Ah, I thought it was an internal openMPI error number and 'grep'ed the source code without success. So "No rout to host" means that the TCP package could not be sent (usually host down, broken routing table, network interface down, ...). But it's 'ping'able and even rsh works fine. BTW, /etc/hosts.allow says "ALL : ALL", so there should be no trouble. Do I have to modify /etc/securetty in order to allow orterun to access the machines or is the rsh/rlogin entry sufficient? Thanks, Emanuel
