os2's Introduction

Memory Management Simulation

C project

Details:
Produce statistics based on the behavior of page replacement algorithms LRU and Second Chance
Two Threads read 2 different trace files alternately and load them into main memory.
Main memory is implemented by a queue-array.
The virtual memory is implemented by a hash table for each thread.

Statistics include:
Queue size (memory frames number),
Total iterations, Total P1 (gcc) iterations, Total P2 (bzip) iterations,
Total pagefaults, Total hits, Total updates,
Total reads from disk, Total writes on disk

What you need:

- A Linux Distribution OS

- In terminal:

sudo apt install gcc -y

sudo apt install make -y

In the project folder, open a terminal

Compile with: `make all`

Execution: `./main.ex [algorithm (0/1)] [frames number] [q] (max entries)`

~ Page replacement algorithm options are 0 for LRU and 1 for Second Chance

~ frames number stands for memory capacity

~ q stands for continuous trace entries a thread will refer before switching to the other thread

~ max entries is the total entries (from both threads) that the simulation will stop at

Example executions:

`./main.ex 0 96 10 400`

`./main.ex 0 2048 11 100000`

`./main.ex 1 2 1 500000`

`./main.ex 1 5120 17 2000000`
