Agenda
- Announcements
- Previous Meeting (May 27, 2016)
- EVIO Parsing
- Benchmarking status
- Simulation Status
- AOT
Minutes
Attendees: David L., Adesh S., Mike W., Cristiano F., Sean D.
EVIO Parsing
- David Showed some benchmarking results for the EVIO parsing code with various levels of associated object linking enabled
- Mysterious rate drop observed when no linking is done from 12kHz to 8kHz.
- Mike noted that they had to empirically determine the optimal number of threads for the LHCb HLT
- David will work on mapping our the performance for various settings in the parsing threads and processing threads (benchmarking was always done with both set to 32)
sim-recon algorithm benchmarking
- Cristiano continues to work on mapping the performance of various algorithms using janadot
- Some discrepancies between real data and simulated data performance
- Will look into effect of LED triggers on results (particularly time spent matching tracks to calorimeter clusters)
- Sean noted that there are lots of PS triggers in the real data that should be filtered
Simulation
- Adesh is currently running 10M bggen events with incident γ energy down to %pi; threshold (global use sim1 data set only goes down to 3GeV)
- Farm jobs expected to be done by Monday morning
- Size of REST files produced is about 10 times smaller than "normal"
- Justin told Adesh this is expected due to the dominance of low energy events
- Wiki documentation is forthcoming
