GIOD - Database of “real” LHC events
Would like to evaluate system performance with realistic Event objects
Caltech/HEP submitted a successful proposal to NPACI to generate ~1,000,000 fully-simulated multi-jet QCD events
- Directly study Higgs ? ?? backgrounds for first time
- Computing power of Caltech’s 256-CPU (64 Gbyte shared memory) HP-Exemplar makes this possible in ~few months
Event production on the Exemplar since May ‘98 ~ 1,000,000 events of 1 MByte.
Used by GIOD as copious source of “raw” LHC event data
Events are analysed using Java Analysis Studio and “scanned” using a Java applet
