I need to create a UNIX program for this assignment

In this assignment, you are to create an "archive" utility. It is a simple way to have some version control. You've created software projects before that change and grow over time. You might have several different copies of it (let's assume that it's all in one file). Perhaps before making major changes, you make a back-up copy, in case you later decide to revert to the earlier version. The idea is this: make a shell script program, called archive, that creates a back-up version of a file.

Notes:

  • This program should not be confused with the "tar" command.
  • The move command (mv) will preserve the time-stamp.
  • You will need to turn in a log file showing your program (i.e. with cat). Show that it works for several test cases.
  • You may be asked to meet to demonstrate your solutio

For this lab assignment you will need to write some code and create some graphs. You may use excel to create your graphs, or other language of your choice. Your data needs to demonstrate the experimental running time for Selection Sort (code in book), Merge Sort (code in book), and the Arrays.sort() method. Here is a basic outline of how you need to code this assignment. 1) Create several arrays of size 100, 1000, 10000, 100000, 1000000, … (you need...

Consider the C program (twoupdate) to demonstrate race condition. In this assignment, we will implement Peterson's algorithm to ensure mutual exclusion in the respective critical sections of the two processes, and thereby eliminate the race condition. In order to implement Peterson's Algorithm, the two processes should share a boolean array calledflagwith two components and an integer variable called turn, all initialized suitably. We will create and access these shared variables using UNIX system calls relating to shared memory – shmget,...

For this assignment you need to write a parallel program in C++ using OpenMP for vector addition. Assume A, B, C are three vectors of equal length. The program will add the corresponding elements of vectors A and B and will store the sum in the corresponding elements in vector C (in other words C[i] = A[i] + B[i]). Every thread should execute approximately equal number of loop iterations. The only OpenMP directive you are allowed to use is: #pragma...
