The deal.II license

- -

- The deal.II library has been placed under an Open - Source license, in the sense advocated by the Open Source - Initiative. You are thus free to copy and use it, and you have - free access to all source codes. However, deal.II - is not in the public domain, it is property of and copyrighted by - the deal.II authors, and there are restrictions - on its use. We will give some hints on license issues first. The - legally binding license is the Q Public - License (QPL) at the bottom of this page. Furthermore, deal.II - distributions come bundled with some third party software for which - the deal.II authors do not own the copyright. The licenses of these - parts are discussed below. - -

- In this document, as well as in the program files, the terms - authors of deal.II and - deal.II authors generally refer to the - principal authors of the library. These are Wolfgang - Bangerth, Timo Heister, and Guido Kanschat. -

- - - -

Restrictions on and commercial use of the library

- -

- - deal.II is distributed under the Open Source - license called the Q Public License (or "QPL") listed - in full below. Essentially, an interpretation of this license is - that you can use the library free of charge for developing your own - programs. However, if you plan to distribute these programs to others, - certain restrictions are imposed by the QPL. - -

- - In non-legal terms, the license stipulates that if you want - to give your program to someone else in whatever form (including as - a binary executable), you have to make the entire source code of - your own program and all modifications to the deal.II library - available free of charge as well. - -

- - We recognize that giving away the source code may be an - unacceptable restriction in a commercial setting. As the owners of - the sources, we are able to grant you a differently licensed version - of the deal.II library that does not contain this - requirement, and we are very much willing to negotiate the terms of - such a license. Please contact the authors of the library if you are - interested in commercial use of deal.II. - - - -

Referencing the library

- -

- In addition to the terms imposed by the QPL, we ask for the - following courtesy: -

- - This is the usual, fair way of giving credit to contributors to a - scientific result. In addition, it helps us justify our effort in - developing deal.II as an academic undertaking. - -

- - We keep a list of publications - using deal.II. Feel free to let us know about your publications. - - - -

Parts of the deal.II distribution under a separate license

- - - Some of the files in the contrib/ subdirectory are by - other people, and are distributed under separate licenses. These - files are not part of the deal.II library, but - they are part of our distribution. They are generally available for - use in non-commercial academic settings. For commercial use and if - you want to distribute your codes, please consult the licenses of - these parts of the deal.II distribution. We made sure that those parts of the - distribution for which the license is not entirely free for all uses can be - disabled upon configuration of deal.II without - unduly restricting the functionality of the rest of the - library. - -

- - In particular, these are libraries that we distribute in the - contrib/ subdirectory, courtesy of their authors: -

Porting deal.II to new systems

- -

- deal.II uses very few system dependent - features. Consequently, there is a good chance that it might also run on other - systems besides the ones listed in the - ReadMe file. Nevertheless, - there are cases where some adjustments are necessary. -

- - -

- Basically, all the setup of the specifics or a system is done in the - ./configure script that is run first. This script finds out about - operating system, processor, and the like, and then goes on testing - whether certain features are present, or if their absence can be - worked around. - ./configure is not made for human eyes. It is in fact only a - script generated by the autoconf program from the files - configure.in and aclocal.m4 in the top-level directory of - deal.II. The first contains the order in which - macros are called that test for features, interspersed by shell - script snippets that do actions depending on the results of the - macros. The second file contains the user-defined macros used in - configure.in (most macros are already predefined by autoconf). - To understand how all this works together, you will have to have some, though - not a whole lot of, - knowledge of both Unix shell scripting as well as of autoconf -

- -

- At the end of running ./configure, it creates output files by - replacing all occurrences of variables like @var@ in input files - by the value of the respective environment variable in - the configure shell script. By convention, input files have a - file ending .in; the two most important input/output file pairs - are common/Make.global_options - and common/Make.global_options.in as well as - include/deal.II/base/config.h.in - and include/deal.II/base/config.h. -

- - - -

Quick porting

- -

- If you find something that does not work on your system, then the - quickest way to make deal.II run on your system - is to run configure and change things in - common/Make.global_options by hand so that it works for - you. The downside is that - this file is overwritten next time you run ./configure. -

