4.1. It was pointed out that two advantages of using multiple threads within a process are that (1) less work is involved in creating a new thread within an existing process than in creating a new process, and (2) communication among threads within the same process is simplified. Is it also the case that a mode switch between two threads within the same process involves less work than a mode switch between two threads in different processes?

Define coarse-grained multithreading and fine-grained multithreading. Explain a scenario in which one multithreading would be preferred over the other for better performance in thread switching.

Explain the concept of thread synchronization and discuss different synchronization mechanisms, such as mutexes, semaphores, and barriers, highlighting their use cases.

Some issues need to be considered in designing multi-threaded system. One of these issues involves Thread Cancellation. Discuss the two types of target-thread cancellation, support your answer with examples.

Your theory on why the method area of a JVM is shared by all threads operating within the virtual machine raises an interesting question.

Write an ALP program for ARM Cortex M3/4 to perform the following(1) SVC is to be called from an application task running at Thread unprivileged mode.(2) Two parameters are passed to the handler via R1, R2.(3) If the SVC number is last 3 digits of your Student ID (0 to 255) or last 2 digits of your Student ID (if last 3-digits of Student ID > 255), then the addition of the data in R1, R2 should be performed and after that return and resume application task.(4) If the SVC number is not your Student ID (3 or 2 digits), then return and resume application task.Give suitable screen shots of the KEIL IDE-in debug mode to demonstrate the desired outputs.

Explore the different threading models, such as user-level threads and kernel-level threads. What are the advantages and disadvantages of each?

Consider the following three CPU organizations:CPU SS: A 2-core superscalar microprocessor that provides out-of-order issue capabilities on 2 function units (FUs). Only a single thread can run on each core at a time.CPU MT: A fi ne-grained multithreaded processor that allows instructions from 2 threads to be run concurrently (i.e., there are two functional units), though only instructions from a single thread can be issued on any cycle. CPU SMT: An SMT processor that allows instructions from 2 threads to be run concurrently (i.e., there are two functional units), and instructions from either or both threads can be issued to run on any cycle. Assume we have two threads X and Y to run on these CPUs that include the following operations: Thread X Thread Y A1 – takes 3 cycles to executeA2 – no dependences A3 – conflicts for a functional unit with A1A4 – depends on the result of A3 B1 – take 2 cycles to executeB2 – confl icts for a functional unit with B1B3 – depends on the result of…
