Alice Weekly Meeting: Software for Hardware Accelerators / PDP-SRC

Wednesday 2 Apr 2025, 10:00 → 11:30 Europe/Zurich

10:00 → 10:20 Discussion

Speakers: David Rohr (CERN), Giulio Eulisse (CERN)

10:20 → 10:25 Following up JIRA tickets

Speaker: Ernst Hellbar (CERN)

10:25 → 10:30 TPC ML Clustering

Speaker: Christian Sonnabend (CERN, Heidelberg University (DE))

Framework

• Cuda / Hip thread implementation PR ongoing: https://github.com/AliceO2Group/AliceO2/pull/14117
• Cosmetic changes PR ongoing: https://github.com/AliceO2Group/AliceO2/pull/14069
  • These two will conflict, but should be easy to resolve. Have to think about how to pass streams correctly to ONNX without reloading the model everytime

 

Physics

• Ran on full sample of LHC24as (at least the one where we have the raw TFs: ~1 permille of total statistic)

• Loosing K0s, especially close to the true K0 mass

10:30 → 10:35 ITS Tracking

Speaker: Matteo Concas (CERN)

10:35 → 10:45 TPC Track Model Decoding on GPU

Speaker: Gabriele Cimador (Universita e INFN Torino (TO))

10:45 → 10:55 Efficient Data Structures

Speaker: Dr Oliver Gregor Rietmann (CERN)
