looking forward improvements
main changes by Daniel:
- triplet seeding search windows are based on UT momentum estimate for high multiplicity events (empirically found to work better for those)
- triplet seeding is done in one kernel, best triplet candidates selected from all triplet searches
- track forwarding to X is also done in one kernel
- precalculated UV windows (per UT track) are used for calculating finer UV windows (per scifi track seed)
- improve throughput of velo search by triplet
main changes by Dorothea: make result deterministic, i.e. tracks -> efficiencies don't depend on execution order
- number of allowed SciFi tracks =
# of UT tracks found x factor - track container accessed through UT track index during x-hit collection
- x filter selects best candidates per UT track based on quality and saves those up to a certain cut-off
- during uv-hit collection, track container is accessed per event
- much less memory is required for the track containers
both changes resulted in lower ghost rate and higher throughput
