This first tutorial gives the OpenMOLE basics as well as examples to achieve your first basic workflow in console mode. Start!

We have added a new plugin in our repository. Its purpose is to give access to some sensitivy analysis methods available in the R platform. In this first version, we have integrated the fast99 method.

See the documentation of this plugin where you will find an example using fast99 method.

Actually, the plugin needs the R software to be launched on your computer in Rserve mode. We except to embed a prebuilt R distribution using recent virtualization task (see last blog entry).

Virtualization has been implemented within OpenMOLE.

For instance, in this MOLE, the task "hello" launches a VM and execute commands inside this VM:

import org.openmole.core.implementation.capsule.*
import org.openmole.plugin.task.groovy.*
import org.openmole.core.implementation.mole.*
import org.openmole.plugin.task.systemexec.*
import org.openmole.plugin.resource.virtual.*
import org.openmole.core.implementation.data.*
import org.openmole.core.implementation.transition.*
fileForVM = new Prototype("fileForVM", File)
file = new Prototype("file", File)
generateFileForVM = new GroovyTask("generateFileFor")
generateFileForVM.setCode("fileForVM = workspace.newTmpFile();\nfileForVM.write('Hello from groovy');\n")
generateFileForVM.addOutput(fileForVM)
virtualMachine = new VirtualMachineResource("/home/reuillon/Documents/Tmp/qemu/lucid_mini_comp.img","root","toor")
hello = new VirtualSystemExecTask("hello",virtualMachine,"hostname ; pwd ; echo `cat fileForVM` and also hello from vm >file")
hello.exportFileFromContextAs(fileForVM, "fileForVM")
hello.importFileInContext(file, "file")
disp = new GroovyTask("disp")
disp.setCode("println 'read from groovy: ' + file.text")
disp.addInput(file)
generateFileForVMC = new TaskCapsule(generateFileForVM)
helloC = new TaskCapsule(hello)
dispC = new TaskCapsule(disp)
new SingleTransition(generateFileForVMC, helloC)
new SingleTransition(helloC, dispC)
new Mole(generateFileForVMC).run()

The result of this MOLE is:

ubuntu
/root/fd394922-1e8d-441b-889b-8e052b8e43c0
read from groovy: Hello from groovy and also hello from vm

More testing has to be done.

For now OpenMOLE virtualization supports only GNU/Linux host. We need to compile qemu for Windows, MacOS, *BSD, Solaris and so on.

Next work will be to integrate legacy scientific software such as Scilab, Octave and R.
