Dear AoSCS students,

The time window for reviewing the chapters written by the Bochum students is now open and will end next Tuesday, 21.01.2025 at 14:00 (2 PM). Similar to your first phase, you can find the chapters in the dGit and your assigned chapters to review at https://scs24.cs.uni-saarland.de/slides/index.html#review-assignment-bo.

Due to changes in the submission of chapters by Bochum, we had to reassign some of you to review different chapters. Please double-check your review assignments.

The procedure for reviewing a chapter is unchanged from last time. You can find the old instructions and template at https://dcms.cs.uni-saarland.de/ascs_2425/news/view/6. Please upload the reviews to the dCMS.

Tomorrow (03.12.2024) at 14:00 is the deadline for submitting your reviews in the dCMS. Check your personal status to see the open submissions for each topic.
Submit all reviews (note, you only need to submit your two) to the submission for the reviewed topic as a markdown file.

The bidding for your next topic is already open and ends this Thursday (05.12.2024) at 20:00.
You should have received a mail with a link to a survey in the last days. If you didn't receive this mail, let us know.
Please complete this survey as soon as possible, so we can assign the topics and everyone has the chance to start working early.

REVIEW Phase I SB

Written on 26.11.24 by Andreas Schmidt

Dear AoSCS students,

We are entering the REVIEW Phase I for Saarbrücken’s chapters.
Every student has created a branch matching their topic ID and we tagged the review commits with review-id.

Your task during the review phase is the following:

Dear AoSCS students,

We are entering the REVIEW Phase I for Saarbrücken’s chapters.
Every student has created a branch matching their topic ID and we tagged the review commits with review-id.

Your task during the review phase is the following:

  • Check the AoSCS info page under “Topic Assignment”, where your matriculation number appears in the right “Review” column. If you are from SB, your matriculation number has two rows.
  • Go to the repository and search the respective branch(es) or tag(s).
  • If you want to see a live preview, use your local cloned repo to switch to the respective branch and preview, as you would with your own chapter.
  • Write your review into a Markdown file (.md) following our template.

Once you wrote your reviews, and want to submit them (finally) do the following:

  • If you are from SB: check on your dCMS profile page for the paper topic’s submission (you will see all, not only yours, so be careful). Upload the Markdown file there before the deadline (it might be changed until the deadline).
  • If you are from BO: send the file (named like topic-id.md) via email to cs-os-resy-orga@lists.rub.de before the deadline.

Thank you and good luck with the review!

Regards,
The AoSCS Team

Deadlines

Written on 20.11.24 by Andreas Schmidt

Dear AoSCS students,

as we are now entering the stage where you digitally submit "graded" artefacts, we wanted to clarify the deadlines (note these are always on Tuesdays at 14:00 CET):

  • 26.11.: Chapters (Phase I)
  • 03.12.: Reviews (Phase I)
  • 10.12.: Revisions (Phase I)

Dear AoSCS students,

as we are now entering the stage where you digitally submit "graded" artefacts, we wanted to clarify the deadlines (note these are always on Tuesdays at 14:00 CET):

  • 26.11.: Chapters (Phase I)
  • 03.12.: Reviews (Phase I)
  • 10.12.: Revisions (Phase I)

For chapters and revisions, the deadline implies which is the last Git commit we will consider on your branch (the chapter commit is used for review, the revision commit for our evaluation). For the reviews, we will create dCMS submissions that close automatically at that time.

These are the deadlines until the end of the year. We will follow up with another mail for Phase II and the BO Phase.

Dear AoSCS students,
 
Here is a quick outlook for tomorrow.
 
We start with leftovers, i.e. a few more slides on presentation skills will be shown. Afterwards, the remaining sustainability material will be presented, establishing a common foundation for the upcoming presentations.
 
This will not take us the full two hours. Hence, we will also do a technology check for next week's presentation. If you already know how you will present it (technology-wise), we could do a brief check tomorrow. There are basically two options: 1) you provide us with PDFs that we show on the presenter laptop, 2) you enter the BBB room and share your screen from there. Let's make these things clear tomorrow, so that we will have a smooth presentation day.

The AoSCS Team

Dear AoSCS participants,

You should have been added to a dGit repository (or received an invitation to register). Once you write your chapters, this will be needed.

We also assigned you to the topics (the credentials are in the dCMS material). Fortunately, everyone got a cool (1) or an exciting (2) topic according to their judgement.

You can start working your way through the material right away.

Sustainable Computer Systems

 

Registration

If you are interested in taking this seminar, please register after the 11.09.2024 on the faculty's page for seminar assignments: https://seminars.cs.uni-saarland.de/seminars2425.
Registration directly in the dCMS is not possible. You will receive a token from us to register in dCMS once you have been successfully assigned a slot in this seminar by the system.

 

Overview

As the world struggles with climate change, the computing sector's role as a source of greenhouse emissions (and other bad environmental impact) is steadily increasing. This seminar, co-located and co-hosted with the BOSS Team at Ruhr-Universität Bochum (RUB), explores the intersection of computer technology and sustainability—identifying the key challenges of and innovative solutions for a sustainable future with computers. We begin by looking at the origins of carbon emissions and learning to understand where emissions are caused. We then focus on known and new methods for measuring and modeling emissions in computer systems. Finally, we show ways in which systems and software can be adapted to become more sustainable.

Requirements: - Open for advanced Bachelor and any Master students.
- Ideally, you have taken courses from the "systems & software" domain: e.g. Data Networks, Operating Systems, Distributed Systems, Software Engineering.

Student Places: 8

 

Seminar procedure

The final goal of the seminar is to produce a book on sustainable computer systems, with the chapters being written by the students of this seminar. For this purpose, the seminar will be divided into two sprints of about 6 weeks, where in each sprint each student will be assigned a topic. The students task will be to create a presentation and present it to the other students of the seminar and finally write a chapter on this topic. In addition, students are given the task of revieweing other students and revising their own chapters based on the feedback they receive.

Important!

As we must synchronize with the Ruhr-Universität Bochum (RUB), the dates of the in-person meetings are already firm: Tuesdays from 14:00 to 16:00 German time (CEST until Su, 27.10., CET afterwards).
Attendance is compulsory (except in the case of illness or exams etc.); This seminar is not suitable for you if you cannot be present at these times.
No additional exceptions are possible.

 

Registration in LSF/HISPOS

You must register in LSF/HISPOS no later than 3 weeks after the kick-off event.
Otherwise we will not be able to record your grades at the end of the semester.

If your degree program does not use LSF/HISPOS, you will receive an old-fashioned paper certificate to present to your examination office.
Please contact us early regarding this.
