Getting Started

Pre-requisites

You will need to be able to build and run container images using docker or a docker compatible command line interface (e.g. podman). Read the scripts below for further information.

Steps

1. scripts/build_container_image.sh - this will build a container image for you
2. scripts/build_in_container.sh - this will use the container image to do build the project for you
3. scripts/run_benchmark_in_container.sh - this will use the container image to run the benchmark for you
