QUESTION 1 Which of the following is true about Concurrency Architecture?1.The concurrency architecture identifies the threads of execution, the allocation of software elements to those threads, specifies how the threads will be scheduled, and defines how resources will be shared among them.2.A platform (Operating System plus hardware) specialized for running multi-treaded applications3.Another term for multi-processing, system with more than one CPU4.Special hardware architecture needed to perform multi-threading
Describe the challenges and potential issues that can arise when multiple threads access shared resources concurrently, and how can these be mitigated.
Discuss the role of the operating system in managing dynamic multithreading. How does it allocate and manage threads dynamically?
Which concurrency mechanism would you suggest that might prevent the deadlock situation above? Rationalize answer. Do Execution Paths 3 and 4 encompass the first three conditions for a deadlock to occur? Explain your answer.
(Exercise 4.3) Which of the following components of program state are shared across threads in a multithreaded process? a. Register values b. Heap memory c. Global variables d. Stack memory (Exercise 4.4) Can a multithreaded solution using multiple user-level threads achieve better performance on a multiprocessor system than on a single processor system? Explain. (Exercise 4.6) Is it possible to have concurrency but not parallelism? Explain. (Exercise 4.9) A system with two dual-core processors has four processors available for scheduling. A CPU-intensive application is running on this system. All input is performed at program start-up, when a single file must be opened. Similarly, all output is performed just before the program terminates, when the program results must be written to a single file. Between startup and termination, the program is entirely CPU-bound. Your task is to improve the performance of this application by multithreading it. The application runs on a system that…
