- If two threads in a multithreaded program want the same resource at the same time, one of them will have to wait for the other to finish then which of the following can support this? Synchronized block Synchronized class Synchronized variable Process schedulingDescribe the mode switch between threads and processesSelect all that are true regarding variables and threading. A) atomic variables ensure operations on them are all or nothing B) volatile variables disable local caching of it C) atomic variables completely eliminate race conditions D) access to volatile variables are less efficient than synchronized variables
- The following question is related to Threading Task-1: Write a c program that creates 5 threads and prints which thread is running and after the thread is closed, a new thread starts its execution. Each thread should run sequentially one by one. OUTPUT: thread-1 running thread-1 closed thread-2 running thread-2 closedMulti-threading A) Write a Thread class (called worker) that takes two numbers (A and B, A < B) and calculates the products of all numbers between A and B. the result is stored in a local variable than can be accessed through a get method. B) Write a main program to calculate the factorial of a given number n (). The main thread reads n from the user, then creates two instances of Worker. Each one is requested to calculate the half of numbers between 1 and n. Once they finish, the main thread will gather their results and print the final result (result1 x result2). Example when n=10Multithreading: Select all of the following statements that are true. User threads must be mapped onto available kernel threads in order to be scheduled to be assigned to the CPU. A lightweight process (LWP) is a communication interface between different user threads of an application. The Many-to-One multithreading model allows the splitting of processes and threads across multiple CPUs. In the Many-to-Many multithreading model, a process always blocks whenever one of its threads blocks. A context switch between threads can be performed much faster than between processes. One advantage of multithreading is responsiveness, which means that one thread may respond instantly while other threads are blocked or busy doing calculations.
- THREAD -"C LANGUAGE" ONLY Write a program that uses 5 threads. Initialize a shared variable with a value of 0. Each thread must add its Thread ID (tid) to the shared variable. Once a thread has done the addition, print the ID of the thread. It is important to make use of mutexes so that only one thread is incrementing the shared variable at a time. Output the value of the shared variable once all threads have finished incrementing it.Lab 4 Directions Write a C program called threadcircuit to run on ocelot which will provide a multithreaded solution to the circuit-satisfiability problem which will compute for what combinations of input values will the circuit output the value 1. This is the sequential solution, which is also attached. You should create 6 threads and divide the 65,536 test cases among them. For example, if p=6, each thread would be responsible for roughly 65,536/6 number of iterations (if it's not divisible, some threads can end up with one more iteration than the others). The test cases must be allocated in a cyclic fashion one by one. #include <stdio.h>#include <sys/time.h>/* Return 1 if 'i'th bit of 'n' is 1; 0 otherwise */#define EXTRACT_BIT(n,i) ((n&(1<<i))?1:0)int check_circuit (int z) { int v[16]; /* Each element is a bit of z */ int i; for (i = 0; i < 16; i++) v[i] = EXTRACT_BIT(z,i); if ((v[0] || v[1]) && (!v[1] || !v[3]) && (v[2] || v[3])…Multi-threading A) Write a Thread class (called worker) that takes two numbers (A and B, A < B) and calculates the products of all numbers between A and B. the result is stored in a local variable than can be accessed through a get method. ). The main thread reads n from the user, then creates two instances of Worker. Each one is requested to calculate the half of numbers between 1 and n. Once they finish, the main thread will gather their results and print the final result (result1 x result2). Example when n=10
- The method area of a Java Virtual Machine (JVM) is a shared resource that is used by all of the threads that are currently running on the machine.Functions that are called by threads must have a property known as thread safety. T OR FSolve the following problem in C programming language: Four threads will run in parallel. The threads have a shared variable x. The initial value of x is equal to 0. The critical section of Thread1 and Thread3 will increment the value of x by 1, while the critical section ofThread2 and Thread4 will decrement the value of x by 2. The program will return the final value of x which will be equal to 2.
