NextGenTrigger Task 1.7

• CHEP talk together with Jolly got accepted.
• Co-Supervision of a summer student. Topic: Imrpove clustering algorithm CLUE.

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
    • GPUTPCTrack
• Benchmarking:
  • Two independent measurements for each of the 4 NGT GPUs (standlaone + profiler)
  • Integrated in CI-pipeline with a comparison to the unaltered code
  • Results are now much more consistent, at least with the profiler
• Ran all the benchmarks with and without monitoring: results looked very consistent.
• Next Steps:
  • Build and run O2 with C++26 compiler to integrate reflections (needed for CHEP benchmark) 
  • Write minimal reproducer for the (weird) behavior I observed with AMD W7900 and custom .par file.
  • Make better use of SoA to improve performance
  • Try David's suggestion
