Abstract: The report presents a number of news and updates of the ALICE computing for RUN2 and RUN3.
This includes:
— implementation in production of a new system EOS;
— migration to the file system CVMFS to be used for storage of the software;
— the plan for solving the problem of “Long-Term Data Preservation”;
— overview of the concept of “O square”, combining offline and online data processing;
— overview of the existing models to use the virtual clouds for ALICE data processing.
Innovations are shown on the example of the Russian sites.
