Description

The SPI project has experienced important changes in operations, infrastructure and architecture terms in the last three years. The large amount of packages and platforms that the LCG stack supports, the set of new compilers and architectures expected by experiments and the new communities entering the project, together with the role that new file and storage systems are playing define the frame that drives the project to a new stage. Beyond the operational nature of the Librarian and Integration bi-weekly meeting that we have with the experiments, we need to review the current SPI project, its weak areas, the points not covered for our users, their expectations and the future directions the project should take in the next three years time.

The central idea of this workshop is therefore, to review the status of the project as it is right now, to establish a common strategy that will cope with the requirements of the LHC users and communities and to identify areas of interest for the rest of LHC communities that still are not using the LCG stacks.

 

Objectives to review

  • Usage of the current LCG nightlies and releases

    • Deployment on the experiments build stacks

    • Usage of the releases within their experimental models and by their user communities

    • Distribution of the software: Packaging infrastructures

      • Distribution of LCG releases in Docker containers

  • Review of the packages currently included in the LCG stacks and identification of weak points in our structure

  • Validation of the LCG releases

    • Setup of validation tests within LCGtest

  • File and storage systems

    • Usage of CVMFS/EOS for experimental builds/releases at T0

    • Distribution of CVMFS at the Grid sites (T1, T2...)

    • Relevance of docker distributions for non CVMFS aware sites

    • Role of sft.cern.ch CVMFS area: distribution to all Grid sites

  • Build systems used by experiments

    • Configuration of the build nodes with a common perspective

    • Jenkins; common points

  • Maintenance of old releases: Production against development LCG releases

    • Role of AFS if any

 

Future Objectives

  • Expectations of the experiments for the next 2-3 years

    • Evolution of the LCG stack in terms of new packages/versions

    • New compilers, OS and architectures (clang, arm, mac...)

  • Evolution of the experiments build systems in the next 2-3 years

  • New communities: BE and beyond

    • Entry ports to new projects

  • Communication forums if needed

    • Is LIM enough?, reorganization of the meeting.

  • The role of the new packaging systems within the experiments plans in the context of HSF
