Write a program that simulates a toy paging system that uses the WSClock algorithm. The system is a toy in that we will assume there are no write references (not very realistic), and process termination and creation are ignored (eternal life). The inputs will be: The reclamation age threshhold The clock interrupt interval expressed as number of memory references A file containing the sequence of page references Describe the basic data structures and algorithms in your implementation. Show that your simulation behaves as expected for a simple (but nontrivial) input example. Plot the number of page faults and working set size per 1000 memory references. Explain what is needed to extend the program to handle a page reference stream that also includes writes.

Consider a system with the four access operations read, write, grant, and revoke. You can use grant not only to give other subjects read and write access, but also to grant them the right to grant access to the objects you own. Which data structure and algorithm would you use to implement the grant and revoke operation so that you can revoke all access to an object you own?
Implement a simulator for a process scheduling system using a heap. Jobs will be read from a file in this system that contains the job id, a six-character string, the length in seconds, and the priority of the job, an integer whose greater value indicates a higher priority. Each work will also receive an arrival number, which is an integer that indicates the order in which it arrived. The output of the simulation should include the job id, priority, duration, and completion time (relative to the simulation's start time of 0).
Modify the producer-consumer implementation code bellow, so that it uses monitors to handle race conditions instead of semaphores or mutexes. Use the pthread library implementation #include <pthread.h> #include <semaphore.h> #include <stdio.h> #include <stdlib.h> #define BUFFER_SIZE 20 pthread_mutex_t mutex; int count = 0; int buffer[BUFFER_SIZE]; pthread_t tid; int producers = 0, consumers = 0; void insert(int item) { while (count == BUFFER_SIZE); if (count < BUFFER_SIZE) { buffer[producers] = item; producers++; producers=producers%BUFFER_SIZE; sleep(1); } return; } int remove_item() { int item; while (count == 0); if (count > 0) { item = buffer[consumers]; buffer[consumers] = buffer[consumers - 1]; consumers++; consumers=consumers%BUFFER_SIZE; sleep(1); } return item; } void * producer(void *param) { int item; while (1) { item = rand() % BUFFER_SIZE; while (count >= BUFFER_SIZE);…
An “inverted file” is a critical data structure for implementing applications like the index of a book, or a web search engine. Given a document D (which can be viewed as an unordered, numbered list of words), an inverted file is an ordered list of words L such that for each word W in L, we store the indices of the places in D where W appears. Write a C# program (from scratch please, written by yourself (ask instructor if you are stuck), not borrowed from any other sources) that reads in a list of words separated by spaces from a text file, then uses an efficient O(N) algorithm to create the inverted file index (hint: consider the topic of this chapter, consider using a Dictionary/hashtable to help you), and writes this index out to another file or prints it to the screen. Each line of the output file should start with the next word (the words should be listed in alphabetical order, and this sorting does not have to be part of the O(N) runtime complexity, e.g. you can use regular…
A. Suppose that q1 is a class CircularQueue object that is using circular queue concept and the maximum size of the array implementing q1 is 10. The current index value of front is 5 while the current index value of rear is 9. i. What are the index values of front and rear after adding TWO (2) elements into q1? Draw the circular queue diagram to show the addition process. ii. After implementing the process in Question 2A (i), what are the index values of front and rear after removing FIVE (5) elements from q1? Draw the circular queue diagram to show the removing process. iii. What are the current number of elements after implementing the process in Question 2A (i) and Question 2A (ii)? =======================
Write a c++ program that reads in input commands related to a queue with no more than ten elements and performs the specified operations. Note that you should create three files, one for the main, one for Queue.h, and one for Queue.cpp. Those commands are: 'E', which will be followed by a number. You should enqueue that number 'D', which will dequeue the value from the front of the queue and print it, followed by a new line 'K'. which will peek at the value at the front of the queue and print it, followed by a new line 'Q', which will quit the program You can assume that all the input is valid.
you are to design a printer queue that is responsible for handling the printing requests coming from different users. You have to take into consideration that users have different levels of priorities. Each user has an identification number and a password, in addition to printing priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every printing request received, the program should check the priorities of that request and whether it can be moved forward in the queue to be served by the printer prior to serving the other requests. Using the programming language of your choice (preferably C++), write the printer queue that would handle the user request. The program must allow for requests coming from different users or from one user. Note: I need a working C++ code for this problem, and i need priorities.
Use a heap to implement a simulator for a process scheduling system. In this system, jobs will be read from a file consisting of the job id (a six-character string), the length of the job (an int representing seconds), and the priority of the job (an int where the higher the number the higher the priority). Each job will also be assigned an arrival number (an int representing the order of its arrival). The simulation should output the job id, the priority, the length of the job, and the completion time (relative to a simulation start time of 0).
Use C, C++, python or matlab to develop a program whose main routine accepts two parameters n and k, i.e. when you invoke your program from the shell, you pass it two parameters, n and k, where n >=16 and k >=3 and is in powers of 2 (e.g. 2, 4, 8, 16, etc.). Your main routine shall generate a random page trace of size n, where the page numbers have values ranging from 0 to ? − 1. Develop a subroutine within your program that implements the LRU page replacement algorithm (as a separate function within your program). Your algorithm shall use the doubly linked list stack implementation as outlined in slide 29 of lecture 10). The function shall accept a page trace and a parameter f for the number of frames allocated. Your main routine shall then apply the random page trace to the subroutine implementing the page replacement algorithm, multiple times (using only one trace, randomly generated), passing a parameter f (number of page frames used) that ranges from 4 to k. Your main…

The program should be able to perform the following operations: Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) Delete any person details by a given phone number. Update telephone number by providing person first name. Display all details of persons from a phone directory. Search telephone number based on person first name.
