This chapter discusses one node supercomputing. Initially, you will install the Linux (Ubuntu) OS on your PC (one node). Next, you will be instructed on how to access your PC processor's specs within the Windows environment. This information is critical for determining how many cores and/or threads (see Appendix) are available for Message Passing Interface (MPI) processing when using the -H command (this command is discussed in detail later in the book). You will then write and run a simple serial π equation code, and then write and run the MPI version of the serial π code. This coding exercise provides an initial feel for converting serial coding to MPI coding. The critical structure of the MPI π code's for statement is discussed, and finally, you will employ the MPI technique to generate π from the Euler, Leibniz, and Nilakantha infinite series expansions.

In this chapter, you will learn about the following topics:
