Write a Java program that implements parallel programming using the Fork/Join framework. And must make use of the subclasses in the Fork/Join Framework. Step1- The program should initially generate 15 million random numbers. Step2-The generated numbers should be read into an array of doubles. Step 2- Then use a method that uses this array to calculate the sum of these doubles. Step 3-It must then display the sum and it must also output the number of processors available. Lastly, Have a clear screenshoot of code in the IDE and a screenshot of the code running.

Modify and run the program shown below in the following way. There is an array of 20 elements defined in the program. The elements of the array are: [20 18 16 14 12 10 8 6 4 2 -20 -18 -16 -14 -12 -10 -8 -6 -4 -2]. Thread 1 adds the first five elements [20, 18, 16, 14, 12], Thread 2 adds the next five elements [10, 8, 6, 4, 2], ..., Thread 4 adds the last five elements [-10 -8 -6 -4 -2]. Finally, the sum of all the 20 elements is printed by the main program. include <pthread.h> #include <stdio.h> #include <stdlib.h> #define NUM_THREADS 3 int counter=1; void *PrintHello(void *threadid) { counter = 2*counter+ (int) threadid; printf("\n Thread Id: %d Counter: %d\n", threadid, counter); pthread_exit(NULL); } int main(int argc, char *argv[]) { pthread_t threads[NUM_THREADS]; int rc, t; for(t=0;t<NUM_THREADS;t++){ printf("Creating thread %d\n", t); rc = pthread_create(&threads[t], NULL, PrintHello, (void *)t); if (rc){ printf("ERROR; return…

Exercise 1: Write a thread class TabPrinter that prints the elements of an array of integers (in one line) every 2 seconds 5 times. Use the way of extending the class thread. Write the main method which creates and starts three threads Printer which will print different arrays of integers. After that it prints "Main won’t wait. Main exits". Modify the above thread program so that you implement the interface Runnable. Make the main thread waiting till all other threads finish execution. ____________________________________________________________________________________________ Exercise 2: Write a thread class TextThread that prints a text every 1 second 10 times. Read the following main class. Try to guess what will be its output. class Test { public static void main(String s[]) throws Exception { TextThread x = new TextThread ("I am thread x"); TextThread y= new TextThread ("I am thread y"); System.out.println("I am Main thread"); } } Write it and execute it.

Could you kindly utilize solely my code as I contributed to its development? I emphasize, please utilize only my code.I attached my code below label my code. The question that I need help with: You need to use the pthread for matrix multiplication. Each threadfrom the threadpool should be responsible for computing only a partof the multiplication (partial product as shown in the above picture –all Ti(S) are called a partical product). Your main thread should splitthe matrices accordingly and create the partial data arrays that areneeded to compute each Ti. You must create a unique task with thedata and submit it to the job queue. You can compute the partialproducts concurrently as long as you have threads available in thethreadpool. You have to remove the task the from queue and submitto a thread in the threadpool. You should define the number ofthreads to be 5 and keep it dynamic so that we can test the samecode with a higher or lower number of threads as needed. When allthe…
Steps to be followed: Create a class called MyThread that extends the Thread class. Declare an instance variable int limitToStop in the MyThread class. Create a parameterized constructor in the MyThread class that takes an int as a parameter to initialize a limitToStop instance variable. Override the run() method in the MyThread class. In the run() method, put a for-loop that goes from 0 to limitToStop. The block associated with the for-loop should print out only the odd numbers. Call Thread.sleep(1000) after every number you print out in the for-loop you created in the previous step. The Thread.sleep(1000) method throws an InterruptedException , which is a checked exception. Therefore, we need to enclose the Thread.sleep(1000) call in a try block. Also, add a catch block associated with the try that catches the InterruptedException and prints out the exception information using the printStackTrace() method. Create a MyThread variable using the new keyword in the main()…

Parallel version 1 (Name this file as Q1_PLV1.java): o Repeat the sequential version using two threads along with the main thread. o Each thread creates a list of 25,000 students with randomly generated GPAs, randomly generated Ages, and sequential IDs. o Each of the two threads then calculates the average GPA and AGE (after creating the lists). o The two threads work in parallel. o The main thread waits for the two threads to finish and then calculates and prints the final average GPA and AGE from what is reported by the individual threads. • Parallel version 2 (Name this file as Q1_PLV2.java): o Repeat the Parallel version1 task using five threads (each is working on 10000 students) along with the main thread. To measure the time your computer takes to complete a certain task: • Read and store the current time (t1) before you start the task (e.g., before creating the lists), • After the task (e.g., after calculating the average), read and store the current time (t2). • The…
