LHC Software Production Infrastructure Conclusions (1/2) • Major investment started since 1999 in new software technology : – OOA/D – Java – SCa. M • SPS-2001 and CESAR projects are using, improving and validating these choices M. Vanden Eynden SL/CO 2 nd LHC Controls Project Workshop CERN, April 5, 6 2001 23

LHC Software Production Infrastructure Conclusions (2/2) • How this software production environment will be used is under the responsibility of the software projects ! – “state of the art” environment but … – Each component of this infrastructure shall be used in the light of the size and complexity of each software project • LHC Sector test in < 36 months – What is described today is our strategic investment for injecting in LHC in 2004 – Platforms and OS have still to be chosen – LHC Software development could start by end 2002 • There is no technology shift without Training M.
