0001 T\ :sub:`R`\ ENTo
0002 =================
0003 *Reduced Thickness Event-by-event Nuclear Topology*
0004 
0005 T\ :sub:`R`\ ENTo is a simple, fast model for the initial conditions of high-energy nuclear collisions (pp, pA, AA).
0006 `PRC 92 011901 <http://journals.aps.org/prc/abstract/10.1103/PhysRevC.92.011901>`_ / `arXiv:1412.4708 [nucl-th] <http://inspirehep.net/record/1334386>`_ formally presents the model and preliminary results.
0007 The code is `publicly available on github <https://github.com/Duke-QCD/trento>`_.

0014 Quickstart
0015 ----------
0016 First, install the dependencies: a C++11 compiler, Boost, and optionally HDF5.
0017 Then download the trento source and compile with CMake::
0018 
0019    mkdir build && cd build
0020    cmake ..
0021    make install
0022 
0023 See :doc:`installation` for details.
0024 
0025 Generate ten lead-lead events using default settings::
0026 
0027    trento Pb Pb 10
0028 
0029 ``trento`` prints the following event properties to stdout: event number, impact parameter, number of participants, total entropy, and eccentricity harmonics 2--5.
0030 To additionally save the event profiles to an HDF5 file::
0031 
0032    trento Pb Pb 10 -o events.hdf
0033 
0034 See :doc:`usage` and :doc:`examples` for complete documentation.
