- This is some code in C for quicksort. The quicksort works correctly, but I am trying to implement multithreading. I am trying to run the recursive calls in parallel with a limit on how much threads can be running at one time (set by the global variable 'maximumThreads'). My logic is incorrect with managing how many threads can be ran at the same time. The part that I need you to look at is after the for loop in quick sort, where I have my logic for the mutex and the conditional variable. Right now when I run my code, the program runs without stopping. I would like help with correctly implementing this. #include <stdlib.h>#include <string.h>#include <pthread.h>#include <stdio.h>#define SORT_THRESHOLD 40typedef struct _sortParams {char** array;int left;int right;int* currentThreads;pthread_mutex_t* mutex;pthread_cond_t* cond_var} SortParams;static int maximumThreads; /* maximum # of threads to be used *//* This is an implementation of insert sort, which although…This is some code in C for quicksort.

- Computer Science 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 # threadsThere are few documents stuck for printing in a printing queue. The person responsible for printing performs certain random operations to get the documents running. For the above scenario which type of scheduling is suitable and why?In c++ if possible i have tried everything i can quite get it: Write a thread-safe logger implementation with interface: log(datetime timestamp, string severity, string message) that outputs lines to the console in the format: Timestamp [Severity] Message with the additional requirement that there must be a delay of at least 1 second before the line appears on the console. it must be: a. Exactly one line is printed to the console for each call to log. b. The call to log is non-blocking.
- Explain why synchronization is necessary in the following situation:You have modeled a bank as an array of BankAccountobjects. Each BankAccount object has an associated thread, which transfers money from this bank account to another, randomly selected bank account in the same bank. The amount to transfer is the same for all transactions. The threads work in parallel.Implement c# program to Retrieving a value using its associated key can be accomplished using an indexer, which works just like an indexer for an array. A key is passed in as the index value, and the value associated with the key is returned, unless the key doesn’t exist, in which a null is returned. you can use an indexer along with the Keys method to retrieve all the data stored in a hash tableCould you assist me with this code? I'm struggling to comprehend how to implement it. The code should be written in C and must involve a 5 x 5 matrix. I have the provide the question and my code. 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 partial…
- Design an isLocked() method that tests whether any thread is holding a lock (but does not acquire the lock). Give an implementation for any testAndSet (TAS) spin lock.What are the biggest benefits to creating a program or method that utilizes recursion in Java? In what scenario would it be appropriate to utilize a stack over a recursive implementation? Please provide an example to illustrate your points. In your answer, specifically think of and give a real-life scenario where: Recursion is used Recursion is preferable over iterationWrite a JAVA program that will maintain a phone directory using a Linked-List. The program should be able to perform the following operations: Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) Delete any person details by a given phone number. Update telephone number by providing person first name. Display all details of persons from a phone directory. Search telephone number based on person first name. (Note: use sequential search to find all telephones for the given first name) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory)
