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:
