have you tested your ssh key setup, fire wall, and switch settings to ensure all nodes are talking to each other?

i can't run parallel program on more than one nodes
The nodes are cloned (so they are equals).
The mpiuser (and their ssh certificates) uses /home/mpiuser that is a nfs share.
I modified .bashrc
PATH=/usr/bin:$PATH ; export PATH ; LD_LIBRARY_PATH=/usr/lib64:$LD_LIBRARY_PATH ; export LD_LIBRARY_PATH ;
# already present below
if [[ $- != *i* ]] ; then
# Shell is non-interactive. Be done now!
The very very strange behaviour is that using the --debug-daemons let my program run succesfully.....
Thank you in advance and sorry for my bad english
