implement the algorithm to calculate pi using mpi4py similar to The worker process finds the area under the function |01 (4/(1+x2) for its associated part as before. The number of processes is broadcast to all workers which can find their portions and then do the calculations using the function calc_pi. The root process then collects all results from the workers by adding them using the reduce operation and prints the result. Note that we can specify what to do with the collected data in reduce operation.
Read carefully this description before you answer this problem. We have 5 pages to be printed. We call the task of printing those five pages a Job, named J. Each of the subtasks is J1,J2,J3,J4,J5 that corresponds to the printing of an individual page, and thus J contains J1-J5. Start time is t=0 for all jobs. Job J completes when all jobs J1,J2, J3, J4,J5 get completed. Pages are printed one at a time. Preparing a single page to print takes 3s of instruction execution by the CPU. Printing it afterwards takes only printer time of 7s. If an interrupt handling mechanism is used, after the printer completes the printing of the relevant page 1s is spent for interrupt handling by the CPU. Interrupt handling has priority over other processor tasks and it is considered overhead. (1) What is the turnaround time in s for J when Blocked I/O (also known as Programmed I/O) is being used? (2) What is the turnaround time in s for J when interrupt-based I/O is being used?
For your initial post, identify a single algorithm that you use in your day to day life which involves repetition. As an example, washing each dish in a stack of dishes or a walk/don't walk sign switching from one mode to another after a set amount of time. Detail the steps of your algorithm in your post. As you detail the steps, make sure you break down each step fully. At a high level, explain how you would go about implementing the loop. Would you implement a while loop? A for loop? Would you make use of a "break statement?" Would your solution involve a nested loop?
Suppose we have a group of proposed talks with preset start and end times. Students of CSE340 were asked to design an algorithm to schedule as many of these talks as possible in a lecture hall, under the assumptions that once a talk starts, it continues until it ends, no two talks can proceed at the same time, and a talk can begin at the same time another one ends. Assume that talk j begins at time sj (where s stands for start) and ends at time ej (where e stands for end). One student proposed the algorithm shown in Algorithm 1 on the next page, which simply adds talks in order of earliest start time (smallest sj ). (a) Prove, using a counter example, that the proposed algorithm does not always produce an optimal schedule (i.e., a schedule with most possible talks). (b) Another student proposed adding talks in order of shortest duration (ej - sj ). Prove, using a counter example, that even with this new criteria, the algorithm does not always produce an optimal schedule.
Solve the following problems using Scala with Classic Akka Actors. For each problem, also implement client actors for sending the messages required for beginning the required computation. Use these client actors for testing your application actors. Recall the card shuffling problem. In a Faro shuffle, a stack of cards is broken up into two, and then combined so that a card from one sub-stack is followed by one from the other, and so on. A perfect Faro shuffle breaks up the stack into two sub-stacks of exactly the same size, and then combines them in the manner described above. An out-shuffle results in the top and the bottom cards of the stack remaining the same after the shuffle; an in-shuffle results in these cards becoming the second and the second last cards of the shuffled stack. Implement a shuffler actor which accepts a message containing a deck of cards as a list of even length, an integer indicating the number of times that the deck is to be shuffled, and a boolean…
A star configuration of a network represents its structure as a graph with an edge from a single, central node to each remaining node. A point-to-point configuration represents a network as a complete graph. Draw a picture of an example of each kind of configuration with four nodes, and use big-O notation to state the efficiency of adding or removing a given node in each type of configuration. You can assume for now that removing each edge is a constant-time operation. *Python
Consider a system of three independent, periodic real-time tasks: T1= (4, 3), T2 = (12,7), and T3 = (8, 5). Construct the schedule for these tasks in the interval [0, 24) with q=1 on twoprocessors with PF. Note that there are many PFair algorithms, while PF is one of them. PF prioritize subtasks by deadlines, and break ties by inspecting future subtask deadlines. Also, if a currently-executing job ties with a newly- released job, then continue executing the currently-executing job; break any other ties by task ID (T1 = highest, T3 = lowest). a. Show all sub jobs’ releases and deadlines for (the first job of) each task. Note that q=1 so each sub job should have execution requirement of 1b. Show the PF schedule.c. Will this task set be schedulable with q=2? Please explain.
Please help with implementing the Banker's algorithm for deadlock avoidance, that works on a given set of N processes and M resource types (N<10,M<10). Use Java for the implementation, with a simple text interface, where the user enters only the name of the input file (text only). The program reads all the necessary input data from that file. The input data and result is then displayed on the screen. Please help by using BACKTRACKING and find all solutions Subject: Java Programming
Exercise 2: We have two lists of the same length representing sensors data. The second sensor is supposed to be redundant, so that the two lists should have identical values. But for practical reason there are going to be small differences. In order to evaluate the quality of data collected with our sensors, we want to calculate the total absolute values of differences between the values. For instance: Sensor 1 reading: Sensor 2 reading: 15, -4, 56, 10, -23 14, -9, 56, 14, -23 1, Differences: 5, 0, 4, The total absolute differences is 1+5+0+4+0 = 10 Write a python program that takes two lists of values and computes the total absolute values of differences between the values
Find an assembly line scheduling using dynamic programming source codes (Java programming language) from Internet. Modify the codes to handle random generate of input for different number of stations. Add counters to count the primitive operations performed. Draw a graph that shows f(n) and n, where f(n) is the total number of primitive operations performed, n is the number of stations. Discuss the time complexity of the algorithm in term of best case, worst case and average case.
Make the shuffleSort programme. It first determines whether the data is accurate. If so, the sort is finished. If not, the process is repeated once the data is scrambled. What is the maximum runtime that is feasible? Is there a cap on how long it can run? What is your justification? If the data were randomly distributed and arranged in a never-before-seen way, would your response change?
Implement SRTF (SJF with preemption) scheduling algorithm in C programming. NOTE: Please do not print the average waiting time and the average turnaround time. You are required to compute these for each process and print the values for each process separately. Add comments in the code so that the code is understandable. Take input from the user: the number of processes, their CPU burst times and arrival times for n number of processes. Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming
