CSCI 3150 Introduction to Operating Systems Project: Implementation of SFS Deadline: 23:59, Dec. 5, 2020 In this project, you are required to implement a simple file system called SFS. An overview of SFS is shown in the figure below. 1. SFS (Simple File System) SFS works on a file called HD that is a 110MB
Programming Languages Modules CSCI-GA.2110-003 Fall 2020 Modules Programs are built out of components called modules. Each module: ■ has a public interface that defines entities exported by the module ■ may include other (private) entities that are not exported ■ may depend on the entities defined in the interface of another module (weak external coupling)

[5pts] optimized for: Publish/subscribe systems like XFilter follow a model of supporting: The Google File System
The Google File System Sanjay Ghemawat, Howard Gobioff, and Shun-Tak Leung Google∗ ABSTRACT We have designed and implemented the Google File Sys- tem, a scalable distributed file system for large distributed data-intensive applications. It provides fault tolerance while running on inexpensive commodity hardware, and it delivers high aggregate performance to a large number of clients.
