Multi-cpu computation HPMPI problem

I have installed recently starcd on a new computer, and I am facing with a problem when trying to ran a computation on several CPU.
I am able to run Starcd on 1CPU, without problem.
I can also run several single-CPU computation at the same time.
However, when trying to run the computation on 2 or more CPU, I am getting the following error message:
mpirun: gethostbyname(crevoise) failed
mpirun: Cannot find IP for mpirun matching crevoise
It seems HPMPI is trying to access different IP address for each CPU?
Does somebody already faced with that problem and have some hint to solve it?
