[Insight-users] Parallel Processing

[Luis Ibanez]

Hi Vaijanath,

We will be happy to get your algorithms in ITK.

Here is the typical process to follow in order
to include code in ITK:


1) Check that your filters are using the ITK
    coding style. you will find a PDF document
    describing the style under

    Insight/Documentation/Style.pdf


2) Make sure that your code compiles and runs.

    It may sound obvious,... but there are software
    developers out there who tend to forget
    these little details   :-)

    Provide a reasonable test for every class
    in your filters.  Test shouldn't be too
    intensive since we run them in a continuous
    basis. Typically something in the range of
    seconds would be ok.


3) About how to invoke a mpicc compiler, you
    can simply configure your CMakeLists.txt
    file in order to use a different compiler.
    The CMake CUSTOM_COMMAND is a flexible way
    to go about it.

    You might want to look at the files

       CMake/Modules/FindMPI.cmake

    and to the CMakeLists.txt file in VTK under

        VTK/Parallel

    in order to get a felling on how to configure
    a project that uses MPI.  VTK (as opposed to ITK)
    has support for MPI, therefore you will find
    a lot of useful information regarding the required
    CMake configuration.



4) The full documentation of ITK filters can be
    found at

    http://www.itk.org/Insight/Doxygen/html/classes.html

    Note that parallelism in ITK is implemented only
    for shared memory, not for distributed systems.

    The filters that support parallel execution (in the
    shared memory setup) are listed under:

    http://www.itk.org/Insight/Doxygen/html/group__MultithreadingGroup.html






Regards,



   Luis
