The goal of this assignment is to help you understand several basic UNIX$/$Linux primitives, imple$-$ mented at the process management layer of an OS$,$ such as fork$(),$ pipe$(),$ and execv$()$ as well as simple process synchronization and dataflow systems.

In this assignment, you will implement a program to synchronize, with Unix$/$Linux pipes, concurrent processes which perform arithmetic operations. You will learn concepts from several computer science disciplines, including data flow architecture, parallel computation, and, of course, operating systems. The input $($passed as the first argument of your main program$)$ to your program is a process precedence$/$dataflow graph specified in the following format:
