-\subsection options_simgrid_configuration_gtnets Using GTNetS
-
-It is possible to use a packet-level network simulator
-instead of the default flow-based simulation. You may want to use such
-an approach if you have doubts about the validity of the default model
-or if you want to perform some validation experiments. At the moment,
-we support the GTNetS simulator (it is still rather experimental
-though, so leave us a message if you play with it).
-
-
-<i>
-To enable GTNetS model inside SimGrid it is needed to patch the GTNetS simulator source code
-and build/install it from scratch
-</i>
-
- - <b>Download and enter the recent downloaded GTNetS directory</b>
-
- \verbatim
- svn checkout svn://scm.gforge.inria.fr/svn/simgrid/contrib/trunk/GTNetS/
- cd GTNetS
- \endverbatim
-
-
- - <b>Use the following commands to unzip and patch GTNetS package to work within SimGrid.</b>
-
- \verbatim
- unzip gtnets-current.zip
- tar zxvf gtnets-current-patch.tgz
- cd gtnets-current
- cat ../00*.patch | patch -p1
- \endverbatim
-
- - <b>OPTIONALLY</b> you can use a patch for itanium 64bit processor family.
-
- \verbatim
- cat ../AMD64-FATAL-Removed-DUL_SIZE_DIFF-Added-fPIC-compillin.patch | patch -p1
- \endverbatim
-
- - <b>Compile GTNetS</b>
-
- Due to portability issues it is possible that GTNetS does not compile in your architecture. The patches furnished in SimGrid SVN repository are intended for use in Linux architecture only. Unfortunately, we do not have the time, the money, neither the manpower to guarantee GTNetS portability. We advice you to use one of GTNetS communication channel to get more help in compiling GTNetS.
-
-
- \verbatim
- ln -sf Makefile.linux Makefile
- make depend
- make debug
- \endverbatim
-
-
- - <b>NOTE</b> A lot of warnings are expected but the application should compile
- just fine. If the makefile insists in compiling some QT libraries
- please try a make clean before asking for help.
-
-
- - <b>To compile optimized version</b>
-
- \verbatim
- make opt
- \endverbatim
-
-
- - <b>Installing GTNetS</b>
-
- It is important to put the full path of your libgtsim-xxxx.so file when creating the symbolic link. Replace < userhome > by some path you have write access to.
-
- \verbatim
- ln -sf /<absolute_path>/gtnets_current/libgtsim-debug.so /<userhome>/usr/lib/libgtnets.so
- export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/<userhome>/usr/lib/libgtnets.so
- mkdir /<userhome>/usr/include/gtnets
- cp -fr SRC/*.h /<userhome>/usr/include/gtnets
- \endverbatim
-
-
- - <b>Enable GTNetS support in SimGrid</b>
-
-In order to enable gtnets with simgrid you have to give where is gtnets. (path to \<gtnets_path\>/lib and \<gtnets_path\>/include)
-
- \verbatim
- Since v3.4 (with cmake)
- cmake . -Dgtnets_path=/<userhome>/usr
-
- Until v3.4 (with autotools)
- ./configure --with-gtnets=/<userhome>/usr
- \endverbatim
-
- - <b>Once you have followed all the instructions for compiling and
- installing successfully you can activate this feature at
- runntime with the following options:</b>
-
- \verbatim
- Since v3.4 (with cmake)
- cd simgrid
- make
- ctest -R gtnets
-
- Until v3.4 (with autotools)
- cd simgrid/example/msg/
- make
- make check
- \endverbatim
-
-
- - <b>Or try the GTNetS model dogbone example with</b>
-
- \verbatim
- gtnets/gtnets gtnets/onelink-p.xml gtnets/onelink-d.xml --cfg=network_model:GTNets

- - <b>DISCLAIMER</b>
- The patches provided by us worked successfully with GTNetS found
- <a href="http://www.ece.gatech.edu/research/labs/MANIACS/GTNetS/software/gtnets-current.zip">here</a>,
- dated from 12th June 2008. Due to the discontinuing development of
- GTNetS it is impossible to precise a version number. We STRONGLY recommend you
- to download and install the GTNetS version found in SimGrid repository as explained above.
