THREADS in C PROGRAM HELP! Using the thread3.c program provided below, itt will require some code modification. Those modifications include: - instead of 10,000 threads, create 40,000 threads in total - instead of creating just one kind of thread, create 4 kinds of threads (each with 10,000 instances) o group 1: adds 1 to counter o group 2: adds 5 to counter o group 3: subtracts 2 from counter o group 4: subtracts 10 from counter Run the program 5 times and take a screen shot showing the output of the run. Add comments throughout the code please! thread3.c given code: // Compile with://// clang -lpthread thread3.c -o thread3// or// gcc -lpthread thread3.c -o thread3//#include <stdio.h>#include <stdlib.h>#include <pthread.h> #define NTHREADS 10000 // shared variableint counter = 0; // thread to be executed - unspecified variable argumentsvoid *thread (void *vargp) {counter = counter +1;return NULL;} int main() {// array to keep Pthread IDs of created threadspthread_t…

1. Implement multithreading in Java Java allows a program to create threads during runtime by extending the Thread class or implementing the interface Runnable. Build a class to represent a thread. Each thread should be able to store and will be given a unique id so that your program will be able to track them (if you extends the class Thread, you may use the getName() and setName() methods from the Thread class). Build a Java program which creates 10 threads. Assign a unique id for each thread. You may use an integer as a counter and increase the counter every time a thread is created. A thread should print a message when it is created e.g. 'Thread 1 is created' (for thread with id 1).

15. 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   }

data comunication A program for communication between server and client will be developed. Multiclients (more than 1 client) can communicate with server simultaneously. While a client communication with the server, another clients should communicate with the server. The communication should be seen in consoles. TCP protocol will be used.. Thread functions should be used for the simultaneous communication

I have a web server program. It works as follows: the parent thread waits for new client connections. Once a new client connection comes in, the parent thread creates a child thread that services the client connection while the parent thread goes back and waits for more connections. Once the client connection finishes, the corresponding servicing child thread exits. When my code has undergone the usual code review process in my company, it has received major criticisms for being gravely inefficient. Name the optimization technique that I I have neglected to use? Clearly explain the technique and how the technique works and how it would improve the performance of my code.

Part 3: Interrupt handlingIn Java multithreading environment, one thread can send an interrupt to another by calling theinterrupt() method on the Thread object for the target thread (i.e., the thread to beinterrupted). To handle interrupts in a target thread, Java allows two approaches. One is performedby writing an exception handler for InterruptedException (only applicable if the targetthread is invoking methods which throw that exception such as sleep). The other approach isperformed by periodically checking the interrupt status flag Thread.interrupted andperforming the handling routine when that flag is set to true.Write a Java program that illustrates the use of the two approaches described above. Your programshould start by creating two threads, each thread should use different interrupt handling approach.Then, the program needs to send interrupts to each one of the created threads such that a threadneeds to return (i.e., stop execution) after receiving an interrupt from the main…

Write a Java program using Thread with single Server and Multiple Clients NOTE: Client must be running until Bye message is sent. Server should never stop

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.

1. Consider the track line in railways. If multiple trains trying to access the same line it should not allow because it will lead to collision. Now write a java program to schedule the track for the train. Create 3 threads objects for the class Train for 3 trains and schedule the Line by calling the getLine() (Synchronized method on the same Object but only one thread will be able to execute it at a time) in the Line class.

Create two Thread subclasses, one with a run() that starts up, captures the reference of the second Thread object and then calls wait(). The other class run() should call notifyAll() for the first thread after some number ofn seconds have passed, so the first thread can print a message

Problem 0. Write a version of hello.c that creates and reaps (joins) n threads, each of which prints "Hello, world" and its thread id, where n is a command-line argument, and the thread function is passed a pointer to its thread ID as its argument.

