CS 213: Introduction to Computer Systems, Fall, 2019

Instructor:Peter Dinda (Office Hours: Tuesdays, 3:30-6:30, Mudd 3507 or by appointment)
Teaching Assistant: Brian Suchy (Office Hours: Wednesdays, 12-3, Mudd 3303 (or 3301) or by appointment)
Peer Mentor: Michael Cuevas (Office Hours: Mondays, 4-7, Wilkinson Lab, or by appointment)
Lecture:Tuesdays and Thursdays, 2-3:20pm, Tech L361
Optional Discussion:Wednesdays, 5-, Mudd 3501

CS 213 is a required core course in the Computer Science curriculum in both McCormick and Weinberg. It is also a required course for CS minors in both schools. 213 can also be taken for credit within the Computer Engineering curriculum.

This version of CS 213 has an increased focus on (a) low-level hardware aspects, (b) C programming, (c) the Unix system call interface, and (d) threading/parallelism (including a lab). It will be of particular value in preparing for CS 343 (Operating Systems) and similar courses.

Communication

We will use Canvas to report grades, but for nothing else. For critical announcements, we will send email to the addresses that CAESAR maintains.

For discussion, we will use Piazza: CS 213 Piazza Site. Directing your questions to Piazza will likely produce the fastest response, and everyone else in the class will also benefit. Piazza is configured to allow anonymous posting.

Accounts, Remote Access, Getting Started with Unix

  • You will have a Linux account on the Wilkinson lab, which is very convenient for working together. Mostly, though, you'll be using those machines as terminals. You should also be able to use NUIT labs near Tech (i.e., in Mudd.)
  • You will also have a Linux account on private servers we have set up. These accounts will be discussed in class.
  • We recommend you use ssh (remote login) or FastX (remote graphical desktop) to access the class servers. We will give you more information about FastX in class and/or via Piazza. You can also use X11 tunneled over SSH. You may also find tmux to be useful.
  • If you haven't used Linux or Unix before:
  • Introduction to the Linux environment on our server (Peter Dinda) (YouTube)
    Note that this video spends some time talking about using VNC for graphical remote access to the servers.
    We highly recommend that you instead use FastX. A URL for FastX is available in Piazza.
