Coursework and Evaluation
Students are tasked with writing a compiler that compiles programs written in Joos 1W, a fairly large subset of Java, to i386 assembly. The project will be done in groups. The standard size of a group is three. The project will be broken up into several assignments with fixed due dates. The assignments must be submitted to Marmoset. Marks for your code will be reported to you by Marmoset, and your marked written reports will be returned to you by email. After the final assignment deadline, secret tests will be run by Marmoset on your last on-time submission.
The above assignments (including accompanying reports) total 78% of your final mark, if you are in
Students enrolled in CS 644 are required to complete a literature survey on a topic related to compiler construction.
|Assignments 1–5, code submissions||66%|
|Assignments 1–5, report submissions||12%|
(breakdown scaled accordingly)
Marking Policy on Late Submissions
Reports submitted after the assignment deadline will not be marked and will receive a mark of zero. If you cannot finish the assignment by the deadline, submit what you have by the deadline, and explain any unfinished parts in your report.
For code submissions, the following late policy applies:
0.5 × best-on-time + 0.5 × best-overall
where “best-on-time” is the best submission within the assignment deadline, and “best-overall” is the best submission up until the deadline of the last assignment. Examples:
- Group gets 90% marks on a January 20th submission of Assignment 1 and there is no submission after the deadline.
Mark: (0.5 × 90%) + (0.5 × 90%) = 90%
- Group gets 50% marks on a January 20th submission of Assignment 1 and 90% on a February 20th re-submission of Assignment 1.
Mark: (0.5 × 50%) + (0.5 × 90%) = 70%
- Group gets 90% marks on a February 20th submission of Assignment 1.
Mark: (0.5 × 0%) + (0.5 × 90%) = 45%
Submitting an additional solution for an assignment can never reduce your mark.
Marking Policy on Group Work
When working in a group, disagreements sometimes arise. One of the objectives of this course is for you to resolve such disagreements with sufficient, constructive, and frank communication within the group. Therefore, when disagreements arise, discuss them within the group before asking the instructor to intervene. If the group fails to reach a resolution, the group as a whole should arrange a meeting with the instructor. The instructor's role is primarily to mediate the discussion within the group, rather than to intervene in the disagreement. Problems are easier to resolve if handled early. When a problem arises, try to resolve it as soon as possible. Do not leave it until the end of the course.
At the end of the course, the following policies will be used to distribute marks among the group members:
- Normally, each member of the group will be given an equal mark. You should therefore strive to ensure that each group member makes an approximately equal contribution to the project.
- The group may propose a different distribution of the marks, provided all group members consent to the distribution. Such a proposal must be made to the instructor within three days after the due date of the last assignment. The marks will be distributed in such a way that the mean of the marks equals the original group mark and no individual project mark exceeds 100%.
- If agreement cannot be reached, a member of the group must contact the instructor within three days of the due date of the last assignment. The instructor will ask each group member to submit a written statement detailing the contributions of each group member, the nature of the conflict, and the steps that were taken by the group to resolve the conflict. Failure to submit the statement within three days of being asked to do so will result in a mark of zero for that group member. Based on the statements, the instructor will make a final decision about the mark distribution. Note that the instructor will generally not deviate from the equal distribution of marks unless convinced that the group took sufficient and timely steps to resolve the conflict internally.
Should the authorities demand lectures be online, lectures will meet on Zoom. Should the authorities demand lectures be in-person, lectures will meet on campus. Coursework and weighting stay unaffected.
