Visualization : VisIT

Installation

VisIT provide the script to do all the compilation.

Download the latest script from : http://portal.nersc.gov/project/visit/releases/2.10.0/build_visit2_10_0

Script download most of dependency , If internet connection is not provides then the tar of the dependency has to be provided. Which will be identified by script. http://visitusers.org/index.php?title=Build_visit_overview for more information and flags.

wget http://portal.nersc.gov/project/visit/releases/2.10.0/build_visit2_10_0
chmod 764 build_visit2_10_0
module load gcc.5.2.0
build_visit2_10_0 --mesa --prefix /cm/shared/apps/visit/2.10
...

Following are the additional plugin that visit uses , Script is capable of downloading the components or if the specific version of plugin is required then its binary should be present.

PARALLEL Build

Parallel visit compile is simple , add the parallel flag as option in visit script.

build_visit2_10_0 --mesa --parallel --prefix /cm/shared/apps/visit/2.10

Custom mpi compilation could be mentioned in <VisIt>/src/config-site/<hostname>.cmake and it contains the variables needed to tell visit build system where it can find libraries needed to build VisIt.

     Tell the build system where to find the include paths for your MPI header files: 

  SET(VISIT_MPI_CXX_FLAGS -I/usr/lib/mpi/include)

    Tell the build system where to find your MPI libraries: 

  SET(VISIT_MPI_LD_FLAGS -L/usr/lib/mpi/mpi_gnu/lib)

    Or, if your system gets MPI libraries from multiple locations: 

  SET(VISIT_MPI_LD_FLAGS "-L/usr/lib/mpi/mpi_gnu/lib -L/some/other/path/mpi")

    Finally, tell the build system which libraries use: 

  SET(VISIT_MPI_LIBS mpi)
