For project submission and automatic grading, we are running a dedicated server at https://sys.snu.ac.kr. If you want to access the sys server outside of the SNU campus, please send a request via a Google Form whose URL is posted in the eTL.
Currently, the CPU scheduler of xv6
uses a simple round-robin policy. The goal of this project is to understand the scheduling subsystem of xv6
by implementing the simplified version of FreeBSD’s ULE scheduler.
System calls are interfaces that allow user applications to request various services from the operating system kernel. This project aims to explore and understand how system calls are implemented in the xv6
operating system.
xv6
is an instructional operating system developed by MIT based on Ken Thompson and Dennis Ritchie’s Unix version 6 (v6). In this course, we will use xv6-riscv
, a version recently ported to a multi-core RISC-V machine. The goal of this project is to set up your development environment on Linux or macOS and familiarize yourself with our project submission server.
When | 12:30 - 13:45 (Tuesday / Thursday) |
Where | Lecture room #301-203, Engineering Building I |
Instructor | Jin-Soo Kim Professor, Dept. of Computer Science and Engineering, SNU |

Course Description | This course covers fundamental operating system concepts, such as process management, memory management, I/O systems, and file systems, with an in-depth study of the latest Linux operating system. In addition, students will engage in several hands-on projects using the xv6 instructional OS. |
