Step by step
Solved in 3 steps
- 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.Wriite aa programm in c Main process should create a child process.Both parent and child processes will create one thread (e.g. parent process à thread A, child process à thread B). Compare the ids of parent and child, parent process and thread A, parent process and thread B, child process and thread A, child process and thread B. Display appropriate messages as per your comparison results. Parent process will take a number from user as input and will pass on this number to thread A while creating it. Before doing anything else, thread A will print the cube of that number.Course: Operating Systems write a multi-threadeddirectory copy program. The program will create destination directory and open thesource directory. Then for each file in the source directory it will create a thread. Thethread will copy file from source directory to the destination directory. At the end it willprint the number of files copied. Both the source and destination names will be passed ascommand line arguments. Sample execution is as follows:mtcopy.exe source_dir destination_dirCopied 8 files Note: The answer is availible on chegg.
- 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])…Write program for the following Create a child thread class for sorting an array of 10000 size string values Create a child class for calculating factorial of 50 Create a child thread class for calculating base b to the power p Create a single object of each thread in the main thread, and stop the execution of main thread until the termination of all child threads using join methodMulti-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 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 closedIn this particular situation, a solution that just makes use of a single thread is preferable than one that makes use of several threads.Solve 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.
- 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. 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=1015. It is also known that user credentials may be available in a remote database. The wanted user credentials need to be downloaded from a remote database. While the main thread executing the local processing, because an external database is accessed over the Internet, data accessing is executed in another thread. As the remote data is downloaded in a thread, the data needs to be passed back to the main thread. The following statement ensures that the main thread is updated on the main queue. DispatchQueue._______._______ { // do something here }10 Write a C program that creates five threads (in addition to the initial thread) and makes each execute a function task(void * i) for i integer ranging from 1 to 5. in this function, make an empty loop of 10000 steps, then display of the i number and the thread id on the screen. The initial thread will also perform the display. Check on this example that: — The use of the exit() function in one of the threads of the process leads to the termination of all the threads. — The termination of the initial thread leads to the release of all the resources, therefore the termination of all the threads of the process. How to avoid this premature termination?
