
  similar amounts of Monte Carlo simulated data.
• Particle physicists need large, distributed
  computing and so have become important members of
  the overlapping landscape of Grid projects
  (centred around EGEE)
• EGEE is tasked with providing an e-Science
  infrastructure for many different areas of
  Science not just particle physics, however the
  deadline of the LHC has forced EGEE to produce a
  reliable infrastructure on a short timescale.
• Large role of particle physics (and biomedical
  applications) mean that support for throughput
  jobs is more highly developed than for parallel
  jobs although this is improving.
• Within Imperial College, Grid activities have
  been (largely) a collaboration between LeSC and
  the High Energy Physics Group

EGEE Enabling Grids for E-sciencE
EGEE is the Worlds largest Grid project Over
300 sites at over 240 institutes, 41,000 CPUs,
5PB of online disk, 20PB Tape Storage
Within the UK

• EGEE activity mainly funded through GridPP
• Equipment funded through a variety of sources
• Support and Management structure with one Tier 1
  and 4 regional Tier 2s.

LondonGrid

• LondonGrid (aka London Tier 2) consists of nine
  sites at five institutions Brunel, Imperial
  College, QMUL, RHUL UCL with Imperial as the
  lead partner

Imperials Role

• Leads the LondonGrid activity
• Manager and Technical Coordinator of LondonGrid
• Collaboration/Management Boards of EGEE, GridPP,
  GRIDCC and wLCG
• First EGEE site to also be members of the NGS
• Working with smaller communities within the UK
  to enable them to use Grid resources.
• As well as resource delivery and support
  Imperial also
• - Works on performance analysis of the system and
  individual components.
• Provides support for SGE within EGEE
• Delivers the Real Time Monitor (RTM) and other
  dissemination tools
• Carries out RD into new middleware components
  with new functionality
• Contributes to the development of MPI support
  within EGEE

Conclusions

• Imperial College leads Grid computing activities
  within London.
• Imperial College is an active partner in
  National and International Grid projects
• These Grids will continue to enable an
  increasing number of areas of Scientific
  endeavour.
