RPC Data Certification

M. MaggiINFN Bari

Goals

• RPC system should provide understood Data and Performance to get any CMS result

• Interface the RPC with Physics Validation Team (PVT) flagging each DataSet of Data and MonteCarlo processing

RPC Certification

The DQM RR

The DQM role (Anna Cimmino)

• Used by Central Shifter– Provide a clear set of Histogram coping

with each individual case:• Deal with HV bit• Deal with Statistics• Appropriate use of Noise and Signal

• Used by RPC Shifter– Provide more deeper insight to potential

problem. RPC needs WBM tools for Online Diagnostic

The DQM Framework

• P5 Online System. Code must be performing and synthetic…

• Offline T0 for Stream and Reco. Code must be robust

Not everything can go to DQM system!but can use DQM style

Automatic Certification

• DQM Shifter Based• Learning phase, with have still to get a

coherent picture

The Release Validation Role (JungHwan Goh)

• The RPC Software is Degradable– CMS Framework Changes – Connections to DB– OS and Compiler upgrades– Stricter Coding rules

For Each Release

Set of Standard DQM-like Plots in different areas: Geometry/SimHit/Digis/LocalReco/…. /DQM?

Conclusion

• Certification is a task that needs Diagnostic Tools DQM,WBM

• There is a clear interplay among SW Validation, DQM, and Prompt Analysis

• There is a continuous Data Processing

Open Issues

• WBM needs to be finalized and we need to clarify the use for Certification

• DQM needs consolidation for muon based quantities

• Prompt Analysis requires a redesign…. (DQM/CAF, CRAB based, ….)
