Description
Implement a CPU scheduler on top of Linux
using
threads and compare scheduling algorithms
Task :
1. Generate N concurrent threads. Each can be Producer and Consumer.
(Worker Threads)
2. Create the scheduler threads schedule the worker threads using Round Robin
method.
3. Create the Reporter thread for printing the change of status of different
worker threads.
Implementation :
1. Function used :
a. pthread_create : To create the thread
b. pthread_kill : To send the signal to specified thread
c. pthread_join : To wait for the thread to complete
d. signal() : For installing signal Handler
e. pthread_exit() : Exit from thread
2. Shared Memory : The variables are declared globally so that they can be
accessed by each thread.

How to Run :
$ g++ Ass4_3.cpp -lpthread -o thread
$./thread
