7 It is possible to use a packet-level network simulator
8 instead of the default flow-based simulation. You may want to use such
9 an approach if you have doubts about the validity of the default model
10 or if you want to perform some validation experiments. At the moment,
11 we support the GTNetS simulator (it is still rather experimental
12 though, so leave us a message if you play with it).
15 To enable GTNetS model inside SimGrid it is needed to patch the GTNetS simulator source code
16 and build/install it from scratch
19 - <b>Download and enter the recent downloaded GTNetS directory</b>
22 svn checkout svn://scm.gforge.inria.fr/svn/simgrid/contrib/trunk/GTNetS/
27 - <b>Use the following commands to unzip and patch GTNetS package to work within SimGrid.</b>
30 unzip gtnets-current.zip
31 tar zxvf gtnets-current-patch.tgz
33 cat ../00*.patch | patch -p1
36 - <b>OPTIONALLY</b> you can use a patch for itanium 64bit processor family.
39 cat ../AMD64-FATAL-Removed-DUL_SIZE_DIFF-Added-fPIC-compillin.patch | patch -p1
42 - <b>Compile GTNetS</b>
44 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.
48 ln -sf Makefile.linux Makefile
54 - <b>NOTE</b> A lot of warnings are expected but the application should compile
55 just fine. If the makefile insists in compiling some QT libraries
56 please try a make clean before asking for help.
59 - <b>To compile optimized version</b>
66 - <b>Installing GTNetS</b>
68 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.
71 ln -sf /<absolute_path>/gtnets_current/libgtsim-debug.so /<userhome>/usr/lib/libgtnets.so
72 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/<userhome>/usr/lib/libgtnets.so
73 mkdir /<userhome>/usr/include/gtnets
74 cp -fr SRC/*.h /<userhome>/usr/include/gtnets
78 - <b>Enable GTNetS support in SimGrid</b>
80 In order to enable gtnets with simgrid you have to give where is gtnets. (path to \<gtnets_path\>/lib and \<gtnets_path\>/include)
83 cmake . -Denable_gtnets=ON -Dgtnets_path=/<userhome>/usr
86 - <b>Once you have followed all the instructions for compiling and
87 installing successfully you can activate this feature at
88 runntime with the following options:</b>
97 - <b>Or try the GTNetS model dogbone example with</b>
100 gtnets/gtnets gtnets/onelink-p.xml gtnets/onelink-d.xml --cfg=network_model:GTNets
104 A long version of this <a href="http://gforge.inria.fr/docman/view.php/12/6283/GTNetS HowTo.html">HowTo</a> it is available
107 More about GTNetS simulator at <a href="http://www.ece.gatech.edu/research/labs/MANIACS/GTNetS/index.html">GTNetS Website</a>
111 The patches provided by us worked successfully with GTNetS found
112 <a href="http://www.ece.gatech.edu/research/labs/MANIACS/GTNetS/software/gtnets-current.zip">here</a>,
113 dated from 12th June 2008. Due to the discontinuing development of
114 GTNetS it is impossible to precise a version number. We STRONGLY recommend you
115 to download and install the GTNetS version found in SimGrid repository as explained above.
117 \section pls_simgrid_configuration_ns3 Using NS3
119 It is possible to use discrete-event network simulator <a href="http://www.nsnam.org/">(ns-3)</a> for Internet systems
120 instead of the default one.
123 To use ns3 model inside SimGrid you have to install at least the version 3.10 of ns3 simulator.
126 - <b>Download and enter the lateast release (here the 3.12.1)</b>
129 http://www.nsnam.org/release/ns-allinone-3.12.1.tar.bz2
130 tar -xf ns-allinone-3.12.1.tar.bz2
131 cd ns-allinone-3.12.1/ns-3.12.1/
134 - <b>Configure, make and install ns3</b>
137 ./waf configure --prefix="ns-3_install_directory"
142 After install ns-3 you should have directories into your "ns-3_install_directory":
147 You also need to add to the LD_LIBRARY_PATH : "ns-3_install_directory/lib".
149 - <b>Enable ns-3 support on SimGrid</b>
151 In order to enable ns-3 with simgrid you have to give where is ns-3 to the simgrid configuration command. (path to \<ns3_path\>/lib and \<ns3_path\>/include)
154 cmake . -Denable_ns3=ON -Dns3_path=<ns3_path>
157 With the output of the configuration you can see if ns-3 is detected by included the directory to flags.
160 Configuration of package `simgrid' on arch (=4):
162 SITE : Linux_2.6.38-11-generic_x86_64
163 Release : simgrid-3.6.1
165 Compiler: c++ : /usr/bin/c++
167 Compiler: c : /usr/bin/gcc
170 CFlags : -O3 -finline-functions -funroll-loops -fno-strict-aliasing -L/usr/lib/x86_64-linux-gnu -I/usr/include
171 -L/home/navarrop/Install/ns3-3.10/lib -I/home/navarrop/Install/ns3-3.10/include -g3 -D_NS3_3_10
172 CPPFlags: -I/home/navarrop/Install/ns3-3.10/include -L/home/navarrop/Install/ns3-3.10/lib
175 Compile NS-3 : 1 ---------------------> Be sure this option is "1" otherwise ns-3 is not activated
177 NS-3 path : /home/navarrop/Install/ns3-3.10
191 Simgrid dependencies: -lm -lpcre -lpthread -lns3 -lrt
192 Gras dependencies : -lm -lpthread -lrt
195 INSTALL_PREFIX: /usr/local
198 -- Build files have been written to: /home/navarrop/workspace/simgrid/build
201 Now you can compile SimGrid
206 Then you can see if ns-3 is well activated by testing
