With oracle VM and “13 Tev tutorial” we can ru C++ in multicore environnement (very fast) the root version of 6.18.04 running with Atlas-Open-Data-ubuntu-2020-v4.0va from Zenodo.
The 13 TeV 2025 Open data data works with root version 6.34.06 then not with this Atlas-Open-Data-ubuntu-2020-v4.0va
The 13 TeV 2025 Open data data works using Docker which have the good root version
is it a multicore option in Docker
Anaconda with uprout works well with the 2 set of data. It is incompatible with multicore and then is very slow.
