Reference in parrallel
In commit c7446750 the test case reference is based on a partition done by parmetis. Unfortunately this test case do not give always the same partitioning in between runs ... eXlibris_tools communication library which run in an asynchronous manner may induce different entities ordering in meshes. This may drive to graph with different node numbering and may impact parmetis in his graph partitioning. And maybe parmetis itself is not deterministic ?
This asynchronous specificity is also involved in other test case.
Reference in parallel should then be something more smarted then just results on partition that may differ from run to run ...
No solution for now .... but a solution must be found ...
