1. Solve synchronization problems inherent in inter-process communication and multi-threaded applications.
1. Process control system calls: The demonstration of fork, execve and wait system calls along with zombie and orphan states.
a. Implement the C program in which main program accepts the integers to be
sorted. Main program uses the fork system call to create a new process called a child process. Parent process sorts the integers using merge sort and waits for child process using wait system call to sort the integers using quick sort. Also demonstrate zombie and orphan states.
b. Implement the C program in which main program accepts an integer array. Main program uses the fork system call to create a new process called a child process.
Parent process sorts an integer array and passes the sorted array to child process through the command line arguments of execve system call. The child process uses execve system call to load new program that uses this sorted array for performing the binary search to search the particular item in the array.
2. Thread management using pthread library.
Implement matrix multiplication using multithreading. Application should have
pthread_create, pthread join, pthread_exit. In the program, every thread must return the value and must be collected in pthread join in the main function. Final sum of row-column multiplication must be done by main thread (main function).

Write a program in C using the fork() system call to do the following. The parent process (main program) forks a process (CHILD 1) to compute and print the sum of first n integers where n is a variable shared between the parent and CHILD 1. It also forks another process (CHILD 2) that finds the sum of squares of the first n numbers where n is a variable it shares with the parent. Let CHILD 1 print “The sum...

fibonacci sequence in C
The Fibonacci sequence is the series of numbers 0, 1, 1, 2, 3, 5, 8, .... Formally, it can be expressed as: f ib0 = 0 f ib1 = 1 f ibn = f ibn−1 + f ibn−2 i. Write a C program using the fork() system call that that generates the Fibonacci sequence by the child process. ii. If the user input as 5 then the child process has to output up to the 5 that is output must be 0,1,1,2,3,5. iii. Parent has to print the child process id and child has to print the parent process id. iv. Parent has to finish only after the child terminates. v. Is there any process synchronization problem here? Justify your answer. vi. Modify the above program to create a zombie process. How do y ou identify the zombie process? vii. Modify the above program to create an orphan process. viii. Compare and contrast the process and threads.

Sorting Threads Assignment Overview Write a multithreaded sorting program in Java which uses the merge sort algorithm. The basic steps of merge sort are: 1) divide a collection of items into two lists of equal size, 2) use merge sort to separately sort each of the two lists, and 3) combine the two sorted lists into one sorted list. Of course, if the collection of items is just asingle item then merge sort doesn’t need to perform the three steps,...

Please give a output Linux/Ubuntu and how to run it (compile) this program ,my assigment is below : : Merge Sort algorithm using 2 processes a.) Define an integer array of 100 integers. Populate this array with random numbers. You can use int rand(void); function. Do not forget to initialize this function. You will sort the numbers in the array using merge-sort algorithm. In merge sort algorithm the half of the array will be sorted by one process and second...

Assignment: Using the Fork System Call The Collatz conjecture concerns what happens when we take any positive integer n and apply the following algorthm: n={n / 2 , if n is even 3 * n + 1 , if n is odd The conjecture states that when this algorithm is continually applied, all positive integers will eventually reach 1. For example, if n = 35, the sequence is: 35, 106, 53, 160, 80, 40, 20, 10, 5, 16, 8, 4, 2,...
