Advanced Operating Systems

• 39 hrs lectures
• 13 hrs projects

• 60 pts final exam (written part)
• 30 pts written tests (test part)
• 10 pts projects

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.

• Hardware/Software Codesign (HSC)
