One way to avoid deadlock is to schedule threads carefully. Assume the following characteristics of threads T1, T2, T3 and T4: • T1 (at some point) acquires and releases locks L1, L2 and L5 T2 (at some point) acquires and releases locks L2, L3 and L4 • T3 (at some point) acquires and releases locks L1, L2 and L4 T4 (at some point) acquires and releases locks L3, L4 and L5 For which schedules below is deadlock possible? . (a) T4, T2, T3, and T1 run concurrently. (b) T1 and T2 run concurrently to completion, then T3 runs to completion, then T4 runs. (c) T1 and T3 run concurrently to completion, then T2 and T4 run concurrently to completion. (d) T2 and T4 run concurrently to completion, then T1 runs to completion. O (e) T1 and T4 run concurrently to completion, T1 finishes first after which T4 continuous to run to completion with T2.

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…

Problem DescriptionThe Tower of Hanoi ProblemTower of Hanoi is a mathematical game consisting of three pegs (P1, P2 and P3) and a stack of disks of different diameters. Disks can slide onto any peg. The game starts with all disks stacked on P1 and ends at the point where all disks stacked on P3. The game player is required to move all disks from P1 to P3 using P2 as a buffer. Three rules must be followed when playing the game(1) Only one disk may be moved at a time.(2) Each move involves taking a disk on the top of a peg and place it on the top of another peg. (3) A disk of a larger diameter should never be placed on top of a disk of a smaller diameter. The diagrams below demonstrate the starting state and goal state of the game with 5 disks.Starting state Goal stateP1 P2 P3 P1 P2 P32RequirementsIn this assignment, students are required to solve the Tower of Hanoi (with five disks) using state space search algorithms implemented in Python.Two state space search algorithms: (1) a blind…

Part II: Processes and Threads. Write a C program that will creates a child process. The child will ask the user to enter an integers x and then sends it to the parent via pipe. The parent should print your student's ID if x > 0 or your full student name if x 0 and 01998877 if x <= 0. Note: cach student should print his own id and name as they appear on the UMS. The inter-processes communication should be using pipes.

3. I/O Management: Disk Arm Scheduling & RAIDa. It is known that a disk drive has 256 cylinders, with cylinder numbers starting from 0 and ending at 255. The position of the needle on the disk drive currently stops at 128. It is also known that the needle always “goes to the cylinder with the smaller number first”. The order of the positions visited sequentially is: 254, 64, 32, 100, 50, 70. From the 3 choices of algorithms below, which one is the best algorithm? Make each image and determine the seektime.i. SCANii. C-SCANiii. FIFO

Multi-tasking can not be achieved with a single processor machine.  True  False       2. Async/Await is best for network bound operations while multi-threading and parallel programming is best for CPU-bound operations.  True  False     3. The following is a characteristic of an async method:The name of an async method, by convention, ends with an "Async" suffix.  True  False   4. Using asynchronous code for network bound operations can speed up the time needed to contact the server and get the data back.  True  False     5. Asynchronous programming has been there for a long time but has tremendously been improved by the simplified approach of async programming in C# 5 through the introduction of:  The Task class  True  False
