In the course of Advanced Operating Systems Concepts (CASE), students will learn to design, implement and analyze operating systems that offer the runtime environment and evaluate its quality. The course content covers issues of architecture that runs an operating system, from servers to mobile environments, hardware support necessary for the OS, types of services offered by operating systems, application requirements and real time control of energy, support for parallelism, application development on OS virtualization techniques and management of the security and safety system and applications. The evaluation of the course will be done by three partial checks throughout the semester, a laboratory examination and a final exam.

Teaching methodology

The teacher presents the topics proposed in the theory sessions, while open discussions among and with students on various topics. Each session includes the theory of motion of various topics related to the class, students work independently on his compte.Les lab follow the issues raised in the theory and serve to entrench the use and evaluation of abstractions and system services operatiu.Per to work in the competition for autonomous learning, the course will be 2 staff work activities related to the services offered by operating systems. The themes of the activities will be defined during the course. Will for example, the introduction of new system calls, the interacio between Android and Linux systems, add the OS services through libraries, performance evaluation system, etc..

Evaluation methodology

The autonomous learning competence is evaluated based on the reports delivered by the student during the course. Its weight is 10% on the final mark.

The technical competences are evaluated based on the theory (40%) and the laboratory exam (50%).

The theory gets evaluated based on the partial and the final exams. The mark of the 3 partial exams is computed as the averaged mean of the 3 tests, with the following weights: 25, 25, and 50%. If this mark is equal or larger than 6.0, attending the final exam is optional.

In case a student attends the final exam, his/her theory mark will be the highest between the mark obtained in the final exam and the averaged mean of the partial exams.
