- Report on Successful Data Challenges
- DC1 - December 2012/ January 2013
- 5 billion Events - OSG, JLab, CMU
- 1200 Concurrent Jobs at JLab.
- DC2 - March/April 2014
- 10 billion events with EM backgrounds included - OSG, JLab, MIT, CMU, FSU
- 4500 Concurrent Jobs at JLab
- Well under 0.1% failure rate
- DC3 - January/February 2015
- Read data in raw-event format from tape and produce to DST (REST) files.
- Load up as many JLab cores as possible.
- Run Multi-threaded jobs
- Already doing full reprocessing of the Fall 2014 data from tape every two weeks.
- DC1 - December 2012/ January 2013
- Data Acquisition Successes - Running Fall 2014 (stealth data challenge).
- Exceeded the 300MB/s transfer to tape bandwidth of experiment.
- ~500 million events.
- 7000 files, 120TB of data
- Most data were taken in full pulse mode of the Flash ADCs
- Need to get final processing algorithms on the FPGAs in the FADCs
- Need to clean raw data of massive unused headers.
- Event Rates of 2KHz for full experiment, much higher for individual components.
- Need to move to block mode.
- Need to move to FPGA processing to compress data.
- Full DAQ chain to local raid disk, transfer to tape, and automatic processing from tape.
- Robustness issues with the system
- Handle corrupted evio data
- Problems with some FADCs getting out of sync.
- Stealth Online Data Challenge
- Exceeded the 300MB/s transfer to tape bandwidth of experiment.
- Revisit data and computing spreadsheets
- Update based on current software performance.
- Update with best estimates of raw data footprint.
- offline monitoring
- browser
- analyze data as it appears on the silo
- reconstruction results
- calibration committee
- bi-weekly meeting
- preliminary list of constants compiled
- calibration still needs to be regularized
- calibration database training
- CCDB successes
- command line interface
- SQLite form of database
- analysis results
- electron identification in the FCAL.
- pi0 peak
- proton id with tof
- proton id with dE/dx
- rho meson in pi+ pi-
- omega meson in pi+ pi- pi0
- data transfer to CMU via globus Online
- data management: event store, etc.
