- calculate the number of memory bytes accessed by this program: void my_dgemv(int n, double* A, double* x, double* y) { #pragma omp parallel { int nthreads = omp_get_num_threads(); int thread_id = omp_get_thread_num(); printf("Hello world: thread %d of %d checking in. \n", thread_id, nthreads); } // insert your dgemv code here. you may need to create additional parallel regions, // and you may want to comment out the above parallel code block that prints out // nthreads and thread_id so as to not taint your timings #pragma omp parallel for // insert your code here: implementation of basic matrix multiply for(int i = 0; i < n; i++) { #pragma omp parallel for for(int j = 0; j < n; j++) { y[i] += A[i * n + j] * x[j]; } } }Write complete Java code to define a thread for printing all the Odd Nos from 1 to 5000 which are divisible by 9. Thread must sleep for 5 seconds. Implement the threading using the Runnable java provided Interface. Finally, create three different threads with names ThreadOne, ThreadTwo and ThreadThree in main(). Execute the code in the file where threading is implemented. Apply the Java multithreading exception handling mechanism properlyPart 1: Thread creation (30%)a. Using Java multithreading library, write a Java program that calculates the sum of the numbersfrom 1 to 100,000,000. Split the numbers between four threads equally where each threadcalculates the sum of one fourth of the numbers. For example, the 1st thread will calculate the sumof the numbers from 1 to 25,000,000 whereas the 2nd thread will calculate the sum of the numbersfrom 25,000,001 to 50,000,000 and so forth. The main thread will have to print out the sum aftergathering the results. Note that you have the choice to create threads by either implementingRunnable interface or extending Thread class.b. Now, write a sequential version of the program described above using a single main thread (i.e.,without multithreading). Make sure to record and print out the time spent during the execution ofboth sequential and multithreaded versions (hint: you may consider usingSystem.currentTimeMillis() to record execution time).Part 2: Synchronization (40%)Assume…
- 7. Write an application in Java that creates and starts three threads. a. Each thread is instantiated from the same class.b. It executes a loop with 10 iterations.i. Each iteration displays the string "HELLO"ii. Sleeps for 300 milliseconds.c. The application waits for all the threads to complete & displays the message "Good Bye...".No screenshot needed, just explain the program and answer the red question to copy program /* Multi-threaded example */ #include <stdio.h> #include <stdlib.h> #include <pthread.h> #define NUM_THREADS 10 /*This data is shared by the thread(s) */ pthread_t tid[NUM_THREADS]; /*This is the thread function */ void *runner(void *param); int main(int argc, char *argv[]) { int i; pthread_attr_t attr; printf("I am the parent thread\n"); /* get the default attributes */ pthread_attr_init(&attr); /* set the scheduling algorithm to PROCESS(PCS) or SYSTEM(SCS) */ pthread_attr_setscope(&attr, PTHREAD_SCOPE_SYSTEM); /* set the scheduling policy - FIFO, RR, or OTHER */ pthread_attr_setschedpolicy(&attr, SCHED_OTHER); /* create the threads */ for (i = 0; i < NUM_THREADS; i++) pthread_create(&tid[i], &attr, runner, (void *) i); /* now join on each thread */ for (i = 0; i < NUM_THREADS; i++) pthread_join(tid[i], NULL); printf("I am the parent thread…Part 2: SynchronizationAssume that we have a file named “sharable.txt” which can be shared among several threads. Wewant to write a program that controls the access to that file in a way that only one thread at a timeis allowed to access it (i.e., for writing/appending purposes). Using Java multithreading, write aprogram that creates three threads and assigns a number to each thread. Then, each thread will startrunning by executing a code for opening the file “sharable.txt” and writing the following lines:Thread x started writingThread x is currently writingThread x finished writing – Student NameYour program should allow only one thread -at any given time-to access the file and write in it. Italso should keep away any thread from overwriting the lines written by any other threads (hint:use synchronized methods/blocks). Finally, when the execution of your program is completed, theoutput stored in “sharable.txt” should look like the following – put your name in place “YourName”:Thread x…

When a thread extends the Thread class, it must implement the sleep( ) methodSteps 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()…
- 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. Is the output convenient with your previous answer? What’s wrong? Complete the code so that all thread execute properly. Read the following second main class. Guess its output. class Test { public static void main(String s[]) throws Exception { TextThread x = new TextThread ("Hello"); TextThread y = new TextThread ("Java"); x.start(); x.join(); y.start(); System.out.println("I am Main thread"); } } Write it and execute it to check your previous answer.

Your task is to create two threads. One thread is adding random new numbers(1~100) into the list every 1 second. The second thread is removing all the odd numbers, and printing the list on the screen every 1.5 seconds. Your program should never end and please make sure to handle any race condition to avoid the ConcurrentModificationException.
