[QEE] branch to collect contributions aiming for April12th. BW is Influenced by Allen!1372
Sitting at/above 2024-patches with commit d86c8106
NB: This MR is influenced by Allen!1372 (merged), adding some Hlt1 Jet Lines.
There are a set of Hlt2/Spruce inclusive jet lines (single and dijet) that filter on these new hlt1 jet lines, that cannot be evaluated centrally.
The jet team have locally estimated the impact of these lines on the exclusive sprucing footprint, +80MB/s (~35%) to the QEE bandwidths.
This was done before the compression changes in Moore (see: slide 4 ), so Hlt2 estimates are ~2.5 times too small to compare to current estimations.
Therefore for the table below we consider +200MB/s to Hlt2 and +80 MB/s at sprucing.
- This is an approximation, a new estimation with the same compression changes has been requested from the jet team
BW Conclusions
This MR affects the QEE streams (estimated via local evaluations):
| Process | BW Change [MB/s] |
|---|---|
| Full | +220 (~10%) |
| Turbo | -70 (~10%) |
| Spruce | +190 (~90%) |
Where the fraction is w.r.t. QEE's BWs estimated locally.
NB:
This includes the following assumptions:
- New changes to no longer compress the DstData in Moore are included, so absolute Hlt2 bandwidths are ~2.5 times larger than physical bandwidths. See: slide 4
- This includes the assumption that Allen!1372 (merged) will be merged in time.
Local BW Estimation
The local estimate below by me is not including the Hlt1 Jet line.
Evaluated with master (e264305d) on 06-Apr-24.
50k input events for Hlt2
(input events for Spruce_Concurrent = qee-full-stream retention on 50k events).

| Process | Output Events | Size (MB) | Rate (kHz) | BW (MB/s) |

Changes:
| MR | Progress | BW changes | Short description |
|---|---|---|---|
| !3155 (merged) | Merged | None | Renaming of Hlt2 line names |
| !3229 (merged) | Merged | -30 MB/s (7%) Turbo | Loosen mu_pt cuts for DY but add pid_mu cuts to keep BW constant |
| !2929 (merged) | Merged | +7.3 MB/s (2%) Turbo | TTrack Exotica search |
| !3152 (closed) | Merged | +80 MB/s (40%) Sprucing | Asym Jet lines: W->c |
| !3240 (merged) | Merged | +50-100 MB/s (25-50%) Sprucing | Use Hlt1 Jet lines to filter inclusive Hlt2 Jets. Influenced by Allen!1372 (merged) makes it difficult to estimate |
| !3242 (merged) | Merged | None | Centralise the jet builder definitions. |
| !3261 (merged) | Merged | None, but ~10 MB/s (~2%) Turbo BW once 2024 Configuration is in | Remove DiMuonNoIP trchi2 cut |
| !3248 (merged) | Merged | 30 MB/s (~5%) Turbo BW | Large increase in eff for majo2leplep lines |
NB: These estimates were evaluated before the compression changes
These MRs did not make it for the deadline.

ToDo:
-
local evaluations over 50k. -
New evaluation of the Hlt1 Jet line's impact. Been requested.
