NextGenTrigger Task 1.7

• Supervising a student to work an a CMS clustering algorithm.
  • We have a first standalone c++ / alpaka version.
  • Next step: Integration in the CLUEstering algorithm (CMS clustering algo)

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
• Make better use of SoA to improve performance
  • Changed a few things about GPUTPCBaseTrackParam, but performance got only worse...
• Next Steps:
  • Generate GPU parameters .csv file for SoA and to see if the optimal parameters are different.
