The software  [http://dmtcp.sourceforge.net/ DMTCP] (Distributed Multithreaded CheckPointing) permits checkpointing of programs without having to recompile them. The initial execution is done with the program  <tt>dmtcp_launch</tt> and specifying the checkpoint intervals. The restart can then be carried out by running the script  <tt>dmtcp_restart_script.sh</tt>. By default, this script and the checkpoint files are written in the directory where the program was started. You can modify the location of these checkpoint files with the option  <tt>--ckptdir <checkpoint directory></tt>. You can run  <tt>dmtcp_launch --help</tt> to see all the options for DMTCP. Note that for the moment DMTCP does not work with software parallelized using MPI.

Message definition (Points de contrôle)
Le logiciel [http://dmtcp.sourceforge.net/ DMTCP] (Distributed Multithreaded CheckPointing) permet de faire des points de contrôles de programmes sans avoir à les recompiler.  La première exécution est effectuée avec le programme <tt>dmtcp_launch</tt> en spécifiant le temps entre les intervalles de sauvegarde. Le redémarrage se fait en exécutant le script <tt>dmtcp_restart_script.sh</tt>. Par défaut, ce script et les fichiers de redémarrage du programme sont écrits à l'endroit où le programme a été lancé. On peut changer l’emplacement des fichiers de sauvegarde  avec l’option <tt>--ckptdir <répertoire pour les sauvegardes></tt>. Vous pouvez faire <tt>dmtcp_launch --help</tt> pour obtenir toutes les options. Notez que DMTCP ne marche pas pour le moment avec les logiciels parallélisés par MPI.
