Build Supercomputers with Raspberry Pi 3

Summary

In this chapter, we learned how to create a common user for all nodes. We achieved this by initially creating a new user for the master node, and then creating a password for that new user. We then employed a similar procedure for the slave1 node. Next, we generated a special key on the master node, copied the special key to the slave1 node, and then edited the .bashrc file on the master node to facilitate seamless special key access to all nodes in the super cluster. Finally, we used the which command to uncover the path to keychain. Chapter 6, Creating a Mountable Drive on the Master Node, discuss how to create a mountable drive on the master node. Go ahead and exit to the pi user pi@Mst0:~ $. If you are not now at the master node, close ...
