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

General:

Locally tested OpenCL compilation with Clang 14 bumping –cl-std from clc++ (OpenCL 2.0) to CLC++2021 (OpenCL 3.0) and using clang-internal SPIR-V backend. Arrow bump to 8.0 done, which was prerequesite.
- Work on bumping GCC still ongoing (by Giulio), will follow up with Clang 15 afterwards, once we are at arrow 10.

ROCm compilation issues:

Create new minimal reproducer for compile error when we enable LOG(...) functionality in the HIP code. Check whether this is a bug in our code or in ROCm. Lubos will work on this.
Another compiler problem with template treatment found by Ruben. Have a workaround for now. Need to create a minimal reproducer and file a bug report.

ITS GPU Tracking and Vertexing:

Matteo will spend 1 week working on multi-threading of ITS vertexing, then go back to GPU ITS tracking.

TPC GPU Processing

Random GPU crashes under investigation.
TPC CTF Skimming finalized.
Bug in TPC tracking on CPU depending on number of threads. 5 gives incorrect result. 1, 2, 3, 4, 6, 64, 128 seem to be ok. Investigating.
Problem in CTF decoding when input is missing (empty input is OK, but we want a fallback treatment in case the input is an empty message, not only empty header).
Problem in TPC tracking, when some TPC pad rows in a sector have issues, track merging across these pad rows seems not to work correctly. Investigating.
