Learning objectives:
  The goal is to acquaint students with the principles and concepts that are used as a basis of modern operating system kernels.
  Basic concepts, operating system kernel, kernel structure. Parallel programming and synchronization with a view to kernel synchronization. Deadlock, deadlock detection and prevention. Scheduling algorithms for uni-processor systems. Memory management, virtual memory, paging, virtual memory implementation. Input/Output, synchronous and asynchronous I/O, drivers, optimization of disk operations, File systems, disk space allocation, metadata structures, failure recovery, file system examples. Security and protection.
Knowledge and skills required for the course:
  C language programming in Unix environment, computer architecture, Intel x86 assembler, basic principles of operating systems.
Subject specific learning outcomes and competences:
  Students are acquainted with the parallel programming using POSIX threads, usage of synchronization primitives, virtual memory and file system.
Generic learning outcomes and competences:
  A deeper understanding of computer systems and system programming.
Syllabus of lectures:
  1. Kernel structure, interface, system calls, context switch, interrupts, system interface, Unix systems interface, standardization, SVID, XPG.
  2. Processes and POSIX threads, creating processes and threads, threads implementation.
  3. Parallel programming, synchronization, synchronization basics, mutual exclusion using memory read&write.
  4. Synchronization using special instructions on uni-processor and multiprocessor systems with shared memory, priority inversion and solution.
  5. Synchronization tools and programming languages frameworks, classical synchronization tasks and their solutions.
  6. Processor scheduling, strategy, implementation, scheduling algorithms for uni-processor systems.
  7. Resource allocation, deadlock, deadlock avoidance, solutions for CR and SR systems.
  8. Memory architecture, paging, page tables and TLB.
  9. Virtual memory, paging algorithm, page replacement algorithms.
  10. Practical aspects of virtual memory - code sharing, memory sharing, locking, dynamic libraries, file mapping, kernel memory.
  11. Input and output, drivers, synchronous and asynchronous operations, disk I/O optimization.
  12. Files systems, organization, space allocation, free space allocation, failure recovery, Unix file systems, BSD FFS and log based file systems.
  13. Security and protection, system access, data protection, security risks.

Controlled instruction:
  The knowledge of students is examined by the projects and by the final exam.
Progress assessment:
  Written mid-term exam (max. 15 points) and submitted projects in due date. Projects have to be submitted before the deadline, late project submission will be graded 0 points.
