    The project entails developing a robust multithreaded Discrete Event Simulation (DES) engine using C and POSIX Threads. This engine is designed for detailed process-based simulations with a focus on advanced thread synchronization, including mutexes and semaphores. The second part involves simulating complex lock behavior scenarios to examine thread interactions and deadlock resolutions. The final deliverable includes integrating with the Perfetto tracing system to visualize and debug the simulation outcomes, providing a comprehensive tool for DES analysis. The project involves implementing a multi-threaded Discrete Event Simulation (DES) engine with a focus on process-based simulation. It's divided into two main parts: Completing a multithreaded simulation engine: You'l...

    Implement this idea in a fully functioning C++ program 8.17) In Section 8.5.4 of our textbook, we described a situation in which we prevent deadlock by ensuring that all locks are acquired in a certain order. However, we also point out that deadlock is possible in this situation if two threads simultaneously invoke the transaction() function. Fix the transaction () function to prevent deadlocks.

    Hi i have some work in cpp. Objective When dealing with threads and the need to access multiple mutex-protected resources, there is the possibility for “deadlock” to occur. Deadlock (sometimes called “deadly embrace”) is a situation where two or more competing actions are waiting for the other to finish, and thus neither ever does. To illustrate this, we are going to write code to run a drinking game. Objective You are given an incomplete codebase that will, when completed, play multiple games of Tic-Tac-Toe using multiple threads. Your objective is to control the flow of each game using condition variables. Don't worry about implementing the Log and LogSync functionality until you've already completed everything else.

    We have an application made with C# and Windows forms, we have some threads running at the same time to monitor and show some data, and also we have a barcode scanner connected via COM port. With the data that is coming from the scanner we perform some validations before save it to the DB. But some times the scanner is locked and the user is not able to use it until we restart the app. We assume that there is an error with the threads because the app is all the time opened and some threads are running in some kind scheduler every certain time. We need clarification on why the scanner stops to read and some way to prevent that behavior.

If deadlock occurs at any table, one of the philosophers drops any fork he/she is holding, and moves to a random unoccupied seat at the sixth table. Eventually, the sixth table will also have 5 philosophers seated at it, and therefore, it too will eventually enter a deadlocked state. In this problem, you are asked to simulate the above protocol using a thread for each philosopher and determine how long it takes for the sixth table to enter a state of deadlock.
