Syscall Simulator

Description

A simple syscall simulator.

Usage

To run the simulator, use the following command:

./sim <trace_file> <vector_table_file> <output_file>

Makefile Instructions

Default Rule

To build the program use:

make

Running Specific Tests

To run specific tests, use the following commands:

make test1
make test2
make test3
make test4
make test5
# ... up to test20

Running All Tests

To run all tests, use:

make test

Cleaning Up

To remove the executable, object file, and ALL test execution files in, use:

make clean

Notes

• Ensure you have make installed and properly configured.
• Running tests together may appear to repeat randomness due to fast execution; run tests individually to see true randomness.

Analyzing Results

The analyze.py script can be used to generate pie charts and bar graphs from the execution results.

Usage

To analyze a single execution file and generate pie charts:

python3 analyze.py <execution_file>
# ... execution file is the output of the simulator

Example

python3 analyze.py ./path/to/execution1.txt
python3 analyze.py ./path/to/execution2.txt

The script will generate the following images:

• execution_pie_charts.png: Pie charts showing the distribution of IO Time, CPU Time, and Overhead for each execution.
• average_metrics_bar_graph.png: Bar graph showing the average metrics across the executions.

Optionally, you can display the charts while saving by uncommenting plt.show() in the script.
