- <<Java Programming>> Question: Your job is to write a java program where 3 people (X, Y, Z) will communicate with each other. It's a conversation between these 3 people! You have to use multi-threading and they will continue their conversation till 1 person/1 Thread says "BYE"! When 1 person says bye it will print "X/Y/Z is no longer available in this chat" [I'm a beginner it will be great if you add more and more comments!! Please use basic java methods, not pro-level! It will be more than great if you add a flow chart of your process]Const N = 50; Var Tally: integer; Procedure Total; Var Count:integer; Begin For Count := 1 to N do Tally := Tally + 1 End; End; Begin (* main program *) Tally := 0; Parabegin Total; Total; Paraend; Write (Tally) End. Compose a thread safe pseudocode version that guarantees the upper and lower bound of the shared variable Tally are the same value after execution.In C++ This exercise involves implementing the solution to the bounded buffer/readers and writers problem using threads. You will create a program that accepts four command line arguments: run_time (the length of time the program should run) buffer_size (number of slots in the bounded buffer) num_producers (number of producer threads) num_consumers (number of consumer threads) The program will create a thread for each producer and consumer. As each thread produces or consumes a data item, it will print its status. Example Output Here are some sample runs: Not enough arguments If not enough arguments are provided, the program should print an error message and exit. $ ./bounded_buffer Wrong number of arguments. Usage: bounded_buffer <run_time> <buffer_size> <num_producers> <num_consumers> $ Invalid argument If an argument is less than or equal to 0, the program should print a message and exit $ ./bounded_buffer 10 5 1 0 ./bounded_buffer 10 5 1 0 num_consumers…
- An application loads 100 libraries at start-up. Loading each library requires exactly one disk access. The seek time of the disk to a random location is given as 10 ms. Rotational speed of disk is 6000 rpm. If all 100 libraries are loaded from random locations on the disk, how long does it take to load all libraries? (The time to transfer data from the disk block once the head has been positioned at the start of the block may be neglected.)You'll write a C++ program to demonstrate thread synchronization. Your main function should first create an empty file called *sync.txt*. Then it will create two separate threads: *Thread-A* and *Thread-B*. Both threads will open *sync.txt* and write to it simultaneously. *Thread-A* will write the numbers 0 through 9, a total of fifty-thousand times in nested `for` loops, then exit. In other words, print the numbers 0 through 9 over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line: ```text 0 1 2 3 4 5 6 7 8 9 ``` Somewhat similarly, *Thread-B* will write the letters A through Z fifty-thousand times in nested `for` loops, then exit. In other words, print the letters A through Z over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line: ```text A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ``` Do not write each line as one long string. You must write each character to the…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,…
- The following question is related to Threading in C programming Task-3: Write a program in c that has a function that takes the name of the user and adds all the ASCII value of the characters and returns it. Now create 3 threads that run the function using 3 different user names. Now print “Youreka” if all the returned values are equal, print “Miracle” if the 2 returned values are equal, and print “Hasta la vista” if the values don’t match using another thread.The Fibonacci sequence is the series of numbers 0, 1, 1, 2, 3, 5, 8, .... Formally, it can be expressed as: fib0 = 0 fib1 = 1 fibn = fibn−1 + fibn−2 Write a multithreaded program that generates the Fibonacci series using either the Java, Pthreads, or Win32 thread library. This program should work as follows: The user will enter on the command line the number of Fibonacci numbers that the program is to generate. The program will then create a separate thread that will generate the Fibonacci numbers, placing the sequence in data that is shared by the threads (an array is probably the most convenient data structure).When the thread finishes execution, the parent thread will output the sequence generated by the child thread. Because the parent thread cannot begin outputting the Fibonacci sequence until the child thread finishes, this will require having the parent thread wait for the child thread to finish.Write a C++ code with threads: Compute π by “randomly” choosing points. π is four times the fraction that falls in the circle (imagine you’re throwing darts to a target). Ac = π r 2 As = 2r*2r = 4r2 P = Ac/As = π/4 • You should use a thread-safe real uniform random generator • Make a table for different values of n (# darts) and # threads
- 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…Parallel:- Implement the parallel utility that has 3 command line arguments. This will execute 4 copies of the sleep process for 10 seconds. Your program should allow an arbitrary number of command line arguments for the process to be run in parallel. The parent process should wait for all child processes to finish before exiting back to the shell. If the format of the command is not recognized (e.g. the first argument is not an integer), an error can be displayed. All your code should be contained in the parallel.c file, and the Makefile. ./parallel<processes><cmd><args> For example, if you type: ./parallel 4 sleep 10 OUTPUT: SUCCESS in running 4 parallel sleep tasksImplement a solution to the critical section problem with threads using semaphores. you must add a third counting thread which counts by 1 each time it enters its critical section to 3,000,000. Each counts to 3,000,000 for a total of 9,000,000.
