- Which of the following is NOT desirable in algorithms for parallel tasks? A Concurrency. B Non-determinism. C Synchronization. D Deadlock.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…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 pthread program to calculate the approximation of n. The method of calculating of the approximation was introduced in the class in the MPI part. You need to implement this method using pthreads. The number of threads and the number of terms required to calculate the approximation should be specified in the command line.Modify this threading example to use, exclusively, multiprocessing, instead of threading. import threadingimport time class BankAccount(): def __init__(self, name, balance): self.name = name self.balance = balance def __str__(self): return self.name # These accounts are our shared resourcesaccount1 = BankAccount("account1", 100)account2 = BankAccount("account2", 0) class BankTransferThread(threading.Thread): def __init__(self, sender, receiver, amount): threading.Thread.__init__(self) self.sender = sender self.receiver = receiver self.amount = amount def run(self): sender_initial_balance = self.sender.balance sender_initial_balance -= self.amount # Inserting delay to allow switch between threads time.sleep(0.001) self.sender.balance = sender_initial_balance receiver_initial_balance = self.receiver.balance receiver_initial_balance += self.amount # Inserting delay to allow switch between threads time.sleep(0.001)…Write a Java program using threads to compute the first 15 natural numbers, and to compute the first 50 Fibonacci numbers. Set the priority of thread that computes Fibonacci number to 9 and the other to 5. After calculating 30 Fibonacci numbers, make that thread to sleep and take up natural number computation. After computing the 15 natural numbers continue the Fibonacci number computing.
- In C++, not C please! Assume that your computer has 4 CPUs. Write a multithreaded program that runs 4 different threads concurrently. The entire process will add the first 1,000,000 numbers (from 1 to 1,000,000) to a shared variable sum. You need to use a pthread_mutex_t to provide mutual exclusion so that the final result of sum is 500,000,500,000 Note: you can download and modify the file summation_thread_shared_sum.cpp. This file does not use a mutex lock, so the result is incorrect. You must add a mutex lock correctly in the file so that the program generates the right outcome.Question#2: Write a Python program as follow: Contain a method named print time, that print current date and time Every 5 seconds create a new thread to invoke the print time method.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…
- Write a Java program that creates a new thread called PrintEven, that prints the Even numbers between 1 and N. N should be sent from the main thread to the PrintEven thread.in java fx Write a program that launches 1,000 threads. Each thread adds 1 to a variable sum that initially is 0. You need to pass sum by reference to each thread. In order to pass it by reference, define an Integer wrapper object to hold sum. Run the program with and without synchronization to see its effect.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…
