Step by step
Solved in 2 steps
- When your program starts, it shall do the following: Create a file, named QUOTE.txt, in the current directory (cwd). Have your running process write it’s pid (Process ID) followed by a Carriage Return and Newline into the file. Close the file QUOTE.txt Create a semaphore named FLAG which the threads will use to manage access to the file QUOTE.txt. Create 7 threads. Use the POSIX version of threads (i.e., pthread_create()) Block/wait for all seven threads to complete their work. Once all threads are done, destroy the semaphore, then exit gracefully, printing a friendly message to the console The Quote: Even numbered threads: “Controlling complexity is the essence of computer programming. --Brian Kernigan Odd numbered threads: “Computer science is no more about computers than astronomy is about telescopes.” --Edsger DijkstraWhich one of the following is not shared by threads? program counter stack both (a) and (b) none of the mentionedCreate 4 threads Assign them to run a function that generates 1000 random integers and write them to a shared file LOG.txt (THR#0: 123) In C please.
- Automatic variables are placed on the__, dynamically allocated variablesare placed in the___A. stack, filesystem B. filesystem, free store C. stack, free store D. free store, stackCreate a program that creates and runs 3 threads A, B, C and displays the string “Thread complete” after it has displayed the threads 50 times. It should display thread 50 times and displayed string "Thread complete". Use C language.340. A method used to temporarily release time for other threads. a. yield() b. set() c. release() d. start()
- Using C 1. Create a program that creates and runs 3 threads A, B, C and displays the string “Thread complete” after it has displayed the threads 50 timesAn application is to be coded using threads. Describe condition under which you would recommend use of (a) kernel-level threads (b) user-level threadsMINIX Programming - Please provide screenshots of what was changed so I can read it better and how to find the file Modify the MINIX 3 scheduler to keep track of how much CPU time each user process has had recently. When no task or server wants to run, pick the user process that has had the smallest share of CPU. DO NOT COPY AND PASTE SOME GENERAL ANSWER FROM SOMEWHERE ELSE
- Description You are provided a skeleton code in the file student_code.c. Some functions are completely implemented, and some are partially implemented. Additionally, you can add your own functions if required. Complete the program as per following details so that we can have functionality as described in the Synopsis above. All the code in single C file. REMEMBER DO NOT USE sleep(). 1. The given code reads the file's content for you and populates a dynamic array of type struct thread with information about the threads. The threads have filled in this list of threads for you. Additionally, you can check the threadCount variable to see how many threads were created using the input file. If more members are needed, you can add them. You might be able to initialise those extra members during file read if you wish to. 2. The main() already contains the code to read threads from input file. However, there is no code to initialize, execute and synchronize threads. You have to perform these…97. In high level programs, the command which sets the pointer of file to the beginning of that file is classified as a. modify command b. open command c. locate command d. reset commandIn 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.
