 = How to run R-MPI on multiple machine with normal user permission =
 
-== 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.
