Platforms supported by LHCb production software

Source code and binaries for supported platforms are available on disk (in AFS directory /afs/cern.ch/lhcb/software/releases - $LHCBRELEASES), and in the form of tar file distribution kits. The following platform+compiler combinations are supported. See also MultiPlatform support for Grid applications

Old production platform (binary distribution available in optimised mode, mainly for use on the Grid, no longer available for Online projects)

  • CERN Scientific Linux 3 (SLC3) with gcc 3.2.3 compiler (CMT configurations slc3_ia32_gcc323, slc3_ia32_gcc323_dbg)
    • Please note that, for releases in October and November 2006 (LHCb v21r8 to v21r11) binaries are built with the flags -msse2 -mfpmath=sse so they will not work on older machines that do not support the sse2 instruction set (e.g. Pentium III, AMD Sempron)

Production platform (binary distribution available in optimised and debug modes)

  • CERN Scientific Linux 4 (SLC4) with gcc 3.4.* compiler in 32-bit mode (CMT configurations slc4_ia32_gcc34, slc4_ia32_gcc34_dbg)
    • Using 32-bit compatibility libraries on systems booted with 64-bit SLC4 (e.g. CERN lxplus)
  • CERN Scientific Linux 4 (SLC4) with gcc 3.4.* compiler in 64-bit mode (CMT configurations slc4_amd64_gcc34, slc4_amd64_gcc34_dbg)

Development platform (binary distribution available in debug mode)

  • Windows with Visual Studio 7.1 compiler (CMT configuration win32_vc71_dbg)

Future platforms

  • A port to the gcc 4.1.* compiler is in preparation