- -

- Most often, problems on new systems are caused by the compiler not - accepting certain flags, crashing or producing invalid code on - optimization flags, not supporting shared libraries, and the like. - All these problems can be solved by changing - common/Make.global_options, e.g. by setting the variable - enable-shared to no, or by changing the compiler flags in - the variables CXXFLAGS.g (for debug mode) or CXXFLAGS.o (for - optimized mode). The most important variables in - common/Make.global_options are - listed here. -

- - - -

Portable porting

- -

- While the measures shown above make deal.II run - on your system, it does not help other users. Neither does it mean - that the next version will run on your system unless you do the same - changes over again. There are basically two ways to help us make - deal.II run on your system by default: -

    Selecting optional behavior

    You can give several flags to ./configure:
      -
    • -

      - --enable-shared: Compile the files of deal.II into - shared libraries, rather than statically linked - libraries. Enabling this option saves disk space, link time and - start-up time, so this is the default. Some systems - might not support shared libraries, in which case you should - call ./configure with the parameter - --disable-shared. -

      - -
    • -

      - --enable-threads: This flag indicates that those - parts of the library that support this compute in parallel, - using multiple threads, making programs significantly faster on - machines with multiple cores or processors. The default is to - use multiple threads since most machines today have several - processor cores. If this is not desired, - use --disable-threads. - -

    • -

      - --enable-mpi: If given this - flag, ./configure chooses mpiCC - and mpicc as the C++ and C compilers, respectively, - unless the $CXX and $CC environment - variables have specifically been set to something else. If these - compilers exist and indeed support MPI, then this also switches - on support for MPI in the library. -

      - -
    • -

      - --with-cpu=...: Enable specific optimization - flags for a particular processor. Programs compiled with these options - might not execute on another system, but may be faster on the - particular CPU selected. -

      - -

      - For a complete list of supported values of this switch, you may - take a look at the file aclocal.m4 in the top-level - directory. However, the most commonly used value - is --with-cpu=native, indicating that the compiler - should determine the CPU we are running on by itself and - optimize for it. -

    - In order to generate partitionings of triangulations, we have - functions that - call METIS library. METIS is a library that - provides various methods to partition graphs, which we use to - define which cell belongs to which part of a - triangulation. The main point in using METIS is to generate - partitions so that the interfaces between cell blocks are as - small as possible. This data can, in turn, be used to - distribute degrees of freedom onto different processors when - using PETSc and/or SLEPc in parallel mode. -

    - -

    - As with PETSc and SLEPc, the use of METIS is optional. If you - wish to use it, you can do so by having a METIS installation - around at the time of calling - ./configure by either setting - the METIS_DIR environment variable denoting the - path to the METIS library, or using the - --with-metis flag. -

    - -

    - (deal.II) version 7.2 (and higher) support - METIS 5.x.x only; earlier releases are no longer - supported.

    BLAS, LAPACK
    - -

    If --with-blas=blasname and/or - --with-lapack=lapackname is given, provide wrappers - around some of the BLAS and LAPACK functions, and link with the - respective libraries. It will make sure that we link with the - required FORTRAN libraries. If no argument is given to - --with-blas, then a BLAS library - libblas.a or libblas.so is searched for - in the default locations of your system, and similarly for LAPACK.

    - -

    If your BLAS or LAPACK libraries are not in the standard search - path of your linker, you have to tell the linker where to find them. - The path is not given as an argument to - --with-blas. Rather, you set the variable - LDFLAGS accordingly or make sure that the path is in - your LD_LIBRARY_PATH or similar. For details, please - look up the documentation of your linker. An example configuration - for Linux is:

    -
    -    ./configure --with-blas=myblas LDFLAGS=-L/my/lib/
    -    
    -

    This example will search for a library - libmyblas.a or libmyblas.so in the - directory /my/lib and elsewhere in the system library - paths.

    - -

    Some versions of BLAS and LAPACK need additional libraries - to be linked with. Such an example is the - automatically tuned - linear algebra software (ATLAS). The BLAS version of this - package also needs declarations from libatlas.a, - so it must be included. Using the standard library names of - atlas, the include for BLAS reads -

    -    ./configure --with-blas='f77blas -latlas'
    -    
    - assuming that the library files libf77blas.a and - libatlas.a or the respective shared libraries - *.so are in libraries included in - LD_LIBRARY_PATH. LAPACK generated by ATLAS is - included in a similar fashion.
