getdp: Main Page - doxygen documentation

Some Fossies usage hints in advance:

To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies getdp-3.5.0-source.tgz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

This is GetDP, a General environment for the treatment of Discrete Problems.

Building a bare-bones version of GetDP from its source code requires a C++ compiler and CMake (http://cmake.org). By default GetDP also uses the GSL (http://www.gnu.org/software/gsl) and PETSc (http://www.mcs.anl.gov/petsc), using either real or complex arithmetic. If PETSc is available, GetDP can use SLEPc (https://slepc.upv.es/) to solve eigenvalue problems. Instead of PETsc (and SLEPc), GetDP can also use a built-in set of linear solvers derived from Sparskit Version 2 (http://www-users.cs.umn.edu/~saad/) and eigensolvers from Arpack (http://www.caam.rice.edu/software/ARPACK). Sparskit and Arpack, as well GetDP's special mathematical functions require a Fortan compiler and BLAS/LAPACK.

Build GetDP using CMake's graphical user interface

Launch CMake and fill-in the two top input fields (telling where the GetDP source directory is located and where you want the GetDP binary to be created).
Click on "Add entry" and define the variable CMAKE_PREFIX_PATH, of type "PATH", pointing to the location(s) of any external package(s) (BLAS/LAPACK, etc.) installed in non-standard directories.
Click on "Configure" and choose your compiler.
Optionally change some configuration options (re-run "Configure" every time you change some options).
Once you are happy with all the configuration options, click on "Generate".
Go to the build directory and build Gmsh using your chosen compiler.

Build GetDP from the command line

Create a build directory, for example as a subdirectory of GetDP's source directory:

mkdir build
Run cmake from within the build directory, pointing to GetDP's source directory:

cd build cmake ..
To build and install GetDP then simply type

make make install
To change build options you can use "ccmake" instead of "cmake", e.g.:

ccmake ..

or you can specify options directly on the command line. For example, you can use

cmake -DCMAKE_PREFIX_PATH=/opt/local ..

to specify the location of external packages installed in non-standard directories. You can use

cmake -DCMAKE_INSTALL_PREFIX=/opt

to change the installation directory. Or you can use

cmake -DENABLE_PETSC=0 -DENABLE_SPARSKIT=1 ..

to build a version of GetDP that uses Sparskit instead of PETSc.
You can keep multiple builds with different build options at the same time: just configure the builds in separate directories.
To see a detailed compilation log use

make VERBOSE=1
