IC2D is a graphical environment for remote monitoring and steering of distributed and grid applications. IC2D features graphical visualisation and drag and drop migration of remote objects. As it is being interfaced with Jini and Globus, it can also serve as a building block for grid and computing portals. IC2D is built on top of RMI and ProActive that provides asynchronous calls and migration.
The basic features of IC2D are:
Graphical Visualisation | Textual Visualisation | Control and Monitoring |
Hosts, Java Virtual Machines, Active Objects | Ordered list of messages | Interactive control of mapping upon creation |
Topology: reference and communications | Status: waiting for a request or for a data | Interactive control of destination upon migration |
Status of active objects (executing, waiting, etc.) | Causal dependencies between messages | Dynamic change of deployment |
Migration of activities | Related events (corresponding send and receive, etc.) | Drag and Drop migration of executing tasks |
The full source of IC2D is included in the distribution and is also browseable
on line.

IC2D features graphical visualisation of hosts, Java Virtual Machines, and active objects, including the topology and volume of communications.
A 'drag-and-drop' migration allows to graphically move running active objects between machines.
The launcher allows users to launch applications directly from an XML
descriptor file, without any script. The new XML descriptor is nearly the
same as classical descriptor files, the syntax is only extended.
The deployment will be done in two different phasis.
first, a new node, a "main node" will be created and activated and then,
it is this node that will deploy the rest of the application.
A new tag has been introduced, just before the component definition tag.
This tag is named "mainDefinition" and its syntax is :

The Launcher class is located in the package org.objectweb.proactive.core.descriptor.
To use it you will have to create a new instance of the launcher with the path of
the XML descriptor (this descriptor must contain a mainDefinition tag).
The constructor will parse the file and reify a ProActiveDescriptor.
You only have to call the activate() method on the launcher instance to launch
the application.
For example:
Launcher launcher = new Launcher ("myDescriptor.xml") ;
launcher.activate() ;
you can also get the ProActiveDescriptor built by the launcher by calling the
getDescriptor() method on the launcher instance.
ProActiveDescriptor pad = launcher.getDescriptor() ;
You will find the launcher in the launcher menu, in the menu bar. Click then on
launch a new application.
Now it opens a new window proposing you to browse your file system for a XML descriptor and load it into a descriptors list. A right click on the list items allows you to launch (activate) the application. Two checkbox control the graphical monitoring and textual job monitoring your application.
You can kill the applications launched with from a popupmenu in the "activated applications" table.
As ProActive is interfaced with Globus and LSF, IC2D permits to interactively control and debug applications that execute on intercontinental-wide networks. Below is C3D application deployed with JINI and RMI protocol between Baltimore US and Nice France on a globus cluster and LSF cluster
