\subsubsection faq_intro3 What cmake need?
CMake needs some prerequists like :
+
+For Unix and MacOS:
\li make
+ \li perl and libpcre
\li c, c++ and java compiler regards to developers
\li ccmake for graphical used of CMake
\li cmake <a href="http://www.cmake.org/cmake/resources/software.html">(download page)</a>
+For Windows :
+ \li cmake 2.8 <a href="http://www.cmake.org/cmake/resources/software.html">(download page)</a>
+ \li perl strawberry <a href="http://www.strawberryperl.com/download/5.12.2.0/strawberry-perl-5.12.2.0.msi">(download page)</a>
+ \li pcre-7.0 <a href="http://sourceforge.net/projects/gnuwin32/files/pcre/7.0/pcre-7.0.exe/download">(download page)</a>

If you want to test before make a commit you can simply make "ctest -D Experimental" and then you can visualize results submitted into Cdash. <a href="http://cdash.inria.fr/CDash/index.php?project=Simgrid">(Go to Cdash site)</a>.

+You can also exchange data between Process using lua. for that, you have to deal with lua task as a table,
since lua is based itself on a mechanism of tables,
so you can exchange any kind of data (tables, matrix, strings,…) between process via tasks.
Since v3.4, the use of <a href="http://ruby-lang.org">ruby</a> in simgrid is available for the MSG Module.
you can find almost all MSG functionalities in Ruby code, that allows you to set up your environment, manage tasks between hosts and run the simulation.
-\dontinclude ruby/MasterSlave.rb
\subsubsection faq_binding_ruby_example Master/Slave Ruby Application
for each process method(master and slave in this example), you have to associate a ruby class, that should inherit from <i>MSG::Process</i> ruby class,
with a 'main' function that describe the behaviour of the process during the simulation.
\endverbatim
\li Master code
-\until end_of_master
+\verbatim
+class Master < MSG::Process
+ # main : that function that will be executed when running simulation
+
+ def main(args) # args is an array containing arguments for function master
+ size = args.size
+ for i in 0..size-1
+ MSG::info("args["+String(i)+"]="+args[i])
+ end
+
+ raise "Master needs 3 arguments" if size < 3
+ numberOfTask = Integer(args[0])
+ taskComputeSize = Float(args[1])
+ taskCommunicationSize = Float(args[2])
+ slaveCount = Integer(args[3])
+
+ # Creates and sends the tasks
+ for i in 0..numberOfTask-1
+ task = Task.new("Task_"+ i.to_s, taskComputeSize , taskCommunicationSize);
+ mailbox = "slave " + (i%slaveCount).to_s
+ MSG::info("Master Sending "+ task.name + " to " + mailbox + " with Comput Size " +
+ task.compSize.to_s)
+ task.send(mailbox)
+ MSG::info("Master Done Sending " + task.name + " to " + mailbox)
+ end
+
+ # Sending Finalize MSG::Tasks
+ MSG::info("Master: All tasks have been dispatched. Let's tell everybody the computation is over.")
+ for i in 0..slaveCount-1
+ mailbox = "slave " + i.to_s
+ finalize_task = Task.new("finalize",0,0)
+ finalize_task.send(mailbox)
+ end
+ MSG::info("Master : Everything's Done")
+ end
+end
+\endverbatim
+
the class MSG::Task contains methods that allows the management of the native MSG tasks.
in master ruby code we used :
- <i>MSG::Task.name</i> : to get the task's name.
\li Slave code
-\until end_of_slave
+\verbatim
+class Slave < MSG::Process
+
+ def main(args)
+ mailbox = "slave " + args[0]
+ for i in 0..args.size-1
+ MSG::debug("args["+String(i)+"]="+args[i])
+ end
+
+ while true
+ MSG::info("Slave '"+ mailbox +"' waiting for new task");
+ task = Task.receive(mailbox)
+ if (task.name == "finalize")
+ break
+ end
+ task.execute
+ MSG::info("Slave '" + mailbox + "' done executing task "+ task.name + ".")
+ end
+ MSG::info("I'm done, see you")
+ end
+end
+\enverbatim
to receive a task, we use the method <i>MSG::Task.receive(mailbox)</i> that return a MSG:Task object (received task).
\li Main chunk
-\until MSG.exit
+
+\verbatim
+require 'simgrid'
+include MSG
+(...)
+
+if (ARGV.length == 2)
+ MSG.createEnvironment(ARGV[0])
+ MSG.deployApplication(ARGV[1])
+
+else
+
+ MSG.createEnvironment("platform.xml")
+ MSG.deployApplication("deploy.xml")
+end
+MSG.run
+puts "Simulation time : " + MSG.getClock.to_s
+MSG.exit
+\endverbatim
- <i>MSG.createEnvironment(platform_file)</i> : set up the environment
- <i>MSG.deployApplication(deployment_file)</i> : load the deployment file description.
\subsubsection faq_binding_ruby_data Exchanging data
ruby bindings provides two ways to exchange data between ruby processes.
-\li MSG::Task.join & MSG::Task.data \br
+\li MSG::Task.join & MSG::Task.data <br/>
the MSG::Task class contains 2 methods that allows a data exchange between 2 process.
