Each student will be able to:

• Given a loop-dominated C program, insert fork and shared memory commands to break the program into multiple processes during execution.
• Describe the similarities and differences between concurrency obtained through multiple processes and that generated by multiple threads.
• Consider a "broken" C program that attempts to use fork and shared memory commands to provide concurrency. Given the program code and a description of the (flawed) program behavior, identify what change(s) are necessary to make the program "work."
• Using words and/or diagrams, describe the difference in the amount of context state maintained by a process compared to a thread.
• Describe the similarities and differences among the following three different methods of interprocess communication.
  • Pipes
  • Shared memory among processes generated by fork.
  • Shared memory among threads generated by Posix thread commands.
