The teaching is organized as follows:

Learning outcomes

Module: Teoria
-------
The course covers advanced concepts related to operating systems, particularly focusing on distributed and real-time operating systems. Theoretical aspects will be further investigated with practical applications in laboratory.
The course consists of 32 hours of front lectures and 12 hours of practical applications.
Theaching material will be provided by the theacher during the course.


Module: Laboratorio
-------
The course consists of 12 hours of laboratory concerning advanved programming on cluster systems and embedded operating systems.

Examination Methods

Module: Teoria
-------
The final examination consists of a written (oral) test containing theoretical questions and exercises.
The test is passed with a grade of at least 18/30. The maximum grade is 30/30. The oral is optional.

Module: Laboratorio
-------
The final examination consists of a written (oral) test containing theoretical questions and exercises. This test is contextual to the theory examination.

A laboratory project (to be done in a group of 2/3 students) is optional and it may consist of:
- implementing/modifying one or more functionalities of a real-time operating system
- implementing an application for a cluster
- analyzying, evaluating and presenting new trends on distributed or real-time operating systems.
The maximum grande for the project is 4/30 to be added to the grade of the theory's test.
