I used the template scripts and it was ok but I have just seen that Cray 
Checkpoint is just for Cray Systems and CPR for SGI. It can not work 
with my Linux x86 computers ...

I think I have to use the Condor User-level checkpointing instead
or is there a kernel level checkpointing methode available for Red Hat 
distributions ?
