GIOD - Summary
LHC Computing models specify:
- Massive quantities of raw, reconstructed and analysis data in ODBMS
- Distributed data analysis at CERN, Regional Centers and Institutes
- Location transparency for the end user
-
GIOD is investigating:
- Usability, scalability, portability of prototype OO LHC codes
- In a hierarchy of large-servers, and medium/small client machines
- With fast LAN and WAN connections
- Using realistic LHC raw and reconstructed event data
-
Results are encouraging … next steps are:
- To expand the CMSOO tests to the WAN and pseudo-production mode
- To test integration of the HPSS with the CMSOO database
- To use measurements of distributed reconstruction/analysis/scanning in LHC computing model simulations
