Submission artifact

This directory contains the artifact submission for the CHES 2024 paper Fast and Clean: Auditable high-performance assembly via constraint solving.

The artifact enables interested readers to:

  1. Optimize: Reproduce the SLOTHY optimizations described in the paper.
  2. Test: Validate the functional correctness of the optimized code through tests.
  3. Benchmark: If suitable development boards are available, evaluate the performance of the optimized code.

Setup

Optimization requires the SLOTHY repository. For testing and benchmarking, we recommend and describe the use of the pqmx and pqax test repositories for Cortex-M and Cortex-A. Benchmarking further requires the availability of suitable devices or development boards.

Docker

SLOTHY, pqmx and pqax have a number of dependencies that can be cumbersome to setup manually, including Google OR-Tools and cross-compilers for AArch64 and Armv8.1-M.

For convenience, this directory contains a Dockerfile slothy.Dockerfile establishing an Ubuntu-22.04-based Docker image with SLOTHY, pqax and pqmx setup and ready for use.

Build image

  • Build the image:
docker build -f slothy.Dockerfile -t slothy_image .
  • Check success:
docker image ls

should show a line like this:

% docker image ls
REPOSITORY      TAG       IMAGE ID       CREATED         SIZE
slothy_image    latest    b009755ab33e   2 hours ago     3.5GB

Create and run container

  • Create docker container from image
% docker run --name slothy_container -d -it slothy_image /bin/bash
e06f3c0155e552ce41a7fecdccf27f18e04e888ee30b5a43b48b98326df360bd
  • Check that the container is running
% docker container ls
CONTAINER ID   IMAGE        COMMAND       CREATED          STATUS          PORTS     NAMES
e06f3c0155e5   slothy_image "/bin/bash"   20 seconds ago   Up 19 seconds             slothy_container
  • Start shell in docker container
% docker exec -it slothy_container /bin/bash
root@e06f3c0155e5:/slothy#

Here are all steps together:

docker build -f slothy.Dockerfile -t slothy_image .
docker image ls
docker run --name slothy_container -d -it slothy_image /bin/bash
docker container ls
docker exec -it slothy_container /bin/bash

Manual build

For a manual local build, you largely follow the steps in slothy.Dockerfile. At the top-level, you should have a directory structured as follows:

* artifact
* |-- pqmx
*     |-- submodules
*         |-- slothy # symlink to slothy repository
* |-- pqax
*     |-- submodules
*         |-- slothy # symlink to slothy repository
* |-- slothy

Note that to avoid having three copies of SLOTHY, you should not use git submodule in the pqmx and pqax repositories, but symlink the SLOTHY repository into the submodule location.

For the SLOTHY repository, the main dependency is Google OR-Tools; see the README in the SLOTHY repository for setup instructions (those are also followed in the Dockerfile).

Using the artifact

Within either the docker container or your local copy of SLOTHY, please see slothy/paper/README.md for a detailed description of how to reproduce, test and benchmark the results of the paper. This file is also available online here.