Socket programming The application consists of two parts: Server and Client. Each part can run independently on separate computers. Server manages the chat session. It maintains a list of the active clients and forwards incoming messages. The Server is multithreaded - communication with each client is through a separate thread. When Server is started, it starts to wait for client connections. This thread continues forever to listen for clients. When a connection request is received, the server starts a thread to service the client. This is necessary for each client to have its own socket. When the thread is started, a Client object is created containing all the relevant info about each client and saved in a list. The ServiceClient() thread is where all the work is done. ServiceClient() defines the implementation of the server side of the application protocol

1. Implement mutual exclusion with multithreading in Java Build a Java program which simulates a communication between a server and clients. You must use a thread to represent each party (as server or client). (Hint: study about the Semaphore class to perform mutual exclusion between threads) Create three threads. One thread will act as a server, which always ready to receive a message from a client (ping) and then replies the message to the same client (pong). The other two threads will become the clients, where each client will send a message to the server (ping) and waits for the reply (pong). Define 2 different classes to represent the server and the client. To perform the communication, each thread will refer to a same variable/data structure for sending and receiving the message. Use mutual exclusion approach to ensure each client can send and receive the reply without interruption from any other elient(s). For this simulation, your objective is to ensure that each client must…

Here, a solution that uses a single thread is preferable than one that uses several threads.

Modify the above thread program so that you implement the interface Runnable. Make themain thread waiting till all other threads finish execution.

In the four diagrams illustrated below, show which of them result in deadlock? For those situations that will result in deadlock, provide the cycle of resources and threads. For those situations which are not in deadlock, show by illustration the order in which the threads may complete their executions

In computer graphics when looking at synchronizations when building a renderer in engine development, what are moments where locks and unlocks from mutex's would not always work when looking at synchronization for a renderer in an engine?What I mean is when developing a game engine and you'll want there to be synchronization from a renderer thread and a main thread. Where renderer thread handles flushing and executing all of the concurrent tasks, whereas main thread would handle more of the querying tasks to a render command queue, and handling how these operations are operated within the engine.Can you give me some ideas on when mutex's may not be enough in a more complex? Where you may have multiple scenes, where animation physics are applied, and various vast ideas in this perspective?On another can you give me in great details what are uses of ref counters and different variations of implementations (in C++), and why reference counters are used? And what purpose do they have, as…

Consider a Semaphore named “mux”, Semaphore mux = new Semaphore(-2); mux.acquire(); number++; mux.release(); If three threads T1,T2 and T3 are trying to access the shared data (number) concurrently, a. Will any thread be able to go into its critical section? Explain. b. Will there be a race condition among the threads? c. What will be the final value of the variable “number” if its initial value is 0? d. Correct the code, if race condition exists.

Above is a python script that scans wifi networks. Please explain each line of code. Write an explanatory note about the libraries used and their methods.

In this particular situation, a solution that just makes use of a single thread is preferable than one that makes use of several threads.

Plz solve this question ASAP C language

In this particular situation, a solution with a single thread is preferable than a solution with several threads.

perform several operations at the same time. * Each Thread that you run works separately from the rest of the commands in the program, and therefore in the event of any error occurring in the Thread, it will not affect the rest of the commands in the program, as it does not affect any other Thread running in the program. In light of your study of multiple channels, • Write a program in the Java language that demonstrates this concept - you can choose the nature of the program that you want to achieve

Write a Java program using Thread with single Server and Multiple Clients. NOTE: Client must be running until Bye message is sent. Server should never stop. I need answer question pls

Kindly answer this as soon as possible. Urgent and answer all parts thanks. write a multi-threaded Java program that (i) Has a single Producer class object which is a thread and a single Consumer class which is also a thread. (ii) Create a class Packet. This class should contain a simple string. (ii) Create a class Buffer that internally uses some data structure to hold incoming packet objects – it should have methods insertPkt and removePkt and should have methods to tell the user how many packets are in the Buffer at any time e.g. size. (iv) Make the Producer object at random time intervals create Packet objects and place them in the Buffer object. (v) OBJECTIVE : Use a mechanism from the books Concurrency chapter to synchronize the producer thread pushing packets into the Buffer and the consumer thread removing them such that the Buffer size always remains between 50-70 packets. (vi) Show through any means how your objective is met by running the Producer and Consumer object.
