In this chapter, we learned how to configure the eight or sixteen nodes in your Pi supercomputer. We accomplished this task by initially editing the fstab file on the slave1 node to set up an automatic mount command, and then edit the hosts files on the master and slave nodes to reflect their temporary IP address. Next, we used the SD formatter for the Windows applications, to format the slave SD cards, and then the win32 Disk Imager application, to copy the slave1 image to the remaining formatted slave SD cards. We edited/updated the hosts file to reflect the actual IP addresses of the networked master and slaves, and edited the interfaces file on the super cluster nodes. Finally, we updated the MAC and IP address on the network switch for the remaining slave nodes. We will discuss testing the super cluster in Chapter 8, Testing the Super Cluster.
