Operating System Concepts implemented in Rust

This is for demonstration purposes only.

Implementations

1. Non-uniform memory (NUMA) is implemented simply using a random delay whenever we dereference into memory.
2. There is a full scheduler implementation.
3. There is a full multi-level feedback queue implementation.
4. Disks including magnetic disks with FCFS, SSTF, SCAN, CSCAN, CLOOK.
5. Raid configurations including RAID0, RAID1, RAID3, RAID4
6. File allocation methods, specificially linked and indexed.
7. Added memory paging, with a pager, logical addresses and translation.

Examples

1. asyn_dynamic.rs Asymmetric multiprogramming with dynamic dispatching along with processor affinities and non-uniform memory access (NUMA)
2. assymmp.rs Asymmetric multiprogramming.
3. numa.rs Non-uniform memory access (NUMA).
4. uma.rs Uniform memory access (UMA)
5. symmp.rs Symmetric multiprogramming.
