Subject: [OMPI users] remote host not accessible

Hi all,

I have installed Open-MPI on three machine which runs OpenSUSE and it
has been installed successfully. I can submit jobs locally on each
machine using "mpirun" and it works fine. I have defined a
host file on one of them (master) where I have defined IP address of
each machine and number of slots. First when I tried to submit jobs to
master it asked for password for SSH connection which showed
that master can communicate with slaves. Then I setup all machines to
communicate with each other using SSH without password. Now when I
submit a job on master, the job just blocks and nothing
happens. The program runs locally on each machine but it will not run
when I submit it on master to be run on slaves. What can it be?
