In Line 15 the program gets the number of threads it should start from the command line. Unlike MPI programs, Pthreads programs are typically compiled and run just like serial programs, and one relatively simple way to specify the number of threads that should be started is to use a command-line argument.

MPI, the Message-Passing Interface, is an application programmer interface (API) for programming parallel computers. It was first released in 1992 and transformed scientific parallel computing. Today, MPI is widely using on everything from laptops (where it makes it easy to develop and debug) to the world's largest and fastest computers.
