Exams after the reopening

As a general rule, exams will be conducted without physical attendance in the autumn of 2021, even after the reopening. See the semester page for information about the form of examination in your course. See also more information about examination at the MN Faculty in 2021.

Course content

Presentation of fundamental concepts of distributed objects including local and distributed objects, remote object invocation, communication, parameter passing principles, garbage collection, performance issues and typical applications. We also cover advanced type systems including concepts such as immutability and its application to distributed programming and access control. We also discuss the design of language constructs for parallelism. Throughout we use the programming language Emerald as a base. We dig into the implementation of distributed objects including virtual machines, compilation techniques, run-time typing, dynamic program loading, and how to do distributed garbage collection.

Learning outcome

After completing the course, you will:

  • be able to explain Emerald’s type system and its significance for distribution
  • know the concepts of distribution, immutability, contra-variance, replication, remote procedure calls, mobility, threads, threads synchronization, thread mobility and garbage collection
  • know the main principles of distributed garbage collection, remote calls, threads, object classes, object types, synchronization, reliability and high performance distributed applications
  • be able to program large distributed applications using Emerald with many threads and complex synchronization requirements, and with objects distributed across the entire world
  • know the speed of light and its impact on distributed systems
  • be able to use Planetlab to measure and evaluate the performance of distributed systems and application

Admission to the course

Students admitted at UiO must apply for courses in Studentweb. Students enrolled in other Master's Degree Programmes can, on application, be admitted to the course if this is cleared by their own study programme.

Nordic citizens and applicants residing in the Nordic countries may apply to take this course as a single course student.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures for international applicants

IN1010 – Object-oriented Programming, INF2100 – Programming project (continued), IN2100 – Logic for System Analysis and INF3110 – Programming Languages (continued)

Overlapping courses


2 hours of lectures each week, with 6 hour lectures every 3 weeks. 2 hours of group exercises each week. The course is heavily Learning-by-Doing thru multiple larger programming assignments.

All mandatory assignments must be passed prior to the final exam.

Attending the first lecture is mandatory.


2 home exams account for 25% of the final grade each, while an oral exam (4 hours long written digital if more than 20 candidates) account for 50% of the final grade.

It will also be counted as one of your three attempts to sit the exam for this course, if you sit the exam for one of the following courses: INF5510 - Distributed objects (continued)IN9570 - Distributed Objects

Examination support material

Oral/written exam: All written material allowed

Language of examination

The examination text is given in Norwegian. If the course is taught in English, the examination text will only be given in English. You may answer in Norwegian, Swedish, Danish or English.

Grading scale

Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.

Resit an examination

Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester. Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.
