Minutes : Florence Ranjard

      1.  LHCb presentation at LHC++ workshop (P.Mato)(pdf)

• Pere will have 30 minutes at the LHC++ workshop to present the LHCb requirements :
  •     LHC++ will be used in the Algorithms (i.e. minimization) and Services (i.e. i/o)
• ===> integration issues:
  • package structure: dependencies
  • interface quality: must be good
  • Run-time libraries : shareable libraries.
  • No static storage.
• ===> compilation issues:
  •     LHCb is using g++ compiler on all platforms to use namespace and STL : so we need
    LHC++ packages compiled with this compiler on all platforms (rsplus, hpplus, Linux).
• We need a smooth transition between CERNLIB and LHC++:
  • A page on the Web to give the NagC replacement of CERNLIB routines.
  • Better examples how to use commercial packages in the HEP environment.

2. C++ Codind Convention Summary (P.Binko)

• Changes submitted to the SPIDER-Codecheck are summarized in the minutes of the infrascture meeting
  held on 18 march 1999.

          3. Work in Clermont-Ferrand   and related questions (V.Breton)

• Clermont is working on a Clustering algorithm in ECAL.
• The current version of GAUDI has been downloaded on a PC , it is running using Visual C++.
• The NagC library is not yet used by GAUDI
• CERN will provide the NagC library as any LHC++ components to all HEP laboratories for free.
• Vincent will be the french LHCb representative to the IN2P3 computing workshop.
• Vincent suggested to improve our communication:
  • advertise reactions to Pere's talk at the LHC++ workshop.
  • announce important meetings such as : LHC++ workshop, Geant4 technical steering board.
• There is not yet any specific working group such as Reconstruction or Simulation.
• Small workshops in specific domain could be organized to help in OO design
