Processes And Threads Problem 1: Figure Below Contains Seven

Question

Processes And Threadsproblem 1figure Below Contains Seven States In Processes and Threads Problem 1: Figure below contains seven states. In principle, one could draw a transition between any two states, for a total of 42 dierent transitions (do you see why this is true?). Questions 1. List all of the possible transitions, e.g., all of the transitions that could be allowed and would be possible. Give an example of what could cause each transition. Questions 2. List all of the impossible transitions, e.g., all of the transitions that cannot occur. Explain why you believe each transition is impossible. ############################################################ Questions 1. What does this program accomplish? Please describe what happens with the global value myglobal. What does the thread_function() do and when does it run? What is the main() function doing? What is sleep() and what purpose does it serve? Question 2. Here is output from the above program being executed $ ./thread2 ..o.o.o.o.oo.o.o.o.o.o.o.o.o.o..o.o.o.oo myglobal equals 21 Is this the output you would expect? If not, what has gone wrong and how would you fix it (please show code)?

The problem presented explores the complex state transition possibilities in a system with seven distinct states, most likely representing various stages in process and thread management within an operating system. Understanding the full scope of potential and impossible transitions is fundamental for grasping how processes and threads interact, synchronize, and evolve within a multi-threaded environment. Part 1: Possible and Impossible State Transitions In a system with seven states, it is theoretically feasible to establish a transition between any pair of states, leading to a maximum of 42 potential transitions, given by the formula n(n-1), where n=7. This is because each state could potentially transition to every other state independently, barring any restrictions. For instance, a process in a "Ready" state might transition to a "Running" state upon scheduler dispatch, while a "Waiting" state might change after I/O completion. Allowed transitions include: From "New" to "Ready" upon creation completion. From "Ready" to "Running" when scheduled. From "Running" to "Waiting" if I/O or resource wait is needed. From "Waiting" to "Ready" once the wait condition is fulfilled. From "Running" to "Terminated" upon program completion or process kill. Transitions that involve state cleanup or resource release. Examples of what could cause each transition include: Process creation routines for "New" to "Ready". Dispatching algorithms for "Ready" to "Running". I/O interrupt completion for "Waiting" to "Ready". Process termination signals for "Running" to "Terminated". Part 2: Impossible Transitions Conversely, certain transitions are impossible based on the semantics of process states and the constraints of the operating system. For example: Transition directly from "New" to "Running" might be impossible because processes need to be placed in "Ready" before execution. A transition from "Terminated" back to "Running" without being recreated is invalid, since a process cannot r
