A Pregel worker: a) Contacts the master for a set of vertices that have not yet been processed in a given superstep and calls the Compute() method on each vertex. b) Is responsible for a single vertex of a graph, calling the Compute() method on that vertex if it is active. c) Is allocated a single partition and runs a thread for each vertex of a graph that loops calling a Compute() method as long as the vertex is active. d) Runs a thread for each partition of a graph, with each thread calling a Compute() method as it iterates through each active vertex.

Implement a Multithreaded Sudoku Solution Validator using POSIX thread library in C Specifications This assignment consists of designing a multithreaded application that determines whether the solution to a Sudoku puzzle is valid. A Sudoku puzzle uses a 9×9 grid in which each column and row, as well as each of the nine 3×3 subgrids, must contain all of the digits 1 to 9. Following figure presents an example of a valid Sudoku puzzle solution. There are several different ways of multithreading this application. In this assignment, you need to implement the strategy to create multiple worker threads that check the following criteria: Nine threads to check that each of the 9 columns contains the digits 1 through 9 Nine threads to check that each of the 9 rows contains the digits 1 through 9 Nine threads to check that each of the 3×3 subgrids contains the digits 1 through 9 This would result in a total of 27 separate worker threads for validating a Sudoku puzzle solution.The parent…
Round-Robin (RR): Write a Java program to implement a Round-Robin (RR) scheduling algorithm with quantum q that will be entered by user. Your program should first prompts the user to input a list of process ID, arrival time, and burst time (in ms) for each process to be run on the CPU. The list is terminated by 0 0 0 for the process ID, arrival time, and burst time. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the RR scheduling algorithm. Also print the turnaround, response, and waiting time for each process along with their average for all processes. Make sure to display very helpful messages to the user for input and output.
For the following piece of code, 1) Please plot the control flow graph assuming per basic block per vertex. 2) Please plot the control flow graph assuming per statement per vertex. 1 a := 0 b := a * b L1: c : b/d if c 0 goto L3 7 8 L2: g := f h := t - g if e > 0 goto L1 10 11 goto L1 12 L3: return a 2: 23 4+ 6
PLEASE USE PTHREADS Write a program in C using PTHREADSthat will simulate the operations of the following Batch scheduling algorithms: PLease use Pthreads First-Come, First-Served Shortest Job First Your Program will implement threads for each algorithm plus the main thread. A linked list will be used to represent the list of jobs available to run. Each node will represent a Job with the following information: int PID Process ID int time; The time needed on CPU to finish executing Main thread: Your main code will request the user to input a list of jobs, and to fill the information in each job node until a sentinel value is reached, each data item will be stored in a separate node. Starts the FCFS thread, followed by SJF thread. Wait for both threads to finish before exiting. FCFS thread: The thread will simulate the First-Come, First-Served algorithm. Displays the data in a list in the order they were inserted. SJF thread: The thread will simulate the Shortest…
When an interrupt occurs, the CPU stops what it is doing and returns to its previous task of servicing the next process in the queue. Is it necessary to postpone the execution of the sentence? Instead, how about you just carry out the surgery and leave the rest to us to deal with it?
Define the term " overflow queue " .
Define the term " queue rear " .
Use the PERT diagram shown to the right to answer the following questions. Assume that time is measured in days.a. Find a critical path for task G.b. Find a critical path for task H.c. Find a critical path for the vertex "End."d. On what day will task F begin?e. On what day will task G begin?f. How many days are required to complete this project?
Some applications require two types of accesses to the critical section-read access and write access. For these applications, it is reasonable for multiple read accesses to happen concurrently. However, a write access cannot happen concurrently with either a read access or a write access. Example: For a sequence [R1, R2, W1, R3] of requests, R1 and R2 should be able to access the critical section concurrently while W1 and R3 wait in the queue. Once R1 and R2 leave the critical section, W1 can enter the critical section while R3 waits in the queue. (a) Modify Lamport's algorithm for such applications. (b) Modify Ricart and Agrawala's algorithm for such applications.
Consider the linked list in the image. A node in the linked list is defined as follows: node begin data: element of any datatype link: pointer to node end f is a pointer to the first node in the linked list If q is a pointer then, q.link contains q's link q.data contains q's data Find the output of the print instruction based on the following operations: p=f.link.link p.link.link=p print (f.link.link.link.link.link.link.data) The instructions are not dependent on any programming language. Write your answer in the box given below. Use the same case for the characters as given in the question. Do not insert any spaces in the answer.
A linked queue is a single linked list in which: (A The last node of the linked list is both the front of the queue and the rear of the queue. The first node of the linked list is the rear of the queue and the last node of the linked list is the (в front of the queue. The first node of the linked list is both the front of the queue and the rear of the queue. The first node of the linked list is the front of the queue and the last node of the linked list is the rear of the queue.
It is known that when an information system processes data, a Linked Stack is used, and the name of the indicator pointing to the top of the stack is Top. When the input data enters the system, it needs to be stored in the stack first, and then the information system will extract the data from the stack to perform operations as required. it is known that the sequence of a set of integer data entering the aforementioned information system is as follows; 27, 98, 24, 9, 83 In the initial stage of the aforementioned information system, the Stack is in an empty state, and in the process of entering the above-mentioned integer data string into the information system, the operation sequence of the Stack is as follows; Push, Push, Pop, Push, Push, Push, Pop Please diagrammatically depict the Linked Stack of the information system at each stage of operation
