CS 110: Principles of Computer Systems Stanford University Winter 2022 CS 110 delves into advanced computer systems and program construction, focusing on designing large systems, software that spans multiple machines, and parallel computing. This course builds upon CS107 and requires good knowledge of C, C++, Unix, GDB, Valgrind, and Make. It covers Linux filesystems, multiprocessing, threading, networking, and more. CS107 took you behind the scenes:

- how things work inside C++/Python/Java, and how your programs map onto the components of computer systems
- understanding of program behavior and execution
 
CS110 uses this as a foundation to build complex programs that maximally take advantage of the hardware and operating system software available to us:

- How can we understand the designs and tradeoffs of large systems?
- How can we write software that spans multiple machines?
- How can we write software that runs tasks in parallel on a single machine? ### Course Topics Overview

1. **Overview of Linux Filesystems** - How can we design filesystems to store and manipulate files on disk?
1. **Multiprocessing and Exceptional Control Flow** - How can our program create and interact with other programs?
1. **Threading and Concurrency** - How can a single instance of our program perform multiple coordinated tasks at the same time?
1. **Networking and Distributed Computing** - How can we write programs that communicate over a network with other programs, and tackle large tasks using many machines?
1. **Additional Topics**: MapReduce, Caching, and Non-Blocking I/O **CS107 or equivalent -**

- Each of you should know C and C++ reasonably well so that you can...
    - write moderately complex programs (e.g. pointers, **malloc/realloc/free**, C strings, C++ classes, methods, references, templates, **new/delete**)
    - read and understand portions of large code bases
    - trace memory diagrams and always win!
- Each of you should be ﬂuent with **Unix, GDB, Valgrind**, and **Make** to the extent they're covered in CS107 or its equivalent.

The first assignment is meant to give you a sense of the scope of CS110 programs and refresh your memory on relevant prerequisites.  If you feel ok about it, you're all set! Second half of CS107 Textbook: *Computer Systems: A Programmer's Perspective by Bryant & O'Hallaron, 3rd Edition*

- Can purchase full copy, or Stanford Bookstore custom edition with just CS110 chapters

CS 110: Principles of Computer Systems Stanford University Summer 2021 Requiring familiarity with C/C++ and Unix/Linux, delves into computer systems principles. Students will engage with a blend of C and C++ to interface with system resources and manage complex projects. The course covers a broad range of topics including filesystems, multiprocessing, synchronization, networking, and MapReduce.   Formally, the prerequisite for the course is CS 107. Less formally, you need to be familiar with the C and C++ programming languages, Unix/Linux, `make`, Makefiles, `gcc`/`g++`, `valgrind`, `gdb`, and have some experience with basic computer architecture (x86 as it’s taught in CS107, or exposure to some other architecture with the confidence and ability to pick up x86 as I reference it). **If you have not taken CS 107, please email me at the beginning of the quarter to let me know.**

We’ll be coding in a mixture of C and C++ throughout the quarter. We rely on C, because the libraries needed to interface with system resources are written in C. We rely on C++, because the projects become large enough that I prefer to go with a more mature language that supports encapsulation and generic programming better than C does. You should understand pointers, dynamic memory allocation (`malloc`/`realloc`/`free`), and C strings perfectly. You should understand C++ classes, methods, references, templates, and C++'s `new`and `delete` operators. There are many C++ features you’re not expected to know, but you should have enough programming maturity to pick those features up and search the web for reference materials as needed.

The [CS 107 course website](https://web.stanford.edu/class/cs107/syllabus.html)is still up and may be a good reference. If you have not taken CS 107 and find yourself struggling, get help as soon as possible! This class moves quickly, and you will not want to fall behind. Email me and I may be able to point you to helpful resources. Readings are optional this quarter. I will post notes and slides with most lectures as reference material. However, if you would like additional readings to prepare for lecture or to reinforce concepts, I will list associated readings from the following textbooks:

- *Computer Systems: A Programmer’s Perspective* by Bryant and O’Hallaron, either the 2nd or 3rd edition. Both CS107 and CS110 teach from a subset of the B&amp;O textbook, the Stanford Bookstore carries a custom reader with just the chapters we need. Additionally, the Stanford library should have scans of this book available online in a week or two, although these are not yet available at time of writing.
- *Principles of Computer System Design: An Introduction* by Jerome H. Saltzer and M. Frans Kaashoek. The textbook should be available through the [Stanford library reserves](https://searchworks.stanford.edu/?f%5Bcourse%5D%5B%5D=CS-110-01) or [Science Direct](http://www.sciencedirect.com/science/book/9780123749574), and because it’s free, I assume most of you would just prefer to go with the free online version. Again, you’re welcome to purchase a hardcopy if you’d like. It’s available for purchase on [Amazon](http://www.amazon.com/Principles-Computer-System-Design-Introduction/dp/0123749573).

CSCI 0300: Fundamentals of Computer Systems Brown University Spring 2023 Introductory course covering computer system fundamentals including machine organization, systems programming in C/C++, operating systems concepts, isolation, security, virtualization, concurrency, and distributed systems. Projects involve implementing core OS functionality. CSCI 0300 covers fundamental concepts, principles, and abstractions that underlie the design and engineering of computer systems. You will learn how a computer works, how to write safe and performant systems software, and what systems abstractions support today's complex, high-performance systems developed in industry. Specific topics include machine organization, systems programming and performance, key concepts of operating systems, isolation, security, virtualization, concurrent programming, and the basics of distributed systems.

The course format is a combination of lectures, labs, and several hands-on projects involving programming exercises in C/C++. The goal of CSCI 0300/CS 300 is to teach the fundamentals behind the "magic" of computer systems from the hardware level to the global internet. We'll cover the ideas, principles and abstractions that unify computer systems design – from how your laptop runs multiple programs at the same time, to how companies like Instagram, Airbnb, and Google operate large websites, to how easy it is to exploit security vulnerabilities on badly designed systems. This is a great class for students who are interested in learning what systems programming is, how systems work, and why these systems are so critical to modern technology. This is an introductory computer systems course, designed to expose students to a broad set of fundamental concepts in computer systems and their practical applications. It is best suited for students who have completed the intro sequence, and to those who may want to deepen their understanding of systems concepts. Programming languages used in assignments include C and C++. ## CSCI 0300 highlights

- *Learn how a computer really works:* we'll look into what happens when a program runs, from the basics to high-level concepts!
- *Use industry-strength tools:* CSCI 0300 teaches you modern C/C++ programming with the tools that professional software engineers use!
- *Two programming languages for the price of one:* learn C and C++, two widely-used systems programming languages for high-performance software!
- *Real-world inspired projects:* in CSCI 0300's projects, you'll implement the core of your own operating system, and learn to build scalable infrastructure such as a distributed data store and a multi-threaded server similar to those companies use to run web services you use every day!
