Learning objectives

The goal is to acquaint students with the principles and concepts that are used as a basis of modern operating system kernels.

Students are acquainted with the parallel programming using POSIX threads, usage of synchronization primitives, virtual memory and file system.

A deeper understanding of computer systems and system programming.

Recommended prerequisites

Prerequisite knowledge and skills

C language programming in Unix environment, computer architecture, Intel x86 assembler, basic principles of operating systems.
