Title: IHG Innsbrucker Hochenergiephysikgruppe

1
IHG (Innsbrucker Hochenergiephysikgruppe)

The High Energy Particle Physics group (IHG) at
the Institute for Experimental Physics Innsbruck
is involved since its beginning of the activity
in 1968 in the data analysis for significant HEP
Experiments at CERN. For the time being, IHG is
member of ALEPH and ATLAS Collaborations.
The research fields of IHG includes
Test and Phenomenology of the Theory of Strong
Interactions (Quantum Chromodynamics, QCD)
Searches for Higgs Bosons
B-Physics
Software Development and Validation for HEP
Experiments
Participation to the development and deployment
of the world-wide GRIDstructure for the analyses
of HEP data.

ATLAS Detector (http//atlasexperiment.org)
Collaboration 1800 physicists from more than 150
universities and laboratories in 34 countries.
1 Petabyte / year, analysation needs approx.
50.000 CPUs
Start 2007

2
LHC-Computing Grid (LCG)

LCG-Cluster HEPHY-UIBK 6 CPUs (soon 24), 1.7 TB
disk storage
participates in ATLAS Data Challenge 2 (Start end
of june)
ATLAS DC2 uses LCG, Nordugrid, Grid2003, e.g.
100000 detector simulation jobs, each up to 30
hours (SI2k1000)

ZID-Grid Innsbruck

Collaboration HEPHY and ZID Innsbruck
Using students PC-labs over night, weekends,
during holidays
Up to 299 PCs
145 P 4, 1.8 GHz, 512 MB RAM
88 P 4, 2GHz, 256 MB RAM
66 P 3, 1GHz, 256 MB RAM
can be grouped into clusters as needed (e.g.
several clusters as development testbed and one
or more production cluster) with OpenPBS, Torque,
SGE, or Condor as local resource management
MDS Glue Schema, information collected at
agrid.uibk.ac.at
Prototype of Web interface (upload files and
proxy-certificate using grid certificate, define
several parameter studies in one text file)

Example CPU-Load (seen by Ganglia Monitor) for a
Detector simulation using two clusters over a
weekend, 141 jobs total, 43 GB Output
(transferred with gridftp) Runtime 80 compared
to HEPHY LCG-Cluster
