Cache Simulator - CO262 Course Project

This project is a Cache Simulator designed specifically to analyze the performance of Advanced Cache Replacement Algorithms. The simulator is a cpp program which can simulate cache replacement algorithms like :

1. SRRIP : Static Re-Reference Interval Prediction
2. LRU : Least recently used
3. NRU : Not recently used
4. LFU : Least frequently used
5. FIFO : First in first out
6. PLRU : Pseudo Least recently used
7. ARC : Adaptive replacement cache

Getting Started

Make sure you have the latest g++ compiler installed on your system.

Clone this github repository

git clone https://github.com/vybhavpai/Cache-Replacement-Algorithm-Simulator

Download the traces from here (Click on Link to download):

Trace - Row Major Matrix Multiplication

Trace - Tile

Trace - Regular Matrix Multiplication

After downloading the traces move them into the repository.

Simulate Cache Replacement Algorithm

To compile and run the simulator on traces:

Step 1 :

$ g++ simulator.cpp

Step 2:

$ gzip -dc (trace_name.gz) | ./a.out (replacement_algorithm in small) (no_of_ways) (block_size)

Step 3:

Wait for 15 - 20 minutes for each simulation. 

Example

$ g++ simulator.cpp
$ gzip -dc trace_tile.gz | ./a.out srrip 2 32

Now wait for some time.....

The result will appear something like this:

103284902 is number of hits 103745282 is total input
0.995562 is hit ratio
73678224 is number of reads 
30067058 number of writes 
456979487 is total number of clock cycles

That's all folks!!!
