##UW-Madison CS537 Section 3, Spring 2016

Project 1: Warm-up

http://pages.cs.wisc.edu/~remzi/Classes/537/Spring2016/Projects/p1.html

Part a: a simple sorting program to warm up with C
Part b: the goal of the project is simple: to add a system call to xv6. Your system call, getprocs() , simply returns how many processes exist in the system at the time of the call.

Project 2: Processes and Scheduling

http://pages.cs.wisc.edu/~remzi/Classes/537/Spring2016/Projects/p2.html

Part a: implement a simple command line interpreter (CLI) or, as it is more commonly known, a shell.
Part b: implement a new scheduler into xv6. It is called a simple priority-based scheduler.

Project 3: Memory Management

http://pages.cs.wisc.edu/~remzi/Classes/537/Spring2016/Projects/p3-section3.html

Write your own malloc() and free().

Project 4: Concurrency

http://pages.cs.wisc.edu/~remzi/Classes/537/Spring2016/Projects/p4.html

Part a: build a scalable web crawler.
Part b: add thread support into xv6. Implement the following system calls: int clone(void(fcn)(void), void arg, voidstack) int join(void **stack) and create a thread library.

Project 5: File System

http://pages.cs.wisc.edu/~remzi/Classes/537/Spring2016/Projects/p5.html

Part a: write a file system consistency checker(also known as fsck) for the xv6 file system.
Part b: change the existing xv6 file system to include high performance support for small files.
