- Can you help me with this code because i don't know what to do with this code, this code has to be in C. 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 partial products are computed all the threads in the…Write a Java program that asks the user to enter items until the user chooses to stop, stores them into links (nodes), and chains the links together into a linked list. You will need to make the following changes: Your linked list should store information about Customers' Transactions that contain three fields: customer name (string), customer number (int), and transaction description (string). Instead of putting all of your code inside the main source code file, you should create the following functions: o addToStart(Item x) o addToEnd(Itemn x) o insertAt(Item x, int n) o remove(int customer number) o reverse() o printList() • Instead of simply asking the user if they want to add a new link, your main program should offer the user a menu of options: o Add a new link to the end o Add a new link to the beginning o Insert an element at index n into the list. 0 Remove a link from the list o Reverse the list o print out the entire list o Quit the programWrite 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.

Step1- The program should initially generate 15 million random numbers. This should be read into an array of doubles. Step 2- Then it should make use of a method that uses this array to calculate the sum of these doubles. Step 3-This program should make use of the subclasses in the Fork/Join Framework. 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.Consider the BadReaderWriter.java program attached with this. The program has three threads, namely, one reader thread and two writer threads, and they all access the same list of numbers. The reader thread reads the list and prints it to the terminal. The writer threads append numbers to the list. At any point in time, if either of the writer threads finds that the list contains n elements, then it appends the number n + 1 to the list. Run this program, examine the output, and identify the problems.Fix these problems by implementing the acquireLock() and releaseLock() methods in the code.
- USE SIMPLE PYTHON CODE TO COMPLETE Basic version with two levels of threads (master and slaves) One master thread aggregates and sums the result of n slave-threads where each slavethread sums a different range of values in an array of 1000 random integers (please program to generate 1000 random integers to populate the array). The number of slave-threads is a parameter which the user can change. For example, if the user chooses 4 slave threads, each slave thread will sum 1000/4 = 250 numbers. If the user chooses 3 slave threads, the first two may each sum 333 numbers and the third slave threadsums the rest 334 numbers. 2) Advanced version with more than two levels of threadsThe master thread creates two slave-threads where each slave-thread is responsible to sum half segment of the array. Each slave thread will fork/spawn two new slave-threads where each new slave-threadsums half of the array segment received by its parent. Each slave thread will return the subtotal to its parent…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…Can you please help me with this code because I am struggling on how to do this, This has to be in C code. question that I need help with: Write a multithreaded program that calculates various statistical values for a list of numbers. This program will be passed a series of numbers on the command line and will then create three separate worker threads. One thread will determine the average of the numbers, the second will determine the maximum value, and the third will determine the minimum value. For example, suppose your program is passed the integers 90 81 78 95 79 72 85 The program will report The average value is 82 The minimum value is 72 The maximum value is 95 The variables representing the average, minimum, and maximum values will be stored globally. The worker threads will set these values, and the parent thread will output the values once the workers have exited. (We could obviously expand this program by creating additional threads that determine other statistical values,…
- Write a Java program that generates randomly a list of N integers, sorts the generated list using each of the three sorting algorithms: mergesort sort, quicksort that use the first element as a pivot, and quicksort that use the middle element as pivot and prints as output the execution time for each of the algorithms for randomly generate lists of size N = 40000, 100000 and 200000 and sorted lists as shown in the table.You are instructed to print the numbers from 1 to n in the venerable puzzle FizzBuzz. Print ", though, if the number is divisible by 3 instead "izz". Print it if it is divisible by 5 "Buzz". Print it if it is divisible by 3 and 5 "izzBuzz". You are required to carry out this task using multiple threads in this problem.Implement a four-threaded multithreaded FizzBuzz implementation. One thread prints and checks the divisibility of three "izz". A different thread is in charge of the divisibility of 5 and printing "Buzz". Divisibility of 3 and 5 is handled by a third thread, which also prints " "izzBuzz". The computation is done by a fourth thread.Arrays in Java are objects that use reference semantics. Explain what this means and How it affects modification of arrays. You must start a thread before you can read and reply to other threads
