TDDB68: Concurrent Programming and Operating Systems

Registration, Documentation, Assignments

Lab Registration

The last day to sign up for the labs in Webreg is Thursday 2018-01-18. If you encounter any problems with registration, please contact Felipe Boeira (felipe.boeira@liu.se).

General Information

The assignments are done in pairs, but the examination is individual. This means that it may happen that only one student in a pair recieves the passing grade. You may do the assignments alone if you wish (provided that the lab groups are not full), but a pair always has priority to the computers and assistants.

Beyond the scheduled lab sessions you also have to spend non-scheduled time on these laborations.

For most students Laboration 3 is the most time consuming. You should know that the difficult part of Laborations 1 and 2 lies in understanding the problem, while the difficulty of Laboration 3 lies more in the implementation (especially synchronization issues).


There are three main deadlines related to the lab series:

  • 2018-01-18 Deadline for signing up in webreg
  • 2018-03-14 Deadline to to pass the lab series in order to get the 4 point bonus on the exam, see exam page for details (hard deadline)
  • 2018-03-23 Final deadline to pass the lab series (hard deadline).

Note that the entire lab series (labs 0,1,2,3 and 4) must have been approved by the lab assistant by the time of the deadline. This means that if you demonstrate on the last day and have flaws in the solution, then you will not make the deadline.

If you haven't passed the labs by the time of the final deadline, you will have to wait until the retake period in June or August do demonstrate your solution. After August, the next time to demonstrate will be during the next instance of the course next year.

We recommend you to follow these soft deadlines to be able to finish the labs in time.

  • Lab0: January 19, 2018.
  • Lab1: January 26, 2018.
  • Lab2: February 1, 2018.
  • Lab3: February 24, 2018.
  • Lab4: March 5, 2018.

Lab documentation


You need to demonstrate lab 00, and lab 1, 2, 3 and 4 for your assistant!

Handing in code

In order to ensure that the code being examined by the lab assistant has been submitted by both students in the lab group the following process should be followed.

  1. Always send email from your LiU student account.
  2. Always include the course code in the subject of your email and also information about whether you want to submit code or ask a question. Do not mix the two.
  3. When submitting the code to your lab assistant, include your lab partner in the list of recipients.
  4. Include the following text in your submission:

    We hereby submit this program code as part of the examination for the programming labs in TDDB68 Process programming and operating systems. We guarantee that all submitted code except for parts included from the lab skeleton has been written entirely by us.
    your names

  5. The student not sending the email should reply to all and state: I confirm the contents of the email to which this is a reply.

Rules of the game

The laboration assignments are part of the examination in the TDDB68 course. Therefore you will have to demonstrate your solutions to your laboration assistant. And the assistant will test if you understand the solution. If it is obvious that only one student in a group of two understands the code and the concepts, then only that student will get the passing grade.
Don't cheat!

IDA's general rules and policy for examination of computer labs

Rules for examination of computer lab assignments at IDA

You are expected to do lab assignments in group or individually, as instructed for a course. However, examination is always based on individual performance.

It is not allowed to hand in solutions copied from other students, or from elsewhere, even if you make changes to the solutions. If there is suspicion of such, or any other form of cheating, teachers are obliged to report it to the University Disciplinary Board.

Be prepared to answer questions about details in specific code and its connection to theory. You may also be asked to explain why you have chosen a specific solution. This applies to all group members.

If you foresee problems meeting a deadline, contact your teacher. You can then get some help and maybe the deadline can be set to a later date. It is always better to discuss problems, instead of, e.g., to cheat.

Any kind of academic dishonesty, such as cheating, e.g. plagiarism or use of unauthorized assistance, and failure to comply with university examination rules, may result in the filing of a complaint to the University Disciplinary Board. The potential penalties include suspension, warning.

Policy for handing in computer lab assignments at IDA

For all IDA courses having computer lab assignments there will be one deadline during or at the end of the course. If you fail to make the deadline, you must retake the, possibly new, lab course the next time the course is given.

If a course deviates from this policy, information will be given on the course web pages.
