More Bandwidth reduction in HLT2 IFT SMOG2 lines
A few changes to HLT2 lines to reduce bandwidth taken in the FULL stream when injecting Argon:
- Redistribution of lines between turbo and full according to discussions at IFT WG meeting
- Caveat: calibration in `hlt2_ift_smog2_chargedPID` and Omega&Cascade lines are not sent to Turbo for the moment. Their rate is reduced by filtering on hlt1 trigger lines.
- Selection and changes in the lines:
- Increased PID tag requirement in muon id line (to reduce high rate) to 0 and min pt probe to 200. Rate reduced from 0.8kHz to 0.33kHz
- Eta_c selection adapted to modifications in HLT1 line, changed in this MR Allen!1523 (merged). Rate is reduced from 1kHz to 0.8kHz.
- Omega&Cascade lines: add filter on `Hlt1SMOG2L0ToppiDecision`, rate of Xi line reduced from 0.47132kHz to 0.35kHz
- Generic lines: require `hlt1_filter_code` in single track high pT lines (requiring a SMOG2 HLT1 single track line) and in diKS and diLambda lines (requiring the hlt1 ks or lambda
- Remove persistReco in physics line of phi->KK (saves ~0.2Gb/s of bandwidth)
- All lines are renamed with the prefix "Hlt2IFTTurbo_" and "Hlt2IFTFull_" so the stream they belong is explicit in the name
- Add a new minimum bias hlt2 line, passthrough on hlt1 decisions for CEP (low activity lines), filtering now on `
Hlt1SMOG2PassThroughLowMult5
`. This line is removed from `Hlt2IFT_SMOG2LumiPassthrough` as only `Hlt1SMOG2BELowMultElectronsDecision` will be used in the luminosity determination.
Updated estimations of rate and bandwidth:
- FULL: (6.067 +- 0.353) kHz and 0.725Gb/s (before this MR, 9kHz and 1.21Gb/s) rate_bandwidth_FULL_pAr_pp_HLT2.log
- TURBO: (2.468 +- 0.225) kHz and 0.14Gb/s (before this MR, 1kHz and 0.116Gb/s) rate_bandwidth_TURBO_pAr_pp_HLT2.log
The lines in the MR uses HLT1 lines with name changed by Allen!1523 (merged).
Note: global BW are currently not being run on a sample with Argon, so they do not include this contribution to the throughput.
I tag @samarian and @thboettc also as ift convenors so they check these changes.
