Color code: (critical, news during the meeting: green, news from this week: blue, news from last week: purple, no news: black)

GPU Event display:

• Merged feature to support different backends (started a toy project over christmas to support Vulkan, and hoping to add that soon)
• Still working on Vulkan backend, no update this week.

ITS GPU Tracking and Vertexing:

• Matteo will now continue with ITS GPU tracking.

TRD Tracking

• Restored TRD GPU Tracking on Run 2 data (required some minor fixes after recent changes in TRD tracking).
• Made TRD GPU Tracking work in O2 for Run 3 data, so far only working properly with GPU Track Model (GPUTPCGMTrackParam).
• Runs through with O2 track model (TrackParCov), but attaches less tracklets. Ole is investigating. Discussed it that it might be due to incorrect initialization of the covariance.

TPC dEdx correction

• New multi-variant class implemented with GPU support, Jens will test performance in AMD GPUs in EPN.
