A benchmark for cache efficient data structures.

Full writeup (explaining the data structures being examined, as well as a discussion of the results) can be found on my blog.

Compiling & running the easy way

scripts contains a Python script that can automate the entire process of building, running, and graphing the output. To use it, you'll need to (once) set up a Python virtual environment like so:

1. $ cd <path to repo>/scripts
2. $ virtualenv env -p python3
3. $ env/bin/pip3 install -r package_requirements.txt

Then, run the script via: $ env/bin/python3 benchmark_and_graph.py

After the program churns for a few minutes, you'll get a new graphs directory full of PNGs.

Compiling & running the hard way

1. $ cmake CMakeLists.txt
2. $ make
3. ./data_structure_benchmarks > my_output_file.txt
4. Set up a Python virtual environment in your scripts directory as above
5. $ cd scripts
6. $ env/bin/python3 graph_results.py --file my_output_file.txt [--min-elements=N] [--max-elements=M]
