paraDIS_lib is a library that provides the ability to create useful visualizations and detailed analysis of dumpfiles created from a ParaDIS simulation code.
paraDIS_lib's oputput consists of both a C++ library, libparadis.a, which can enable visualization and analysis of data in external tools such as VisIt, and an executable, analyzeParaDIS, which can be used to analyze and visualize a ParaDIS dumpfile.
See https://ipo.llnl.gov/technologies/paradis for more information about ParaDIS. The image displayed on the ParaDIS website was created with the analyzeParaDIS tool, which is part of paraDIS_lib.
paraDIS_lib requires g++ 4.9.2 to install. You can set the CC and CXX variables to help find the compilers as needed or simply set your PATH so that gcc and g++ are the right versions. Also required are the Boost 1.55 and tclap 1.20 libraries. By default, the Makefile assumes they are installed in the current directory as ./boost and ./tclap. However, you can also set BOOSTDIR and TCLAPDIR when compiling, something like this:
CC=/usr/apps/gnu/4.9.2/bin/gcc \
CXX=/usr/apps/gnu/4.9.2/bin/g++ \
INSTALL_DIR=./install_dir/ \
BOOSTDIR=/usr/local/tools/boost-nompi-1.55.0 \
TCLAPDIR=/g/g0/rcook/current_projects/RC_cpp_lib/tclap-1.2.0 \
make installThe boost libraries must include compiled libboost_filesystem and libboost_system libraries.
Files are installed into $INSTALL_DIR if defined, else a directory
called ./$SYS_TYPE if SYS_TYPE is defined, else a directory called
./uname -n.
paraDIS_lib builds a library which you should be able to link in as part of a plugin architecture. This has been used to build plugins for LLNL's VisIt tool in the past. Since the code is written in C++, a C-style interface is also provided and can be accessed by including paradis_c_interface.h.
This is what most users will use. Run analyzeParaDIS --help to get a
list of options and usage. Most commonly you are going to run it like
this: analyzeParaDIS --full <dumpfile.data> This will create VTK
files which can be viewed independently or all at once by using LLNL's
VisIt tool by opening the .visit file. Much can be learned also by
viewing the OUTPUT_DIR/summary.txt file that gets created.
I wrote all the code in this library in collaboration with Meijie Tang, Moono Rhee, Sylvie Aubry, Tom Arsenlis, Gregg Hommes and the rest of the ParaDIS team at LLNL. What a fun project!
