Solo Project Deadline Approaching - Grading Information

Written on 05.11.25 by Joachim Meyer

Hi all,

here's a reminder that the solo project has a hard deadline for submission, this Sunday, Nov 9th, 23:59 CET.
Please ensure that the state of the project you want to hand in is available on the main branch of your regexfe repository in our GitLab.

Hi all,

here's a reminder that the solo project has a hard deadline for submission, this Sunday, Nov 9th, 23:59 CET.
Please ensure that the state of the project you want to hand in is available on the main branch of your regexfe repository in our GitLab.
If you do not see your project on the progress page yet, there is something wrong, and we will not grade your project. So do get in contact with us if that is the case.

The group project phase starts next week.
The registration for this ends on Tuesday, Nov 11th, 23:59 CET.
Please find yourselves a group of 2-3 and follow the respective paragraph for registration from: https://cms.sic.saarland/cc2526/4/How_to_Attend

We also want to make sure you understand what the impact of the solo project is with regard to your final grade.
Our already communicated grading statement is: "To get a course certificate, students must pass the final exam and the projects. If you pass both, the exam and the projects, the final grades for the course will be computed as the (equally weighted) arithmetic mean between your exam grade and your project grade, rounded towards your exam grade."
The solo project accounts for 20% of the project grade.
As the project grade accounts for ~50% (only approximately due to the rounding towards the exam grade) of the final course grade, the final impact of the solo project is ~10%.
You do not have to pass the solo project to be able to continue the course.
However, you have to pass the project part of the course, so if you don't do the solo project, you have to get at least 62.5% on the group project to pass the course.
For the grade, we do consider the number of tests that your implementation passes.
We have no hidden tests, so the tests that count are exclusively the tests that you already get feedback on at: https://cc.cdl.uni-saarland.de/results/progress.php
To determine the final project grade, we will have a project discussion with each group after the semester.
There, we will discuss both the solo and the group projects to verify your level of contribution to the projects.

Good luck!

Solo Project Office Hour Nov 4. 10-11:30

We will offer an Office Hour for the project, next Tuesday, Nov 4, 10-11:30, Room E1.3 4.01.

This office hour is the place to get support with the RegEx project and receive hints on what might be missing to pass more tests.

We refined the project description in a few places, so it might be a good time to have a look at the updates.
The new version can be found in the Materials list, and an overview of the errata can be found in the forum: https://cc-discourse.cdl.uni-saarland.de/t/regex-project-errata-common-issues/

Please remember, the project is due 2025-Nov-9, 23:59, CET.
This is a hard deadline!

Hello everyone,

please note that the first exercise sheet is now available in the Materials section.

Secondly, a quick reminder that the project registration will close tonight, 23:59.
If you haven't followed the solo project registration steps from the How To Attend page, this is your last reminder to do so.

We will make the assignment for the solo project available in the Materials section tomorrow by noon.

If you have any questions, please post them in the Forum - this is the primary contact point for the course!

Welcome everybody!

We're glad you chose to hear Compiler Construction (CC) this year.

Tomorrow, Oct 14, we're kicking the lecture off at 08:30 in lecture hall 003 (E 1.3).
We will review the course's organization, including the two points below, and then dive into the topic.

If you registered early, you might not have been able to select a tutorial preference yet. Please select your tutorial preference until Sunday, 19 Oct.
If you are not yet registered for the course, but want to attend, please register until Sunday as well.

Finally, to register for the project: please follow the steps at How to Attend.

See you in class!

Compiler Construction

The course treats compiler construction for imperative programming languages. This includes lexical, syntactical, and semantic analysis as well as static program analysis, optimization, and code generation. This course provides all necessary theoretical knowledge required to implement a compiler from scratch, which forms the practical part of the lecture.

 

Syllabus

  • Lexing and Parsing (LL, LR)
  • Semantic Analysis, Type Checking
  • Foundations of Program Analysis by Abstract Interpretation
  • Program Optimizations and their Analyses
  • SSA
  • LLVM
  • Instruction Selection
  • Scheduling
  • Register Allocation
  • Polyhedral Compilation
  • DSLs

 

Lecture Dates

  • The lectures will be recorded and made available online.
  • Time and Place: Tuesdays: 8:30, Thursdays: 12:15, E1.3 HS003
  • First Lecture: Tuesday, 14.10., 8:30, E1.3 HS003

 

Modus Operandi

There will be voluntary exercise sheets that are discussed in tutorials.

To get a course certificate, students must pass the final exam and the projects. If you pass both, the exam and the projects, the final grades for the course will be computed as the (equally weighted) arithmetic mean between your exam grade and your project grade, rounded towards your exam grade.

The practical projects are to be implemented in C++. The first individually, the second in groups of 2-3 students. The grade will depend on how many tests your projects pass, how much the individual students contributed to the project, and the demonstrated understanding of the project in the oral presentation. In the end of the lecture period, we will host a competition for the student compiler implementations. The top performing groups of the competition will earn a 0.3 (or 0.4) bonus to their total course grades.
