Choose semester

Course content

The course looks at performance issues in distributed systems including server architectures, data placement, scheduling, high performance file systems, resource handling in operating systems, and protocols and mechanisms for distribution and delivery of data. There will be a strong focus on applications that require time dependent delivery at high data rates. The practical work in the course will improve the understanding of system architectures, operating system improvements and hardware support that are meant in particular for dedicated servers and distribution systems.

Learning outcome

The students will understand the technical demands and potential
solutions for distributed system that impose high requirements on
data storage and transport. As a part of this, students will get an
insight into the means of an modifying operating system kernel to
improve performance.

In addition, each PhD student will be given an extended curriculum within the field/research area of the course. The syllabus must be approved by the lecturer so that the student can be admitted to the final exam.


PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.

If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.

PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.
