• CHEP talk together with Jolly got accepted.
• Presenting "proof of concept" for a variation in CMS clustering algorithm CLUE tomorrow.

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
• Created a pull-request for O2 with the following changes:
  • With the argument --PROCtimingCSV <filename> we write the output of --debug <n> to a CSV file.
  • To avoid code duplication, I also changed the way we print to the terminal (see next section).
  • The argument --PROCresetTimers was always overwritten by --runsInit, changed that.
• Tried also Gabriele's benchmarking tool. Worked out of the box.
• Next Steps:
  • Put same settings and compare with Gabriele's benchmarking tool. 
  • 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
