Reproducing Experiments

This repository contains the source code and our reproducibility artifacts for our paper. Due to the plethora of dependencies required by our competitors, we provide an easy to use Docker image to quickly reproduce our results. Alternatively, you can look at the Dockerfile to see all libraries, tools, and commands necessary to compile the different competitors.

Building the Docker Image

Run the following command to build the Docker image. Building the image takes about 10 minutes, as some packages (including LaTeX for the plots) have to be installed. Note that your machine needs to support the AVX2 instruction set extension to successfully run the experiments.

docker build -t mmphf_experiments --no-cache .

Some compiler warnings (red) are expected when building competitors and will not prevent building the image or running the experiments. Please ignore them!

Running the Experiments

Due to the long total running time of all experiments in our paper, we provide run scripts for a slightly simplified version of the experiments. They run fewer iterations and output fewer data points.

You can modify the benchmarks scripts in scripts/dockerVolume if you want to change the number of runs or data points. This does not require the Docker image to recompile. Different experiments can be started by using the following command:

docker run --interactive --tty -v "$(pwd)/scripts/dockerVolume:/opt/dockerVolume" mmphf_experiments /opt/dockerVolume/<script>.sh

<script> depends on the experiment you want to run.

The resulting plots can be found in scripts/dockerVolume and have the file extension .pdf.
