NextGenTrigger Task 1.7

• Implementing our SoA code in MadGraph, together with
  • Stefan Roiser
  • Daniele Massaro
• Used NGT cluster and it's GPUs for Christian's benchmarks (2x Nvidia, 2x AMD)
• Will get next update on Thursday (January 15)

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
• Implemented SoA in:
  
  • SectorTracker
    • GPUTPCBaseTrackParam
    • GPUTPCTrackParam
    • GPUTPCTracklet
• Switch between AoS and SoA is now just one flag.
• AoS with our new data layout abstraction has zero overhead to the old code
• Made some changes to SoA/AoS code to make it more user-friendly.
• Next Steps:
  
  • Make better use of SoA to improve performance
  • Try David's suggestion
