Chapter 6. Creating a Mountable Drive on the Master Node

This chapter discusses how to create a mountable drive on the master node. Effective, error-free operation of the Pi supercomputer requires that the slave nodes have the ability to mount the master node export drive/folder that contains the MPI code, so that each node will have their own identical code for carrying out a given task. In addition, you will be introduced to the powerful -H command, which can be employed to willfully task any or all threads, nodes, and cores to solve a given problem.

In this chapter, you will learn:

  • How to use the mkdir command to make an export drive (used as an MPI code repository) on the master node.
  • How to use the chown command to change ownership of the
