Objectives of Programme's Learning Outcomes

• Have acquired highly specialised and integrated knowledge and broad skills in the various disciplines of computer science, which come after those within the Bachelor's in computer science.
• Carry out development or innovation projects in IT.
• Apply, mobilise, articulate and promote the knowledge and skills acquired in order to contribute to the achievement of a development or innovation project.
• Master the complexity of such work and take into account the objectives and constraints which characterise it.
• Master communication techniques.
• Communicate, both orally and in writing, their findings, original proposals, knowledge and underlying principles, in a clear, structured and justified manner.
• Develop and integrate a high degree of autonomy.
• Develop and integrate a high degree of autonomy to evolve in new contexts.
• Apply scientific methodology.
• Demonstrate thoroughness, independence, creativity, intellectual honesty, and ethical values.

Learning Outcomes of UE

By the end of this course, students will have mastered the fundamental principles governing the development of modern operating systems. They will be able to explain the interactions between different components of operating systems and solve complex problems related to resource management and synchronization.

Students will have applied their knowledge by developing scripts and system programs in C to automate process and file management in a UNIX environment.

UE Content: description and pedagogical relevance

Introduction: Functions and characteristics of an operating system, resource allocation and management, brief historical overview.

CPU Virtualization: Process abstraction, interface, process states, data structures, limited direct execution, system calls, context switches, preemption, scheduling algorithms.

Memory Virtualization: Address space abstraction, static and dynamic relocation, segmentation, paging, translation lookaside buffer (TLB), page table storage, swap management.

Concurrency: Thread abstraction, synchronization primitives (locks, condition variables, semaphores), OS and hardware support for their implementation, classic concurrency problems (Producer/Consumer, Thread Throttling, Dining Philosophers), common concurrency bugs, detailed discussion of deadlocks.

Persistence: Input/output devices, disks (operation, scheduling, RAID), file systems (POSIX interface, implementation, journaling).

All concepts are illustrated in the xv6 operating system.

UNIX: Manipulation of processes, file systems, and the kernel through C programs (POSIX interface) and shell scripts.

Prior Experience

Mastery of a programming language, computer architecture, working of a processor, interrupt mechanism, memory addressing, caching.
