NextGenTrigger Task 1.7

• Presented at two Workshops:
  • https://indico.cern.ch/event/1557810/
  • https://indico.cern.ch/event/1590675/
• Started implmenting our SoA in MadGraph, together with
  • Stefan Roiser
  • Daniele Massaro

Implement NGT SoA Code in O2 standalone benchmark

• Working on this fork of the AliceO2 repo, with a CI pipeline:
  • Running on NGT hardware with 4 different GPUs (Nvidia and AMD)
  • Extended CI-pipline to fail if GPU.out changes
• Changed the SoA / AoS code to better fit ALICE O2
• Implemented SoA in:
  
  • SectorTracker
    • GPUTPCBaseTrackParam
    • GPUTPCTrackParam
    • GPUTPCTracklet
• Performance still same (or maybe 2% slower)
• Next Steps:
  • Check if AoS has no overhead due to the new abstraction
  • Make better use of SoA to improve performance
