+== Issue description ==
+
+ * We found that if we run mpd with superuser privilege (i.e. root permission), normal user in each node can not connect to mpd to run R-MPI.
+   * First, we had finished the ip and hostname mapping by modifying /etc/hosts, and then use scp to exchange ssh public key to each compute node.
