Answer #1

The algorithm that may face problems are - OPR and LRU
OPR -> Optimal Page Replace Algorithm
LRU -> Least Recently Used Algorithm
These algorithms may end up with different results for different users depending on the optimization used by the user.
The other to algorithm will always give same result because they are brute-force algorithms and can not change.

    Write a program that implements the FIFO, Optimal, MFU, and LRU page-replacement algorithms. Given a page-reference string, where page numbers range from 0 to 9, apply the page-reference string to each algorithm, and output the number of page faults incurred by each algorithm. Write your code so that the number of page frames in the page table can vary from 1 to 10. 1.0 Functional Requirements 1.1: Your program shall be run with the following: ./a.out Example: ./a.out datafile.txt 1.2:...

    This assignment requires you to create simulations for different scheduling algorithms commonly employed by operating systems to achieve multiprogramming. All problems in this assignment assume the following: The simulations you will be creating are for a uniprocessor system (single CPU). Processes in these simulations will require CPU bursts of one or more time units followed by I/O bursts of one or more time units. For simplicity’s sake, when more than one process is executing its I/O burst at the same...

    1 Overview The goal of this assignment is to help you understand caches better. You are required to write a cache simulator using the C programming language. The programs have to run on iLab machines. We are providing real program memory traces as input to your cache simulator. The format and structure of the memory traces are described below. We will not give you improperly formatted files. You can assume all your input files will be in proper format as...

    You might be familiar with Crazy Eddy, an owner of the “Crazy Eddy’s” home electronics stores that used to exist when you were younger (though maybe too young to remember). Some of the larger superstores like Best Buy and Circuit City moved in and began squeezing Eddy. As it turned out his tagline, “where the prices are insane,” was quite true, and he was forced out of business. Unbeknownst to many, Eddy was an avid skier, and his desire to...
