    Intel software tools on AFS

    present: Pawel, Jan

    IT OpenLab provides Intel compilers (C,C++,Fortran) and performance analysis tools (e.g VTune). These are used by BE and PH-SFT, in particular from the Geant-V project. The software is stored on AFS in /afs/cern.ch/sw/IntelSoftware/ . AFS support recently enabled warning for overloaded volumes, these occasionally get triggered from the Intel software project. Actual reason for overload is unclear (not enough logging on the AFS service to look after the fact, OpenLab only provides the software but does not run this heavily itself).

    AFS support would like to push the "software distribution" use case to CVMFS, at least for parallel access from managed machines (access from personal machines is easier into AFS, but assumed to be less critical - expect that mission-critical work is performed on managed machines)

    • would need to get an idea of actual users and access patterns (could look at license uptake via license server? instrument the setup script? )
      • with that, could create user mailing list (announce new releases, switch to CVMFS, discuss use cases), encourage self-subscription by other interested parties
    • short-term: converting the existing AFS volumes under /afs/cern.ch/sw/IntelSoftware/ to readonly and replicating them might be enough to make the warnings disappear. Suggest to go for fine granularity, i.e. one volume per product+release - this gives (coarse) usage logging for free, but even the existing volume layout would benefit
    • mid-term: try to install new releases in parallel on AFS and CVMFS. Contact for CVMFS is S.Traylen, would need estimates for #files, amount of data and increase rate..
      • CVMFS might proved better logging?

    There might be synergies with other software providers:

    • PH-SFT provides additional (free) compilers as part of the "external" software packages (and are already being contacted for CVMFS)
    • IT still has some Fortran compilers on AFS ( /afs/cern.ch/sw/fortran/ )
