Description In this homework, you are asked to implement a multithreaded program that will allow us to measure the performance (i.e, CPU utilization, Throughput, Turnaround time, and Waiting time in Ready Queue) of the four basic CPU scheduling algorithms (namely, FIFO, SJE PR, and RR). Your program will be emulating/simulating the processes whose priority, sequence of CPU burst time(ms) and I'O burst time(ms) will be given in an input file. Assume that all scheduling algorithms except RR will be non-preemptive,...

JAVA Write a program that prompts the user to enter a file name, then opens the file in text mode and reads it. The input files are assumed to be in CSV format. The input files contain a list of integers on each line separated by commas. The program should read each line, sort the numbers and print the comma separated list of integers on the console. Each sorted list of integers from the same line should be printed together...

The picture is given in a PPM file and your program should put
the converted one into another PPM file.
•Use argv[1] for the given file and argv[2] for the converted
file.In addition, you can use a temporary file called
tmp.ppm.
•The number of rows and columns are not fixed numbers.
•The converted file should also follow the PPM format with the
above simplification, and can be converted subsequently.
•Read the pixel matrix into a buffer.

C++ Manually create a file Numbers.txtand fill it with integers, one below the other. Write a program that reads ANY sequence of integers (can be positive, 0 or negative) from this file. Using a looping construct, you will read numbers from the file till end of the file is reached. Calculate the largest and the smallest numbers among the data in the file. Your code must display both of those on the terminal screen along with total count of numbers...

QUESTION The ReadFile class opens and reads a text file. The WriteFile class opens and writes to a file. Compile and run these programs. There are several ways to read/write text files. The examples shown here are just one way of achieving this. Look at the API for the BufferedReader class. The readline() method is a simple way to read the text file line by line. It returns null when the end of the file has been reached. https://docs.oracle.com/javase/8/docs/api/java/io/BufferedReader.html Look...

Write a multi-threaded program with Semaphores as counters and pthread_mutex_t mutex to solve the producer-consumer problem: A bounded buffer is simply a global integer array of size N (2) which can be accessed by multiple threads. • Create two types of threads - Producer (2) and Consumer (2). Producers will write to the buffer, and the consumers will read the buffer. In this scenario,...
