 /** \brief set a configuration variable
  * 
  * Currently existing configuation variable:
  *   - surf_workstation_model (string): Model of workstation to use.  
- *     Possible values (defaults to "CLM03"):
- *     - "CLM03": realistic TCP behavior + basic CPU model (see [CML03 at CCGrid03])
- *     - "KCCFLN05": simple network model (no latency) but interference 
- *       between computations and communications (UNSTABLE, DONT USE)
+ *     Possible values (defaults to "KCCFLN05"):
+ *     - "CLM03": realistic TCP behavior + basic CPU model (see [CML03 at CCGrid03]) + support for parallel tasks
+ *     - "KCCFLN05": realistic TCP behavior + basic CPU model (see [CML03 at CCGrid03]) + failure handling + interference between communications and computations if precised in the platform file.
  * 
  * Example:
- * MSG_config("surf_workstation_model","CLM03");
+ * MSG_config("surf_workstation_model","KCCFLN05");
