aMCfast - A fast interface between MadGraph5_aMC@NLO and APPLgrid


Since the aMCfast inteface provides a bridge between MadGraph5_aMC@NLO and APPLgrid, the packages to be downloaded and installed are the following:

  • aMCfast 1.3.0
  • MadGraph5_aMC@NLO version 2.3.0 (due to a bug this patch needs to be applied)
  • APPLgrid 1.4.70
  • Installation

    Given that MadGraph5_aMC@NLO requires to be used with gfortran v4.6 or higher, we recommend this compiler (or an equivalent one) to be adopted in the installation of all codes (see here for an example of how to set gfortran 4.7.0 as the default compiler on a CERN SLC6 or SLC5 machine).

    The installation procedure for APPLgrid and aMCfast is the standard one. Once you have downloaded the zipped souces from the links above, you just do: tar xfvz applgrid-1.4.70.tgz
    cd applgrid-1.4.70
    ./configure --prefix=/applgrid/installation/path/
    make install


    tar xfvz amcfast-1.3.0.tgz
    cd amcfast-1.3.0
    ./configure --prefix=/amcfast/installation/path/
    make install
    It is important to install first APPLgrid and then aMCfast as the latter requires the former to be properly installed. In particular, after having installed APPLgrid and before installing aMCfast, the user should set: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/applgrid/installation/path/lib
    export PATH=$PATH:/applgrid/installation/path/bin

    aMCfast and APPLgrid can be downloaded also via svn using the following commands: svn co amcfast-01-03-00 and: svn co applgrid-01-04-07

    Extra dependencies

    There are a few more external codes that need to be previously installed in order to successfully carry out the installation procedure discribed above. They are:

  • ROOT
  • FastJet
