  1. Examine Overview D0 Online Workshop June 3, 1999 Jae Yu Outline 1. What is an Examine? 2. How Many Examines? 3. How does it work? 4. What are the features? 5. What do we need more? 6. Conclusions

  2. D0 Online Workshop, June 3, 1999, J. Yu What is an Examine? An Online Event Analysis Program that provides sufficient information to monitor Detector performances and/or Data Integrity. What are its jobs? 1. Accept Requests by Triggers or Streams (By names or bit numbers) 2. Perform Analyses and Provide info. (Unpack, Reconstruct, and Fill histograms and Ntuples) 3. Provide Sufficient Tools for Monitoring (Histogram comparison, etc) 4. Store Information into archives (Histogram files, hard copy printouts, etc) 5. Must Incorporate Event Display

  3. D0 Online Workshop, June 3, 1999, J. Yu How Many Examines? Detector Examine 1. Tracking Systems: SVX( ) CFT (Andre Mayorov, N. Graf ) 2. Pre-shower Systems: CPS( ) FPS( ) 3. Calorimeter Systems: CC+EC( ) ICD ( ) 4. Beam Systems: L0 ( ) FPD( ) 5. Muon Systems: Central ( ) Forward( ) 6. Which detector did I miss???? Trigger Examine ( ) Global Examine ( ) Captain’s Examine ( ) Anything-else-you-can-think-of-Examine

  10. D0 Online Workshop, June 3, 1999, J. Yu So What is There? 1. Data Distributor & Collector/Router 2.Interactive Framework (D0 Note #3750) 3.Network Event Transfer (ReadEventDaq) 4.Two Detector Examine Packages (Calorimeter and CFT) 5. Rudimentary ROOT GUI Features? 1. RCP Controlled Event Selection (ReadEvnetDaq) 2. RCP Controlled Output Histogram Archive 3. Multi-Threaded Event Buffering in DD and ReadEventDaq (Depth RCP Controllable) 4. File Event Transfer 5. Histogram on Shared Memory (HBOOK) -ROOT format to follow soon. 6. First Batch of ROOT Histograms Implemented 7. And many more…..

  11. DD Host & Port DD Event Buffer Depth ReadEventDaq Event Buffer Depth

  12. D0 Online Workshop, June 3, 1999, J. Yu What More Do We Need? 1. Complete Interactive Framework (JBK) 2. Finalize Process Control GUI 3. Finalize Event Selection Scheme 4. ROOT Histograms in Shared Memory 5. Finalize Histogram Control GUI 6. Incorporate Sub-detector Examines (Need to identify representatives) 7. Incorporate Event Display 8. Re-verify L3 C/R DD Examine Network Event Transfer (NET) 9. Improve Existing ones 10. Global Examine, Captain’s Examine… 11. What did I forget?

  13. D0 Online Workshop, June 3, 1999, J. Yu Highest Priority: Detector Commissioning We have A working version of Examine Framework and two Example Packages But Not Enough!!!! Need Commitments from Detector Groups You are more than Welcome to take the Responsibility!!!!! Let’s Fill Up the List!!!!!! Good for your Preparation for Run II Offline Analyses
