Chapter 8. Testing the Super Cluster
This chapter discusses how to test the super cluster (see definition in Appendix). Initially, you will shut down the entire supercomputer by sequentially using the shutdown -h now command at each node, and then reenergize the super cluster to reinitialize the machine as it progresses through its start up sequence. After the nodes are up-and-running, you will then engage multiple nodes using the -H command to run/test the super cluster by eviscerating the time need to solve the π function. Finally, you will create convenience bash files to facilitate ease of use of your supercomputer.
In this chapter, you will learn:
- How to use the
shutdown -h nowcommand to shut down your Pis - How to engage multiple cores/nodes, ...
