  7. Goal • To make our research* productive • To make technology transfer efficient *computational experiments Vancouver School & Workshop

  8. One Week Technology Transfer a b c Vancouver School & Workshop

  9. Madagascar Design Principles • Document computational experiments • Old experiments are regression tests • New experiments become unit tests Test Driven Development Vancouver School & Workshop

  10. This Presentation • Introductory remarks • History • Goal • Design principles • Installation and compilation • Downloading • Compiling with SCons • File structure Vancouver School & Workshop

  11. Downloading Madagascar • Stable version • madagascar-0.9.3 • SourceForge • Unstable (development) version • svn co https://svn.sourceforge.net/svnroot/rsf/trunk rsf • Update withsvn update • Commit withsvn commit(developers) • Browse at http://svn.sourceforge.net/viewvc/rsf/ • Subversion facilitates collaboration and version control Vancouver School & Workshop

  12. Cumulative Subversion Access Vancouver School & Workshop

  13. SCons (Software Construction) • “make” replacement • Built-in “autoconf/automake” functionality • Written in • Open-source http://www.scons.org • Used for compiling Madagascar • Used for managing processing flows SCons is an easier, more reliable and faster way to build software. Vancouver School & Workshop

  14. From Tim O’Reilly’s blog “O’Reilly Radar” Vancouver School & Workshop

  15. Installing from Source • Unpack • tar xvzf madagascar-0.9.3.tgz • Prerequisites • Install Python and SCons if necessary • Set environmental variables • Build • scons config (generates config.py) • scons install • http://rsf.sf.net/wiki/index.php/Installation $RSFROOT root of installation $PYTHONPATH add $RSFROOT/lib $DATAPATH home for binary files Vancouver School & Workshop
