Your final grade for the course will be based on the following weights:
The project in 18-742 is an open-ended research project, done in groups of three (or two, with permission of the instructor). The project requires a proposal, a project status report, and a final report (both written and presented).
There are no official texts for the course. If you're not familiar
with the background material,
you may wish to look at:
You might take a peek at the following CMU undergrad systems courses for
background
information on computer systems (15-213/18-213),
computer architecture (18-447),
and parallel computer architecture (15-418).
There are also other PhD-level computer architecture courses, such as 18-740 and 15-740.
Also available as an ical file that you can subscribe to.
Note: Class will meet on average two times per week, but we will frontload the lectures at the begining of the semester. This schedule is subject to change, so please hold all three days (Mon, Wed, Fri) open each week.
