arithmetic-coding

This repository contains the code for the published work Comprehensive Analysis of Software-Based Fault Tolerance with Arithmetic Coding for Performant Encoding of Integer Calculations at SAFECOMP2022

Requirements

For an accurate performance measurement we use an Linux with PREEMPT_RT. Furthermore, the rtPerfLog library is used for the measurements. This lib is added as submodule and must be updated after cloning.

git submodule init
git submodule update

How to build

CMAKE required. Exeute ./build.sh to build all binaries and dependencies.

Structure of the repository

• codings Contains the encoded operations for each encoding.
• mul_validation Code for the validation with a matrix multiplication.
• plots Some python files to generate the plots in the paper.
• results Output of the metric evalutation and fault simulation.
• rtPerfLog Submodule of rtPerfLog library
• src The source files for the metric evaluation, fault simulation, and performance analysis.
• build.sh Script to build all binaries
• execute-detcap.sh Script to run all metric calculations.
• execute-perf.sh Script to run all perfromance measurements. You may run as root to change the real-time scheduling.
• execute-valid.sh Script to run the perfromance measurements of the matrix multiplication. You may run as root to change the real-time scheduling.
