• DCA Fitter on GPU:
  • As tests worked, a first showcase application on an analysis task (plot attached for reference): link.
    • Currently, we need to copy the track parameters from the arrow table to construct the tracks. Ideally, this could be done on the GPU as well.
    • Will try to adapt a task (this or similar in HF, where DCA fits are a bottleneck) with the processBulk version (see below).
  • Added processBulk() CPU handler to perform simultaneous fitting (1 Fit/thread) of a vector of TrackParCovs: PR.
    • Added kernel timing. On 10000 fits, 20 blocks, and 512 threads, we are comparable with the CPU, a scaling study is planned.
• ITS Tracking on GPU:
  • No progress this week; I will start benchmarking on EPN this afternoon.
  • Re-create consistency checks
