Thanks for your help.
It is finally working !!! The performance is increased more than 2.5X that
just using CPUs.
I was able to test up to 64 nodes (64 gpu, 256 cpus).
The idea of the aprun -cc none was the one that give me this great
I still do not understand the rank idea, I have been trying want you
but I am getting errors about the number of PP per node.
