The new address for the Brunel documentation is:


Brunel is the LHCb reconstruction program, based on the Gaudi framework. It is developed within the context of the reconstruction project. Please refer to the project web pages for details of the project organization (meetings, mailing lists, contact persons etc.)

Reference documentation
Documentation relating to each release of Brunel is obtained by following the links in the table below. Here you can access directly the documentation of the most recent release, and the complete set of release notes. A F.A.Q. is under construction

Supported platforms and compilers
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:

  • Scientific Linux CERN 3 (SLC3) with gcc3.2.3 compiler
  • Scientific Linux CERN 4 (SLC4) with gcc3.4.* compiler
  • Windows with VC 7.1 compiler

Note that the binaries are built using sse2 extensions. They will not work on older machines that do not support the sse2 instruction set (e.g. Pentium III, AMD Sempron)

Available versions
Linux and Windows builds of the following versions are available on disk in $LHCBRELEASES. Versions marked as obsolete may be archived (removed from disk) at short notice, to make space for newer versions
