<h3> Automatic Deployment for ASP Environments </h3>
</center>
The objective of this thesis will be to find the solutions for Scheduling and Deployment adapted to an environment of grid computing.

 

<h4>Scheduling in heterogeneous medium</h4>  The very first problem with which we are confronted relates to applications scheduling.  It is significant to be able to find the computing power and the capacity storage necessary to a task; it remains with a given task.  Once identified the server able to solve the task, it remains to determine a scheduling that offers the greatest possible effectiveness.  The installation of such mechanisms in a heterogeneous medium of this scale initially requires lying out the information of two types: 
<br><br>
<li>the necessary resources can be obtained either by an approach based on algorithm modeling (if possible) or by a statistical approach based on a series of executions. 

<li> the available resources, for example with the installation of sensors giving a state of the system. 

 
<br><br>
The study and the setting open of these two approaches were initiated within project <a href="http://graal.ens-lyon.fr/DIET/">DIET </a>(Distributed Interactive Toolbox Engineering), but of much work remain to develop before validating these results. 

<br><br>
<h4>Deployment and scheduling in hierarchical medium</h4>  The concept of network hierarchical structure the Grid, implies strong constraints relating to extensibility of the platforms of grid computing.  A solution consists in considering a hierarchical approach of the executive support offering to the concept client-agent-server, an advanced structure multi-agents.  However, that introduces the significant problems of deployment.  In effect, the placement of the various agents becomes crucial in term of performance. 

 
<br><br>
It is then particularly interesting to be able to offer tools for deployment in adequacy with the scheduling can put at contribution.
