: The Multithreaded Cook
In this lab, we'll practice multithreading. Using Semaphores for synchronization, implement a
multithreaded cook that performs the following recipe, with each task being contained in a single Thread:
1. Task 1: Cut onions.
a.
Waits for none.
b. Signals Task 4
2. Task 2: Mince meat.
a. Waits for none
b. Signals Task 4
3. Task 3: Slice aubergines.
a. Waits for none
b. Signals Task 6
4. Task 4: Make sauce.
a. Waits for Task 1, and 2
b. Signals Task 6
5. Task 5: Finished Bechamel.
a. Waits for none
b. Signals Task 7
6. Task 6: Layout the layers.
a.
Waits for Task 3, and 4
b. Signals Task 7
7. Task 7: Put Bechamel and Cheese.
a.
Waits for Task 5, and 6
b. Signals Task 9
8. Task 8: Turn on oven.
a.
Waits for none
b. Signals Task 9
9. Task 9: Cook.
a. Waits for Task 7, and 8
b.
Signals none
At the start of each task (once all Semaphores have been acquired), print out a string of the task you are
starting, sleep for 2-11 seconds, then print out a string saying that you…

- Programming Problems 9.28 Assume that a system has a 32-bit virtual address with a 4-KB page size. Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1.

You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…arrow_forward
