Oups... sorry! I always forget the schema.xml. Correct me if I am
wrong: the mpiexec should always be launched we exactly the same
number of node specified in the schema.xml? That means if I put 20
nodes into that file I can't launch it with only 4?

Ok I go back to you if I don't find my problem.

Thanks for your help,

Sincerely,

PS:  Nothing to do with this topic, but when I launch the (C)VRP-TW
contribution until Linux Ubuntu 8.04.2 the timer has some problem:

Until Windows the timer works fine.
