Lecture Week 3: The POSIX Interface

Course Meetup: Tuesday, Feb. 9

The next course meetup at on Tuesday, Feb. 9 at 2:00pm on Zoom. We will use the same Zoom link for all course meetups (you can find it in Compass 2g as the announcement for this course).

Special Session - MP1 Introduction on Feb. 11

Instead of our normal office hours on Thursday, the TAs will be holding an MP introduction session at 2:00pm on Thursday, Feb. 11.

Lecture Topics and Videos

This week we will focus on getting started on MP1. In the “regular times” we would have Thursday’s in-person lecture be a TA session to introduce MP1 and I’ve adjusted the lecture videos to reflect that with just three topics this week:

1. Threads in Applications - MediaSpace Video
2. POSIX Interfaces - MediaSpace Video
3. Hourglass Model for Systems Programming Interfaces - MediaSpace Video

Additionally, here’s a PDF of all the lecture slides presented in the videos this week.

Textbook Readings and Course Meetup Recording

You can dive into these topics further in the following textbook chapters:

• Chapter 5: Interlude: Process API
• Chapter 14: Interlude: Memory API
• Course Meetup #3 Zoom Recording
