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

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

  • CERN Scientific Linux 3 (SLC3) with gcc 3.2.3 compiler (CMT configurations slc3_ia32_gcc323, slc3_ia32_gcc323_dbg)
    • Please note that, from October 2006 (LHcb v21r8) 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)

Next 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 (as currently foreseen on CERN lxplus)

Development platform (binary distribution available in debug mode)

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

Future platforms

  • CERN Scientific Linux 4 (SLC4) with gcc 3.4.* compiler in 64-bit mode (CMT configurations slc4_amd64_gcc34, slc4_amd64_gcc34_dbg)
    • Currently being debugged (problems with random number initialization)
