Installation

============



    Requirements:



    To install TNL, you need:



    cmake 3.4 or later (https://cmake.org/download/)

    GNU g++ 4.8 or later (https://gcc.gnu.org/)

    CUDA 8.0 or later (https://developer.nvidia.com/cuda-downloads)



    For image processing problems, you may optionaly install:

    DCMTK (http://dicom.offis.de/dcmtk.php.en)

    libpng (http://www.libpng.org/pub/png/libpng.html)

    libjpeg (http://libjpeg.sourceforge.net/)



    The latest release of TNL can be downloaded as:



    wget tnl-project.org/data/src/tnl-0.1.tar.bz2



    Unpack it as:



    tar xvf tnl-0.1.tar.bz2

    cd tnl-0.1



    Executing command



    ./install



    will install TNL to a folder ${HOME}/.local . You may change it by



    ./install --prefix=<TNL prefix>



    During the installation, TNL fetches latest version of Gtest and install it only 

    locally to sub-folders Debug and Release. At the end of the installation, the

    script is checking if the prefix folder is visible to your bash and your linker.

    If not, it informs you how to change your ${HOME}/.bashrc file to fix it.



How to write a simple solver

============================



To implement your own solver:



    Create and go to your working directory



    mkdir MyProblem

    cd Myproblem



    Execute a command tnl-quickstart



    tnl-quickstart



    Answer the questions as, for example, follows



    TNL Quickstart -- solver generator

    ----------------------------------

    Problem name:My Problem

    Problem class base name (base name acceptable in C++ code):MyProblem

    Operator name:Laplace



    Write your numerical scheme by editing a file



    Laplace_impl.h



    on lines:

        34, 141 and 265 for 1D, 2D and 3D problem respectively with explicit time discretization

        101, 211 and 332 for 1D, 2D and 3D problem respectively with (semi-)implicit time discretization

    Compile the program by executing



    make



    for CPU version only or 

   

    make WITH_CUDA=yes



    for a solver running on both CPU and GPU. Run it on your favourite HW architecture by executing



    ./MyProblem



    and following the printed help.
