Prerequisites

Students are expected to have a solid grasp of simple data structures (such as lists and arrays) and some programming experience. (CSE 116 or equivalent experience.)

Text

There are two texts for this course:

  • Computer Systems: A Programmer’s Perspective, Third Edition, by Randal Bryant and David O’Hallaron.

  • The C Programming Lanuage, Second Edition, by Brian W. Kernighan and Dennis M. Ritchie.

Both of these books are truly excellent, and I recommend that you consider buying a copy to keep for your career.

Policies

The ultimate authority for course policies is the course syllabus. However, my general academic integrity policy can be found here and my list of policies is here

Topics

The topics to be covered in this course include:

  • The C programming language
  • Compiler and linker invocation and their roles in program development
  • Version control, build, and other systems
  • Representation of in-memory data structures
  • Memory management
  • The kernel/userspace boundary and the system call interface
  • Threads
  • Synchronization primitives and concurrency

Course Structure

The primary deliverables for this course are weekly labs and several larger projects. Labs will consist of short exercises intended to deepen student understanding of course material (and perhaps cover background material for course projects), and will be evaluated in-lab. Course projects will be C language implementations of concepts discussed in class. Projects and labs will make up at least 50% of the final course grade, with the remainder being quizzes and exams.

There are no graded homeworks for this course. Written homework assignments may be given to help students understand the material, and any material covered in homeworks may appear on exams or quizzes, but such assignments will not be directly evaluated.

Programming Assignments

All projects for this course must be implemented in C and compile and run correctly on the course-provided virtual machine image. Students will be expected to use version control and appropriate build tools (such as make) to manage their projects.

Virtual Machine

The virtual machine image can be downloaded here.
