In Class Assignment/Quiz:

Instructions: Develop a pseudocode solution to the following problem. Email to Tom.Halverson@dsu.edu  when complete.

Problem:

• Assume we have 3 processes
• We wish to allow the processes to operate in round robin format. That is, process A does its work, then process B, and then process C.  They continue in this manner indefinitely. 
• We do NOT know
  • Process names
  • Process ID numbers
  • Basically, you can't use if-statements to check if you can work
• You should instead assume that each process has a separate code segment
  • process P()
    repeat until done
          work
• Use only semaphores as the synchronization method.
• Show a "declaration" of the semaphore(s)
• Show the initialization of the semaphore(s)
• Show the basic code structure for each process. Add to the outline above to show how the synchronization fits in to this structure.
  • inside the "repeat until done" loop
