Course Project Operating Systems Summer 2024

This is the project I have developed for the Saarland University OS course!

Project Parts

You can find more information and implementation details here:

• Project 1: Threads, Synchronization, Scheduling
• Project 2: User Programs
• Project 3: Virtual Memory

Project 1: Threads, Synchronization, Scheduling

1. Implemented an alarm clock without busy-waiting

2. Implemented producer-consumer functions so that users can achieve producer/consumer communication through a bounded buffer.

3. Implemented priority scheduling.

4. Wrote a design document based on my implementation.

Project 2: User Programs

1. Implemented Process Termination Messages: Whenever a user process terminates, because it called exit or for any other reason, prints the process's name and exit code.

2. Implemented argument passing to processes.

3. Implemented these system calls: halt, exit, exec, wait, create, remove, open, filesize, read, write, seek, tell, close.

4. Added denying writes to executables.

5. Wrote a design document based on my implementation.

Project 3: Virtual Memory

1. Implemented frame table

2. Implemented supplemental page table and page fault handler

3. Implemented stack growth

4. Implemented page reclamation

5. Implemented random eviction

6. Implemented an eviction algorithm

7. Wrote a design document based on my implementation.
